一步一步学role角色5-使用ansible配置supervisor进程管理角色

1. 概述

这是一个序列总结文档。

第1节 ansible role角色(1) 中，我们阅读了官方文档，并且知道了角色相关的概念。
第2节 ansible role角色(2)--创建第一个role角色创建一个简单的测试role角色。
第3节 ansible role角色(3)--一步一步学role角色，base基础角色配置。
第4节 ansible role角色(4)--include的使用，base基础角色配置优化，拆分任务功能，引入include关键字。

本节是在前几节的基础上，使用miniconda配置Python环境，对应Python版本为 3.10.13，并设置supervisor进程管理工具环境。引入vars/main.yml配置文件，设置变量配置信息。

1.1 VirtualBox虚拟机信息记录

序号	虚拟机	主机名	IP	CPU	内存	说明
1	ansible-master	ansible	192.168.56.120	2核	4G	Ansible控制节点
2	ansible-node1	node1	192.168.56.121	2核	2G	Ansible工作节点1
3	ansible-node2	node2	192.168.56.122	2核	2G	Ansible工作节点2
4	ansible-node3	node3	192.168.56.123	2核	2G	Ansible工作节点3

1.2. 回顾与展望

上节我编写了一个可以实际使用的base角色，但使用yum安装Python的版本（Python 3.6.8）较低，Python官方已经不再支持。因此本节就使用miniconda来配置高版本的Python。

本篇文章不介绍miniconda如何使用，miniconda的使用，可参考 miniconda的使用。着重介绍如何创建supervisor进程管理角色。

该角色包含以下功能：

1. 将miniconda安装程序上传到远程节点。
1. 校验miniconda安装程序SHA256散列值。
1. 指定miniconda安装目录，在非交互模式下安装miniconda。
1. 在conda环境下，创建supervisor虚拟环境。
1. 在supervisor虚拟环境下安装Python第三方包supervisor。
1. 复制supervisor进程管理工具配置文件/etc/supervisord.conf。
1. 创建目录/etc/supervisord.d，用于存放supervisor进程管理工具管理的应用配置文件。
1. 复制测试应用配置文件app.ini到目录/etc/supervisord.d中。
1. 复制启动文件supervisord.service到路径 /usr/lib/systemd/system/supervisord.service。
1. 启动supervisord服务。
1. 设置supervisor相关快捷命令。

1.3 规划

现在对以上11个任务进行分类，分成几个小的任务组。

可以将任务1-3分成一个任务组，用来安装miniconda，当独创建一个任务文件miniconda.yaml。
将任务4，创建supervisor虚拟环境，当作一个独立任务，创建任务文件virtual_env.yaml。
将任务5-10分成一个任务组，用来配置supervisor进程管理环境，创建任务文件supervisor.yaml。
最后，将任务11单独作为一个任务组，用来创建快捷命令，创建任务文件alias.yaml。

然后，再创建一个主任务配置文件main.yml，将以上四个子任务包括进来。

以下是最终完成后的文件结构：

[root@ansible ansible_playbooks]# tree roles/supervisor
roles/supervisor
├── defaults
│   └── main.yml
├── files
│   ├── app.ini
│   ├── Miniconda3-py310_24.1.2-0-Linux-x86_64.sh
│   └── sha256info.txt
├── tasks
│   ├── alias.yaml
│   ├── main.yml
│   ├── miniconda.yaml
│   ├── supervisor.yaml
│   └── virtual_env.yaml
├── templates
│   ├── alias_supervisor.sh.j2
│   ├── condarc.j2
│   ├── supervisord.conf.j2
│   └── supervisord.service.j2
└── vars
    └── main.yml

5 directories, 14 files
[root@ansible ansible_playbooks]#

2. 任务编写

2.1 创建主机清单配置文件

我们测试时，使用的是三个虚拟机作为工作节点。因此我们可以编写主机清单配置文件hosts.ini，其内容如下：

ini

[supervisorhosts]
192.168.56.121 hostname=ansible-node1
192.168.56.122 hostname=ansible-node2
192.168.56.123 hostname=ansible-node3

