今天帮一个同学修改剧本，说是跑不起来服务，中间报错，我就直接修改好放在这，以后供大家浏览看看，虽然写的一般，但是起码功能实现了，哈哈
做该实验起码先把mariadb-10.2.32.tar.gz包下载下来，大概441M。下载链接： wget https://mirrors.tuna.tsinghua.edu.cn/mariadb//mariadb-10.2.32/bintar-linux-x86_64/mariadb-10.2.32-linux-x86_64.tar.gz

编译安装mariadb-10.2.32
1.制作mysql的配置文件

[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

2、编写yml

[root@Centos8-2 ansible]$vim install_mariadb.yml 

---
#Installing MariaDB Binary Tarballs
- hosts: mysql
  remote_user: root
  gather_facts: no

  tasks:
    - name: create group
      group: name=mysql gid=27 system=yes
    - name: create user
      user: name=mysql uid=27 system=yes group=mysql shell=/sbin/nologin home=/data/mysql create_home=no
    - name: mkdir datadir
      file: path=/data/mysql owner=mysql group=mysql state=directory
    - name: unarchive package
      unarchive: src=/data/ansible/files/mariadb-10.2.32.tar.gz dest=/usr/local owner=root group=root
    - name: move
      shell: mv /usr/local/mariadb* /usr/local/mysql
    - name: install database
      shell: scripts/mysql_install_db --datadir=/data/mysql --user=mysql
      args:
        chdir: /usr/local/mysql
    - name: config file
      copy: src=/data/ansible/files/my.cnf dest=/etc/ backup=yes
    - name: service script
      shell: /bin/cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
    - name: start service
      service: name=mysqld state=started enabled=yes
    - name: PATH variable
      copy: content=‘PATH=/usr/local/mysql/bin:$PATH‘ dest=/etc/profile.d/mysql.sh
    - name: source script
      shell: source /etc/profile.d/mysql.sh


4.确认要复制文件的所在路径
[root@Centos8-2 ansible]$ls /data/ansible/files/
install_mariadb.yml  mariadb-10.2.32.tar.gz  my.cnf

编写二进制安装mariadb10.2的ansible-playbook剧本
