ansbile安装:

# ansible在CentOS7中需要安装epel仓库
yum install -y epel-release
yum install -y ansible

安装有好几种方法,yum安装是最简单的,安装ansible不是重点。

我的版本如下:

[root@szwpldb1081 mysqltools]# ansible --version
ansible 2.7.10
  config file = /etc/ansible/ansible.cfg
  configured module search path = [/root/.ansible/plugins/modules, /usr/share/ansible/plugins/modules]
  ansible python module location = /usr/local/python-3.7.3/lib/python3.7/site-packages/ansible
  executable location = /usr/local/python/bin/ansible
  python version = 3.7.3 (default, Dec 15 2019, 15:54:59) [GCC 4.8.5 20150623 (Red Hat 4.8.5-39.0.3)]

我的目录树如下:

以安装单机版为例, install_single.yaml 如下:

[root@szwpldb1081 mysql]# cat install_single.yaml 
---
  - hosts: uat
    remote_user: root
    become_user: root

    template:
      src: "../templates/users.sql"

  - name: "start mysqld-{{mysql_port}}"
    systemd:
      name: "mysqld-{{mysql_port}}"
      state: started
      daemon_reload: yes

定义一些变量配置参数 config.yaml :

[root@szwpldb1081 mysql]# cat ../../config.yaml
max_memory_size_mb: "{{ 1024 * 512 }}" # 512G内存
mysql_port: 33601
mysql_binary_pkg: "mysql-8.0.18-linux-glibc2.12-x86_64.tar.xz"

 mysql.yaml 

[root@szwpldb1081 mysql]# cat ./vars/mysql.yaml
#mysql configure
mysql_user: "mysql"
mysql_group: "mysql"
mysql_uid: "{{mysql_port}}"
mysql_gid: "{{mysql_port}}"
mysql_packages_dir: "/usr/local/mysqltools/sps/mysql/"
mysql_base_dir: "/usr/local/{{ mysql_binary_pkg | replace(‘.tar.gz‘,‘‘) | replace(‘.tar.xz‘,‘‘) }}"
mysql_data_dir: "/database/mysql/node1"
mysql_version: "{{ mysql_binary_pkg | replace(‘.tar.gz‘,‘‘) | replace(‘.tar.xz‘,‘‘) }}"
mysql_root_pwd: xxxx
mysql_monitor_user: xxx
mysql_monitor_pwd: xxxx
mysql_binlog_format: "row"
mysql_xport: "{{ mysql_port + 100 }}"
mysql_mgrport: "{{ mysql_port + 101 }}"
mysql_admin_port: "{{ mysql_port + 102 }}"

 create_my_cnf.yaml 

[root@szwpldb1081 mysql]# cat common/create_my_cnf.yaml
---
  - name: "/etc/my-{{mysql_port}}.cnf for mysql-8.0.x "
    when: mysql_binary_pkg.find(8.0) != -1
    template:
      src: ../templates/8.0/my.cnf
      dest: "/etc/my.cnf"
      owner: "{{mysql_user}}"
      group: "{{mysql_group}}"
      backup: yes

  - name: "/etc/my-{{mysql_port}}.cnf for mysql-5.7.x "
    when: mysql_binary_pkg.find(5.7) != -1
    template:
      src: ../templates/5.7/my.cnf
      dest: "/etc/my.cnf"
      owner: "{{mysql_user}}"
      group: "{{mysql_group}}"
      backup: yes

文件目录设置的比较多,主要是为了配置方便灵活,可以适当的增加,看每个人自己实际的情况来操作就好。

[root@szwpldb1081 mysql]# cat /etc/ansible/ansible.cfg 
[defaults]
host_key_checking = False    #不检测host key
stdout_callback = debug
ANSIBLE_STDOUT_CALLBACK=debug

修改ansible配置文件hosts主机里面的主机,然后与 install_single.yaml:里面的host对应上:

[root@szwpldb1081 ~]# cat /etc/ansible/hosts
[uat]
x.x.x.x ansible_host=x.x.x.x ansible_user=root ansible_ssh_pass=xxxxx ansible_su_pass=xxxxx

执行过程报错:

脚本如下:

[root@SZWPLDB1091 ~]# cat /tmp/mysql/init_mysql_data_dir.sh 
#!/bin/bash

cd /usr/local/mysql-8.0.18-linux-glibc2.12-x86_64

if [ -d /database/mysql/node1 ]
then
    echo "`date`  | datadir has been inited" >> /tmp/mtls8.log
    exit 1;
else
    mkdir -p /database/mysql/33601
    mkdir -p /database/mysql/33601/binlogs
    mkdir -p /database/mysql/33601/undolog
    mkdir -p /database/mysql/33601/relaylogs    
    mkdir -p /database/mysql/33601/tmpdir 
    chown mysql:mysql -R /database/mysql
    chmod 600 /root/.mylogin.cnf
    chmod 777 -R /database/mysql
    ./bin/mysqld --defaults-file=/etc/my.cnf --user=mysql --initialize-insecure --init-file=/tmp/mysql/users.sql
fi

最后排查发现是 --init-file=/tmp/mysql/users.sql 有问题,修改以后然后执行:

至此单机mysql一键安装算是完毕,借鉴了https://galaxy.ansible.com/home,看什么时候能自己整合一个平台,把ansible集成到界面,鼠标点记下,就完成一台机器安装,就好了。

ansible一键安装mysql8.0