在我们编写测试角色相关配置文件时，可以仅使用某一个工作节点，待在这个工作节点上面将整个角色任务都能够正常跑通后，再将所有节点放开。

因此测试时，可以这样配置：

ini

[supervisorhosts]
192.168.56.121 hostname=ansible-node1
# 192.168.56.122 hostname=ansible-node2
# 192.168.56.123 hostname=ansible-node3

即，仅在第一个工作节点上面进行角色任务的编写。

2.2 创建剧本文件

创建一个剧本文件supervisor.yml，由该文件来调用角色任务，其内容如下：

yaml

---
- hosts: supervisorhosts
  roles:
    - supervisor

2.3 角色任务main.yml

该配置文件用来定义角色中包含哪些子任务，roles/supervisor/tasks/main.yml配置内容如下：

yaml

---
# supervisor角色任务
# 安装minicoda
- include: miniconda.yaml
# 创建虚拟环境
- include: virtual_env.yaml
# 配置supervisor进程管理工具
- include: supervisor.yaml
# 创建快捷命令
- include: alias.yaml

为了分步测试，比如，最开始只想测试【安装minicoda】这个任务，就可以将下面这个子任务注释掉，像下面这样：

yaml

---
# supervisor角色任务
# 安装mincoda
- include: miniconda.yaml
# 创建虚拟环境
#- include: virtual_env.yaml
# 配置supervisor进程管理工具
#- include: supervisor.yaml
# 创建快捷命令
#- include: alias.yaml

这样的话，就可以将精力集中在自己关心的任务上，等前面的任务配置验证无误后，再将后面的任务的注释去掉，测试下一个任务。

2.4 任务一-安装mincoda

这个任务，由roles/supervisor/tasks/miniconda.yaml定义，查看该文件内容：

yaml

---
- name: Copy install shell file
  ansible.builtin.copy:
    src: "{{ MINICONDA_SHELL_FILENAME }}"
    dest: "/tmp/{{ MINICONDA_SHELL_FILENAME }}"
    force: yes
    backup: yes
    remote_src: no
    mode: u=rwx,g=r,o=r

- name: Copy the sha256 info file
  ansible.builtin.copy:
    src: sha256info.txt
    dest: /tmp/sha256info.txt
    force: yes
    backup: yes
    remote_src: no

- name: Check the sha256 value of the shell file
  ansible.builtin.command:
    cmd: sha256sum -c sha256info.txt
    chdir: /tmp
  register: result
  failed_when:
    - result.rc != 0

- name: Copy condarc config file
  ansible.builtin.template:
    src: condarc.j2
    dest: "/root/.condarc"
    force: yes
    backup: yes
    remote_src: no

- name: Install miniconda
  ansible.builtin.command:
    # cmd: "/tmp/Miniconda3-py310_24.1.2-0-Linux-x86_64.sh -b -p /srv/miniconda3"
    cmd: "/tmp/{{ MINICONDA_SHELL_FILENAME }} -b -p {{ MINICONDA_BASE_DIR }}"

- name: Remove install shell file
  ansible.builtin.file:
    path: "/tmp/{{ MINICONDA_SHELL_FILENAME }}"
    state: absent

可以看到，这个任务中，又分了6个子任务：

任务1-Copy install shell file，复制从 https://docs.anaconda.com/free/miniconda/miniconda-other-installer-links/ 下载的miniconda shell安装文件到远程主机上。手动下载的安装文件保存到 roles/supervisor/files/目录下。

[root@ansible ansible_playbooks]# ll roles/supervisor/files/
total 131796
-rw-r--r--. 1 root root        36 Apr 24 22:36 app.ini
-rw-r--r--. 1 root root 134948792 Apr 18 23:00 Miniconda3-py310_24.1.2-0-Linux-x86_64.sh
-rw-r--r--. 1 root root       108 May 22 22:17 sha256info.txt
[root@ansible ansible_playbooks]# cd roles/supervisor/files/
[root@ansible files]# cat sha256info.txt
8eb5999c2f7ac6189690d95ae5ec911032fa6697ae4b34eb3235802086566d78  Miniconda3-py310_24.1.2-0-Linux-x86_64.sh
[root@ansible files]# sha256sum -c sha256info.txt
Miniconda3-py310_24.1.2-0-Linux-x86_64.sh: OK
[root@ansible files]#

