7 directories, 29 files初期准备
1、创建好目录文件
[[email protected] ansible]# mkdir roles/{mariadb/{files,tasks},mariadb_streng{files,tasks}}
2、将下载好的mariadb压缩包放在角色目录files下，以便ansible服务器可以通过copy模块拷贝到客户端安装必要的包，避免出错：early.yml
[[email protected] mariadb]# cat tasks/early.yml
- name: on the early
yum: name=expect,libaio创建组：group.yml
[[email protected] mariadb]# cat tasks/group.yml
---
# Group mysql
- name: Group
group: name=mysql gid=336 system=yes创建用户：user.yml
[[email protected] mariadb]# cat tasks/user.yml
---
# User
- name: User
user: name=mysql uid=336 group=mysql system=yes home=/data/mysql shell=/sbin/nologin解压：unpack.yml
[[email protected] mariadb]# cat tasks/unpack.yml
---
# Unpack
- name: Unpack mariadb
unarchive: src=/etc/ansible/roles/mariadb/files/mariadb.tar.gz dest=/usr/local copy=yes创建硬链接：link.yml

---
# Link

[[email protected] mariadb]# cat tasks/owner.yml

# owner group
- name: owner group
file: path=/usr/local/mysql owner=root group=root recurse=yes state=directory添加PATH变量：path.yml
[[email protected] mariadb]# cat tasks/path.yml
- name: PATH
shell: echo PATH=/usr/local/mysql/bin:$PATH >/etc/profile.d/mysql.shPATH变量生成：source.yml
[[email protected] mariadb]# cat tasks/source.yml
- name: source
shell: source /etc/profile.d/mysql.sh准备数据库数据目录：dir.yml
[[email protected] mariadb]# cat tasks/dir.yml
- name: directory
file: path=/data/mysql state=directory owner=mysql group=mysql生成数据目录：data.yml
[[email protected] mariadb]# cat tasks/data.yml
- name: data
shell: /usr/local/mysql/scripts/mysql_install_db --datadir=/data/mysql --user=mysql生成配置文件：config{1,2,3}.yml
[[email protected] mariadb]# cat tasks/config1.yml

[[email protected] mariadb]# cat tasks/config2.yml

[[email protected] mariadb]# cat tasks/config3.yml
