Introduces how to use the last ansible playbook zabbix client installation (https: / / www. ofstack. com article / 52158. htm), the introduction how to use playbook installation mysql under 1.
Here's how to install mysql:
mysql_basedir: /data/mysql/basedir Source directory
mysql_datadir: /data/mysql/datadir The data directory
mysql_user: mysql mysql The user
mysql_database_user: root Database user
mysql_passwd: 'E4yR3WnoluSFTCBAI' Database password
mysql_port: 3306 mysql Listen on port
mysql_sock: /data/mysql/datadir/mysql.sock mysql the sock
mysql_charset: utf8 mysql Character set
mysql_collation: utf8_general_ci mysql The sorting way
mysql_version: Percona-Server-5.5.21-rel25.1.tar.gz mysql version
Below is the playbook structure to install mysql
10:24:06 # tree mysql_*

12 directories, 15 files
playbook's mysql is installed on

- hosts: "{{host}}"
remote_user: "{{user}}"
gather_facts: True

playbook's mysql assisted

Since installing the zabbix client covered the structure in the previous article, I won't cover it now.

If you want to use my example, can download it from baidu cloud address (file is more than 50 M, can't on the attachment or 51 download center) address is http: / / pan baidu. com/mgG8jY4 s / 1, and then on the/etc ansible directory, the following is the content in the package