任务2-Copy the sha256 info file，复制散列校验文件roles/supervisor/files/sha256info.txt到远程主机上。

这个文件可以通过下面的命令生成：

[root@ansible files]# sha256sum Miniconda3-py310_24.1.2-0-Linux-x86_64.sh
8eb5999c2f7ac6189690d95ae5ec911032fa6697ae4b34eb3235802086566d78  Miniconda3-py310_24.1.2-0-Linux-x86_64.sh
[root@ansible files]#

通过该命令查出的sha256散列值，刚好可以与miniconda官网上给出的散列值进行对比，散列值相同则说明文件是正常的。

任务3-Check the sha256 value of the shell file，则会校验复制到远程主机上面的miniconda shell安装文件散列值对不对，不对的话，则会异常，不继续执行后续步骤。
任务4-Copy condarc config file，复制condarc的配置文件到远程主机，加速miniconda的安装。
任务5-Install miniconda，执行miniconda安装脚本来安装miniconda，并指定安装目录。
任务6-Remove install shell file，安装完成后，删除掉复制到远程主机上面miniconda安装脚本，释放磁盘空间。

在roles/supervisor/tasks/miniconda.yaml文件中，可以看到使用了一些双大括号包裹的配置，如"{{ MINICONDA_SHELL_FILENAME }}"，这个是变量的引用。下面就来说明一下变量。

2.5 默认变量

在roles/supervisor/defaults/main.yml中定义了一些角色中使用的默认变量：

变量名使用大写形式，如MINICONDA_SHELL_FILENAME。
一行定义一个变量名。

yaml

---
# 从 https://docs.anaconda.com/free/miniconda/miniconda-other-installer-links/ 下载的miniconda shell安装文件的名称
MINICONDA_SHELL_FILENAME: Miniconda3-py310_24.1.2-0-Linux-x86_64.sh
# miniconda虚拟环境目录，Ansible会将miniconda环境安装到该目录下
MINICONDA_BASE_DIR: /srv/miniconda3
# 虚拟环境名称
VIRTUAL_ENV_NAME: supervisorPython3.10.13
# 虚拟环境Python版本
VIRTUAL_PYTHON_VERSION: 3.10.13
# supervisor服务的基础目录，在该目录下创建 logs, socket, pid等目录，变量路径最后不需要带斜杠
SUPERVISOR_BASE_DIR: /srv/supervisor
# supervisor服务的配置文件
SUPERVISORD_CONFIG_FILE: /etc/supervisord.conf
# 虚拟环境supervisor可执行文件路径,如 /srv/miniconda3/envs/supervisorPython3.10.13/bin
SUPERVISORD_DIR_PATH: "{{ MINICONDA_BASE_DIR }}/envs/{{ VIRTUAL_ENV_NAME }}/bin"
# 登陆supervisor web控制台的用户名
SUPERVISOR_USERNAME: admin
# 登陆supervisor web控制台的密码
SUPERVISOR_PASSWORD: admin@123

这些变量可以直接在角色中的任务中使用，也可以在roles/supervisor/templates/模板文件夹下的模板中使用。

2.6 与远程主机相关的变量

可以将远程主机相关的变量，如IP信息等，定义在roles/supervisor/vars/main.yml变量配置文件中。如我定义了一个HOST_IP，来获取远程主机的IP值：

yaml

---
HOST_IP: "{{ hostvars[inventory_hostname]['inventory_hostname'] }}"

2.7 内容不动态渲染的文件

在roles/supervisor/files/文件夹保存的文件，会原样从Ansible控制主机复制到远程主机上，其中没有使用定义的变量。在任务配置文件中应使用ansible.builtin.copy模块，而不是ansible.builtin.template模块。

示例：

# 查看roles/supervisor/files 文件夹有哪些文件
[root@ansible ansible_playbooks]# ll roles/supervisor/files/
total 131796
-rw-r--r--. 1 root root        36 Apr 24 22:36 app.ini
-rw-r--r--. 1 root root 134948792 Apr 18 23:00 Miniconda3-py310_24.1.2-0-Linux-x86_64.sh
-rw-r--r--. 1 root root       108 May 22 22:17 sha256info.txt


