经过一整天的摸索和错误，我想出了种有效的剧本，用于为Laravel应用制作简单的LEMP堆栈。
但是，一切都成功了，但是我仍然对MySQL有麻烦...
服务器安装完毕，开始使用，但是随后我添加了一个数据库和一个用户（并重新启动服务器）。
我将以下内容用作mysql默认值
mysql_packages:
- mysql-server
- mysql-common
- mysql-client
- python-mysqldb
然后我有以下任务脚本：
---
- name: install MySQL packages
apt:
pkg:
"{{ mysql_packages }}"
state: present
update_cache: yes
- name: copy the templates to their respestive destination
template: src={{ item.src }} dest={{ item.dest }} owner=root group=root mode={{ item.mode | default(644) }}
with_items:
- { src: 'my.cnf.j2', dest: '/etc/mysql/my.cnf' }
- { src: 'root.cnf.j2', dest: '~/.my.cnf', mode: '600' }
notify:
- restart MySQL
- name: "Mysql Configuration - Resetting RootPassword"
mysql_user:
name: root
host: "127.0.0.1"
password: "{{ mysql_root_password }}"
check_implicit_admin: yes
login_user: "root"
login_password: "toor"
state: present
- name: Create database user with name '{{ mysql_deploy_user }}' with all database privileges
mysql_user:
name: "{{ mysql_deploy_user }}"
password: "{{ mysql_user_password }}"
priv: '*.*:ALL,GRANT'
state: present
- name: Mysql Configuration - Creating RallyPodium & Reporting Database'
mysql_db:
name: "{{ mysql_database_name }}"
state: present
但是当脚本通过时，它将引发以下内容：
fatal: [staging.rallypodium.be]: FAILED! => {"changed": false, "msg": "Unable to restart service mysql: Job for mysql.service failed because the control process exited with error code.\nSee \"systemctl status mysql.service\" and \"journalctl -xe\" for details.\n"}
当我查看服务器的状态时，我发现服务器根本没有运行，也无法停止，启动，重新启动或重新加载MySQL服务器...
journalctl -xe日志输出如下：
