Ansible实战MySQL安装

先做准备工作，准备一台client，再装备一台master机器。

检查连通性：

  1. [root@ansible-master ~]# ansible mytest -m ping

  2. 10.128.25.175| SUCCESS => {

  3. "ansible_facts": {

  4. "discovered_interpreter_python": "/usr/bin/python"

  5. },

  6. "changed": false,

  7. "ping": "pong"

  8. }

  9. [root@ansible-master ~]#

一.Ansible模块查找使用方法

1.ansible的yum模块查找

yum模块在线文档：https://docs.ansible.com/ansible/latest/collections/ansible/builtin/yum_module.html

示例：

  1. - name: Install the latest version of Apache

  2. yum:

  3. name: httpd

  4. state: latest

  5.  

  6. - name: Install a list of packages (suitable replacement for2.11 loop deprecation warning)

  7. yum:

  8. name:

  9. - nginx

  10. - postgresql

  11. - postgresql-server

  12. state: present

  13.  

  14. - name: Install a list of packages with a list variable

  15. yum:

  16. name: "{{ packages }}"

  17. vars:

  18. packages:

  19. - httpd

  20. - httpd-tools

  21.  

  22. - name: Remove the Apachepackage

  23. yum:

  24. name: httpd

  25. state: absent

2.ansible systemd服务管理模块

systemd模块在线帮助：https://docs.ansible.com/ansible/latest/collections/ansible/builtin/systemd_module.html

示例：

  1. - name: Make sure a service is running

  2. systemd:

  3. state: started

  4. name: httpd

  5.  

  6. - name: Stop service cron on debian, if running

  7. systemd:

  8. name: cron

  9. state: stopped

  10.  

  11. - name: Restart service cron on centos, in all cases, also issue daemon-reload to pick up config changes

  12. systemd:

  13. state: restarted

  14. daemon_reload: yes

  15. name: crond

  16.  

  17. - name: Reload service httpd, in all cases

  18. systemd:

  19. name: httpd

  20. state: reloaded

  21.  

  22. - name: Enable service httpd andensure it isnot masked

  23. systemd:

  24. name: httpd

  25. enabled: yes

  26. masked: no

二.安装MySQL到测试机

  1. [root@ansible-master ~]# ansible test -m yum -a "name=mariadb,mariadb-server state=present"

  2. [root@ansible-master ~]#

三.管理测试机的MySQL服务

1.查看服务启动

  1. [root@ansible-master ~]# ansible mytest -m shell -a "ps -ef | grep mysql |grep -v grep"

  2. 10.128.25.175| CHANGED | rc=0>>

  3. mysql 67071010:58? 00:00:00/bin/sh /usr/bin/mysqld_safe --basedir=/usr

  4. mysql 68696707010:58? 00:00:00/usr/libexec/mysqld --basedir=/usr --datadir=/var/lib/mysql --plugin-dir=/usr/lib64/mysql/plugin --log-error=/var/log/mariadb/mariadb.log --pid-file=/var/run/mariadb/mariadb.pid --socket=/var/lib/mysql/mysql.sock

2.查看mariadb数据库运行情况

  1. [root@ansible-master ~]# ansible mytest -m systemd -a "name=mariadb state=started"

  2. 10.128.25.175| SUCCESS => {

停止服务后再查看：

[root@ansible-master ~]# ansible mytest -m shell -a "ps -ef | grep mysql |grep -v grep"