# 查看散列校验文件的内容
[root@ansible ansible_playbooks]# cat roles/supervisor/files/sha256info.txt
8eb5999c2f7ac6189690d95ae5ec911032fa6697ae4b34eb3235802086566d78  Miniconda3-py310_24.1.2-0-Linux-x86_64.sh
[root@ansible ansible_playbooks]#

# 查看用于配置supervisor测试应用的配置文件
[root@ansible ansible_playbooks]# cat roles/supervisor/files/app.ini
[program:testapp]
command=/bin/cat

[root@ansible ansible_playbooks]#

2.8 内容动态渲染的文件

在roles/supervisor/templates/文件夹保存的文件，会将引用变量的位置，用变量的值来进行代替，并渲染成最终的值。在任务配置文件中应使用ansible.builtin.template模块，而不是ansible.builtin.copy模块，刚好与上一节的内容不动态渲染的文件使用的模块相反。

当然，如果你在roles/supervisor/templates/文件夹保存的文件，没使用变量，此时也应使用ansible.builtin.template模块来复制文件，不能用ansible.builtin.copy模块来复制文件。

示例：

# condarc.j2中没有使用变量，但在`Copy condarc config file`任务中还是使用的ansible.builtin.template模块
[root@ansible ansible_playbooks]# cat roles/supervisor/templates/condarc.j2

[root@ansible ansible_playbooks]#

# supervisord.service.j2中使用了默认变量SUPERVISORD_DIR_PATH和SUPERVISORD_CONFIG_FILE
[root@ansible ansible_playbooks]# cat roles/supervisor/templates/supervisord.service.j2

[Install]
WantedBy=multi-user.target
[root@ansible ansible_playbooks]#

2.9 尝试运行第一个任务-安装mincoda

在运行任务前，再次确认一下剧本文件和主机清单配置：

[root@ansible ansible_playbooks]# cat supervisor.yml
---
- hosts: supervisorhosts
  roles:
    - supervisor

[root@ansible ansible_playbooks]# cat hosts.ini
[supervisorhosts]
192.168.56.121 hostname=ansible-node1
# 192.168.56.122 hostname=ansible-node2
# 192.168.56.123 hostname=ansible-node3

[root@ansible ansible_playbooks]#

由于我当前正在测试自己写的角色任务文件，只选择一个工作节点来测试，另外两个工作节点先注释掉，这样可以提升测试效率。

执行命令ansible-playbook -i hosts.ini supervisor.yml -v来调用剧本：

[root@ansible ansible_playbooks]# ansible-playbook -i hosts.ini supervisor.yml -v
Using /etc/ansible/ansible.cfg as config file

可以看到，预期的文件已经有了，miniconda也安装到MINICONDA_BASE_DIR变量指定的目录/srv/miniconda3里面了，并且能够执行conda相关的命令。

此时，只有一个base环境。

可以看到，miniconda成功安装，并正常可用了，说明第一个任务配置是对的。

2.10 任务二-创建虚拟环境

任务二创建虚拟环境，使用的是virtual_env.yaml子任务，由roles/supervisor/tasks/virtual_env.yaml定义，查看该文件内容：

yaml

---
- name: Create supervisor virtual environment
  ansible.builtin.command:
    # cmd: "/srv/miniconda3/bin/conda create --yes --name supervisorPython3.10.13 python=3.10.13"
    cmd: "{{ MINICONDA_BASE_DIR }}/bin/conda create --yes --name {{ VIRTUAL_ENV_NAME }} python={{ VIRTUAL_PYTHON_VERSION }}"

- name: Show virtual environments
  ansible.builtin.command:
    # cmd: "/srv/miniconda3/bin/conda env list"
    cmd: "{{ MINICONDA_BASE_DIR }}/bin/conda env list"
  changed_when: False

- name: Show virtual Python version
  ansible.builtin.command:
    # cmd: "/srv/miniconda/envs/supervisorPython3.10.13/bin/python -V"
    cmd: "{{ MINICONDA_BASE_DIR }}/envs/{{ VIRTUAL_ENV_NAME }}/bin/python -V"
  changed_when: False

