使用playbook部署lamp环境
Playbook常用文件夹作用：
files：存放需要同步到异地服务器的源码文件及配置文件；
handlers：当服务的配置文件发生变化时需要进行的操作，比如：重启服务，重新加载配置文件；
meta：角色定义，可留空；
tasks：需要进行的执行的任务； #任务
templates：用于执行lamp安装的模板文件，一般为脚本；
vars：本次安装定义的变量
安装lamp环境
[root@server ansible]# yum install httpd mariadb-server php php-mysql -y
[root@server ansible]# mkdir /data
[root@server ansible]# chown -R mysql:mysql /data/
[root@server ansible]# vim /etc/my.cnf
[mysqld]
datadir=/data
[root@server ansible]# systemctl start mariadb
创建一个测试页
[root@server ansible]# vim /var/www/html/index.php
<?php
phpinfo();
?>
[root@server ansible]# systemctl restart httpd
测试：http://192.168.220.138/index.php
配置playbook
[root@server ansible]# mkdir -p /etc/ansible/lamp/roles/{prepare,httpd,mariadb,php}/{tasks,files,templates,vars,meta,default,handlers}
[root@server ansible]# tree /etc/ansible/lamp/
/etc/ansible/lamp/

拷贝配置文件
[root@server ansible]# cp /etc/httpd/conf/httpd.conf lamp/roles/httpd/files/
[root@server ansible]# cp /etc/my.cnf lamp/roles/mariadb/files/
1.构建httpd任务
[root@server ~]# cd /etc/ansible/lamp/roles/httpd/
[root@server httpd]# mv /var/www/html/index.php files/
[root@server httpd]# vim tasks/main.yml
- name: install httpd
yum: name=httpd state=present
- name: provide test page
copy: src=index.php dest=/var/www/html/
- name: provide configuration file
copy: src=httpd.conf dest=/etc/httpd/conf/httpd.conf
notify: restart httpd
[root@server httpd]# vim handlers/main.yml
- name: restart httpd
service: name=httpd enabled=yes state=restarted
2.构建mariadb任务
[root@server ~]# cd /etc/ansible/lamp/roles/mariadb/
- name: install mariadb
yum: name=mariadb-server state=present
- name: mkdir data DIR
shell: mkdir /data
- name: provide configuration files
copy: src=my.cnf dest=/etc/my.cnf
- name: change privileges
shell: chown -R mysql:mysql /data/
- name: start mariadb
service: name=mariadb enabled=yes state=started
3.构建php任务
[root@server ~]# cd /etc/ansible/lamp/roles/php/
[root@server php]# vim tasks/main.yml
- name: install php
yum: name=php state=present
- name: install php-mysql
yum: name=php-mysql state=present
4。定义site.yml
[root@server ~]# cd /etc/ansible/lamp/roles/
[root@server roles]# ls
httpd mariadb php prepare
- name: build LAMP
remote_user: root
hosts: client
roles:
- mariadb
- php
- httpd
[root@server roles]# ansible-playbook -i /etc/ansible/hosts ./site.yml
