創建劇本
構建思路，生成目錄樹

初期準備
1、創建好目錄文件
[[email protected] ansible]# mkdir roles/{mariadb/{files,tasks},mariadb_streng{files,tasks}}
2、將下載好的mariadb壓縮包放在角色目錄files下，以便ansible服務器可以通過copy模塊拷貝到客戶端安裝必要的包，避免出錯：early.yml
[[email protected] mariadb]# cat tasks/early.yml
- name: on the early
yum: name=expect,libaio創建組：group.yml
[[email protected] mariadb]# cat tasks/group.yml
---
# Group mysql
- name: Group
group: name=mysql gid=336 system=yes創建用戶：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解壓：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創建硬鏈接：link.yml
[[email protected] mariadb]# cat tasks/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變量：path.yml
[[email protected] mariadb]# cat tasks/path.yml
- name: PATH
shell: echo PATH=/usr/local/mysql/bin:$PATH >/etc/profile.d/mysql.shPATH變量生成：source.yml
[[email protected] mariadb]# cat tasks/source.yml
- name: source
shell: source /etc/profile.d/mysql.sh準備數據庫數據目錄：dir.yml
[[email protected] mariadb]# cat tasks/dir.yml
- name: directory
file: path=/data/mysql state=directory owner=mysql group=mysql生成數據目錄：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