实际上，就只用执行类似/srv/miniconda3/bin/conda create --yes --name supervisorPython3.10.13 python=3.10.13这样的命令，来创建一个名为supervisorPython3.10.13的虚拟环境，而虚拟环境的名称和Python的版本，则是由默认变量VIRTUAL_ENV_NAME和VIRTUAL_PYTHON_VERSION来定义的，2.5节中已经说明。

由于任务一已经测试完成，我们此时只想测试第二个任务，因此可以调整roles/supervisor/tasks/main.yml配置内容中的include情况，修改成这样的：

yaml

---
# supervisor角色任务
# 安装mincoda
# - include: miniconda.yaml
# 创建虚拟环境
- include: virtual_env.yaml
# 配置supervisor进程管理工具
#- include: supervisor.yaml
# 创建快捷命令
#- include: alias.yaml

此时，执行剧本：

[root@ansible ansible_playbooks]# ansible-playbook -i hosts.ini supervisor.yml -v
Using /etc/ansible/ansible.cfg as config file

[root@ansible-node1 bin]# /srv/miniconda3/envs/supervisorPython3.10.13/bin/python -V
Python 3.10.13

可以看到，虚拟环境supervisorPython3.10.13创建成功，对应虚拟环境的Python版本是Python 3.10.13。

2.11 任务三-配置supervisor进程管理工具

上一节我们已经创建了一个虚拟环境supervisorPython3.10.13，

下面在该虚拟环境下安装supervisor包及其依赖。然后将supervisord.conf和supervisord.service等配置文件复制到远程主机，最后启动supervisord服务。

由roles/supervisor/tasks/supervisor.yaml定义，查看该文件内容：

yaml

---
- name: Install python package supervisor
  ansible.builtin.pip:
    name: supervisor
    # /srv/miniconda3/envs/supervisorPython3.10.13/bin/pip
    executable: "{{ MINICONDA_BASE_DIR }}/envs/{{ VIRTUAL_ENV_NAME }}/bin/pip"
  vars:
    ansible_python_interpreter: "{{ MINICONDA_BASE_DIR }}/envs/{{ VIRTUAL_ENV_NAME }}/bin/python"

- name: Show supervisor executable files
  ansible.builtin.find:
    paths: "{{ MINICONDA_BASE_DIR }}/envs/{{ VIRTUAL_ENV_NAME }}/bin"
    patterns: '*supervisor*'
  changed_when: False

- name: Copy supervisord.conf file
  ansible.builtin.template:
    src: supervisord.conf.j2
    dest: "{{ SUPERVISORD_CONFIG_FILE }}"
    mode: '0600'
    force: yes
    backup: yes
    remote_src: no

- name: Create a directory if it does not exist
  ansible.builtin.file:
    path: "{{ item }}"
    state: directory
    mode: '0755'
  with_items:
    - /etc/supervisord.d
    - "{{ SUPERVISOR_BASE_DIR }}"
    - "{{ SUPERVISOR_BASE_DIR }}/pid"
    - "{{ SUPERVISOR_BASE_DIR }}/logs"
    - "{{ SUPERVISOR_BASE_DIR }}/socket"

- name: Copy supervisor test app config
  ansible.builtin.copy:
    src: app.ini
    dest: /etc/supervisord.d/app.ini
    force: yes
    backup: yes
    remote_src: no

- name: Copy supervisor service file
  ansible.builtin.template:
    src: supervisord.service.j2
    dest: /usr/lib/systemd/system/supervisord.service
    force: yes
    backup: yes
    remote_src: no

- name: Start service supervisord, in all cases
  ansible.builtin.service:
    name: supervisord
    state: restarted
    # 开机启动
    enabled: yes

此处需要注意的是，通过ansible_python_interpreter变量来指定远程主机上的python解释器路径，避免使用默认的python解释器。

像前面任务二一样，修改roles/supervisor/tasks/main.yml配置文件，将前面两个测试好的任务关掉：

yaml

---
# supervisor角色任务
# 安装mincoda
#- include: miniconda.yaml
# 创建虚拟环境
#- include: virtual_env.yaml
# 配置supervisor进程管理工具
- include: supervisor.yaml
# 创建快捷命令
#- include: alias.yaml

