saltstack實現數據庫基於GTID的主從複製

安裝pkg部分

[root@server1 pkg]# pwd
/srv/salt/pkg
[root@server1 pkg]# cat install.sls 
pkg-install:
  pkg.installed:
    - pkgs:
      - gcc
      - pcre-devel
      - openssl-devel
      - libxml2-devel
      - libcurl-devel

創建用戶部分

[root@server1 user]# pwd
/srv/salt/user
[root@server1 user]# cat mysql.sls 
mysql-group:
  group.present:
    - name: mysql
    - gid: 1002

mysql-user:
  user.present:
    - name: mysql
    - uid: 1002
    - gid: 1002
    - shell: /sbin/nologin

安裝mysql部分

[root@server1 mysql]# cat install.sls 

include:
  - pkg.install
  - user.mysql


mysql-install:
  pkg.installed:
    - pkgs:
      - mysql-community-client
      - mysql-community-common

      - mysql-community-libs-compat
      - mysql-community-server
    - creates: /usr/local/mysql
    - require:
      - pkg: pkg-install
      - user: mysql-user

主配置文件

[root@server1 files]# pwd
/srv/salt/mysql/files
[root@server1 files]# cat my.cnf
# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html

配置部分

高亮部分爲:從日誌中提取密碼

[root@server1 mysql]# cat service.sls 
include:
  - mysql.install

mysql-password:
  cmd.run:
    - name: /etc/init.d/mysqld start ;cd /var/log  ;passwd=`cat mysqld.log |grep  'temporary password'|awk {'print $NF'}` ;mysql -p$passwd -e "alter user root@localhost identified by 'Zoe++007';" --connect-expired-password
#mysql5.1.7,若是密碼爲明文輸入模式,加參數

    - unless: test -d /var/lib/mysql/mysql

mysql-config:
  file.managed:
    - name: /etc/my.cnf
    - source: salt://mysql/files/my.cnf
    - template: jinja
    {% if grains['fqdn'] == 'server2.lalala.com' %}
    - id: 2
    - GG: log-bin= mysql-bin
    {% elif grains['fqdn'] == 'server3.lalala.com' %}
    - id: 3
    - GG: read-only
    {% endif  %}
   
   #使用jinja模板,給不一樣主機配置不一樣信息


replication-config:
  cmd.run:
    
    {% if grains['fqdn'] == 'server2.lalala.com' %}
    - name: mysql -pZoe++007 -e "grant replication slave on *.* to  miao@'172.25.88.%' identified by 'Zoe++007';" --connect-expired-password

    {% endif  %}
    - unless: test -f /var/lib/mysql/relay-log.info



mysql-init:

  cmd.run:
    - name: chkconfig --add mysqld
    - unless: chkconfig --list mysqld 
    - require:
