Ansible安装mysql
利用playbook安装mysql
下载mysql-5.6.49-linux-glibc2.12到ansible所在的服务器上
https://mirrors.tuna.tsinghua.edu.cn/mysql/downloads/MySQL-5.6/mysql-5.6.49-linux-glibc2.12-x86_64.tar.gz
下载并移动到指定目录下
[root@myserver_1 ~]# wget https://mirrors.tuna.tsinghua.edu.cn/mysql/downloads/MySQL-5.6/mysql-5.6.49-linux-glibc2.12-x86_64.tar.gz

[root@myserver_1 ansible]# cd /data/ansible/files/
[root@myserver_1 files]# mv mysql-5.6.49-linux-glibc2.12-x86_64.tar.gz /data/ansible/files
添加两个配置文件(mysql的配置文件设置)
[root@myserver_1 files]# vim my.cnf
[mysqld]
socket=/tmp/mysql.sock
user=mysql
symbolic-links=0
datadir=/data/mysql
innodb_file_per_table=1
log-bin
pid-file=/data/mysql/mysqld.pid
[client]
port=3306
socket=/tmp/mysql.sock
[mysqld_safe]
log-error=/var/log/mysqld.log
mysql安全加固设置
[root@myserver_1 files]# vim secure_mysql.sh
#!/bin/bash
/usr/local/mysql/bin/mysql_secure_installation <目录结构如下
[root@myserver_1 files]# tree
.
├── my.cnf
├── mysql-5.6.49-linux-glibc2.12-x86_64.tar.gz
└── secure_mysql.sh
0 directories, 3 files
编辑安装mysql的yml文件
[root@myserver_1 files]# vim /root/ansible/install_mysql.yml
- hosts: dbsrvs
remote_user: root
gather_facts: no
tasks:
- name: install packages
yum: name=libaio,perl-Data-Dumper,perl-Getopt-Long

- name: service script
shell: /bin/cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
- name: enable service
shell: /etc/init.d/mysqld start;chkconfig --add mysqld;chkconfig mysqld on
tags: service
- name: PATH variable
copy: content='PATH=/usr/local/mysql/bin:$PATH' dest=/etc/profile.d/mysql.sh
- name: secure script
script: /data/ansible/files/secure_mysql.sh
tags: script
检测语法的正确性(会有报错，因为检测语句不会执行解压，会报mysql的解压后的那个路径存在的问题 可忽略)
[root@myserver_1 ansible]# ansible-playbook -C install_mysql.yml
执行playbook结果如下(有报错信息)
[root@myserver_1 ansible]# ansible-playbook install_mysql.yml