然后执行剧本：

[root@ansible ansible_playbooks]# ansible-playbook -i hosts.ini supervisor.yml -v
Using /etc/ansible/ansible.cfg as config file

执行过程截图：

可以看到，任务正常完成，中间创建supervisor相关目录和复制配置文件，由于我之前测试过，文件已经复制到远程主机上了或者文件夹已经创建过了，所以执行过程中显示任务未产生变更。最后一个任务Start service supervisord, in all cases可以看到，supervisord服务正常启动了。

我们在节点1上面检查一下：

[root@ansible-node1 ~]# systemctl status supervisord

testapp                          RUNNING   pid 2349, uptime 0:04:27
[root@ansible-node1 ~]#

可以看到，supervisord服务正常启动了，由其管理的testapp应用也正常启动了，说明supervisor进程管理工具配置正常。

到此，跟supervisor相关的配置就差不多完成了，但每次查看supervisor进程管理工具管理的应用状态，都需要输入那么长的命令，如/srv/miniconda3/envs/supervisorPython3.10.13/bin/supervisorctl status，将显得有点麻烦，因此，就应该为这些命令配置一些快捷命令，这就是下一个任务创建快捷命令的由来。

2.11 任务四-创建快捷命令

创建快捷命令的任务，由roles/supervisor/tasks/alias.yaml定义，查看该文件内容：

yaml

---
- name: Copy alias config
  ansible.builtin.template:
    src: alias_supervisor.sh.j2
    dest: /root/.alias_supervisor.sh
    force: yes
    backup: yes
    remote_src: no

- name: Insert block to .bashrc
  ansible.builtin.blockinfile:
    path: /root/.bashrc
    block: |
      source ~/.alias_supervisor.sh
    create: yes
    # 注意，需要设置不同的marker标记，否则会修改以前存在的默认标记
    marker: "# {mark} meizhaohui add supervisor alias"
    state: present

此任务将自定义的相关快捷命令都写到/root/.alias_supervisor.sh这个文件里面，然后在/root/.bashrc中加载这个文件。

查看alias_supervisor.sh.j2模板内容：

# meizhaohui add this
# supervisor相关的快捷命令
alias supervisordStatus='systemctl status supervisord'
alias supervisordRestart='systemctl restart supervisord'
alias spctl='{{ SUPERVISORD_DIR_PATH }}/supervisorctl'
alias spreload='{{ SUPERVISORD_DIR_PATH }}/supervisorctl reload'
alias spstatus='sp_status'
function sp_status() {
    {{ SUPERVISORD_DIR_PATH }}/supervisorctl status $1|awk '{if($2=="RUNNING"){printf "\033[1;32m"$0"\033[0m\n"} else if($2=="STOPPED"){printf "\033[1;33m"$0"\033[0m\n"} else {print "\033[1;31m"$0"\033[0m"} }'
}

像前面任务一样，修改roles/supervisor/tasks/main.yml配置文件，将前面三个测试好的任务关掉：

yaml

---
# supervisor角色任务
# 安装mincoda
#- include: miniconda.yaml
# 创建虚拟环境
#- include: virtual_env.yaml
# 配置supervisor进程管理工具
#- include: supervisor.yaml
# 创建快捷命令
- include: alias.yaml

然后执行剧本：


[root@ansible ansible_playbooks]# ansible-playbook -i hosts.ini supervisor.yml -v

执行过程截图：

可以看到，supervisor相关的快捷命令都能正常使用了，说明创建快捷命令这个子任务也能正常工作了！！

2.12 复查所有任务

我们测试时，是将测试好的任务注释掉了，再来进行测试的，为了验证整个剧本能正常工作，我们应将之前注释掉的任务现次取消注释，让剧本正常执行。

修改roles/supervisor/tasks/main.yml配置文件，将所有注释的任务打开：

yaml

---
# supervisor角色任务
# 安装mincoda
- include: miniconda.yaml
# 创建虚拟环境
- include: virtual_env.yaml
# 配置supervisor进程管理工具
- include: supervisor.yaml
# 创建快捷命令
- include: alias.yaml

然后执行剧本：

[root@ansible ansible_playbooks]# cat roles/supervisor/tasks/main.yml
---
# supervisor角色任务
# 安装mincoda
- include: miniconda.yaml
# 创建虚拟环境
- include: virtual_env.yaml

执行剧本报错了！！

异常信息：ERROR: File or directory already exists: '/srv/miniconda3'\nIf you want to update an existing installation, use the -u option.

提示目录/srv/miniconda3已经存在，如果你需要更新现有安装，请使用-u参数。

原因是，我们之前测试时，已经将miniconda安装在/srv/miniconda3目录了。并且在上一节已经看到，由miniconda安装的supervisor还在正常管理应用。

我们在节点1上面查看一下miniconda安装程序的帮助信息：

[root@ansible-node1 ~]# cd /tmp/
[root@ansible-node1 tmp]# ./Miniconda3-py310_24.1.2-0-Linux-x86_64.sh  -h

usage: ./Miniconda3-py310_24.1.2-0-Linux-x86_64.sh [options]

Installs Miniconda3 py310_24.1.2-0

-b           run install in batch mode (without manual intervention),
             it is expected the license terms (if any) are agreed upon
-f           no error if install prefix already exists
-h           print this help message and exit
-p PREFIX    install prefix, defaults to /root/miniconda3, must not contain spaces.
-s           skip running pre/post-link/install scripts
-m           disable the creation of menu items / shortcuts
-u           update an existing installation
-t           run package tests after installation (may install conda-build)

[root@ansible-node1 tmp]#

可以看到，miniconda安装程序的确是有一个-u参数。

为了让Ansible在知道有/srv/miniconda3目录时，不执行这个安装任务，则需要修改一下角色的任务。

刚好command模块，有一个creates参数可以来判断目录是否存在，存在就不执行命令。详细可参考 Command命令模块

修改一下角色任务一roles/supervisor/tasks/miniconda.yaml的配置：

yaml

    cmd: "/tmp/{{ MINICONDA_SHELL_FILENAME }} -b -p {{ MINICONDA_BASE_DIR }}"
    # 如果对应的文件存在，则忽略此步
    creates: "{{ MINICONDA_BASE_DIR }}"

- name: Remove install shell file
  ansible.builtin.file:
    path: "/tmp/{{ MINICONDA_SHELL_FILENAME }}"
    state: absent

其中，第40-41行是新增的内容。

此时，再次执行剧本：

[root@ansible ansible_playbooks]# ansible-playbook -i hosts.ini supervisor.yml -v

可以看到任务都执行成功了，然后在节点1上面再检查一下supervisor管理的应用：

可以看到supervisord服务被重启了，并且管理的testapp应用也重启了。说明重复执行Ansible剧本后，节点上的配置仍然是正确的。

说明一个节点任务没有问题了。

再把主机清单里面其他两个节点的注释也关掉，同时在三个节点时执行。

[root@ansible ansible_playbooks]# cat hosts.ini
[supervisorhosts]
192.168.56.121 hostname=ansible-node1
192.168.56.122 hostname=ansible-node2
192.168.56.123 hostname=ansible-node3

由于三个节点同时执行的话，日志比较多，不便于截图，此处执行剧本时，去掉-v参数，执行命令：

[root@ansible ansible_playbooks]# ansible-playbook -i hosts.ini supervisor.yml

可以看到，三个节点都顺利执行完成了。

再在三个节点上面检查一下：

可以看到，三个节点上面supervisord服务正常，管理的testapp也正常工作，说明我们的supervisor角色配置没有问题。

也可以使用登陆一下三个节点的supervisord的web管制台，登陆用的用户名和密码，在默认变量配置文件 roles/supervisor/defaults/main.yml中定义的：

yaml

# 登陆supervisor web控制台的用户名
SUPERVISOR_USERNAME: admin
# 登陆supervisor web控制台的密码
SUPERVISOR_PASSWORD: admin@123

登陆后，可以正常看到supervisor管理的应用：

到此，supervisor角色的相关介绍就结束了！^_^

篇外话：

一旦学会了角色如何配置，你就可以像搭积木一样来使用角色，将角色拆分成多个子任务，然后再单独用Ansible的模块来实现子任务的功能，最后再将各子任务拼接起来，最后你的角色剧本就配置好了，后面就可以方便快速的完成自己的工作了！
