Ansible 部署LNMP

1.环境准备

[wsh@controller ~ ?]$ mkdir LNMP
[wsh@controller ~ ?]$ ls
ansible  LNMP
[wsh@controller ~ ?]$ cp ansible/ansible.cfg ansible/inventory LNMP/
[wsh@controller ~ ?]$ cd LNMP/
[wsh@controller LNMP ?]$ ls
ansible.cfg  inventory[wsh@controller LNMP ✔]$ rz -E
rz waiting to receive.
[wsh@controller LNMP ✔]$ ls
ansible.cfg  inventory  wordpress-4.9.4-zh_CN.zip

  • 准备环境变量

#主机清单
[wsh@controller LNMP ✔]$ cat inventory 
[lnmps]
lnmp ansible_host=node1[controllers]
controller[dev]
node1[test]
node2[prod]
node3
node4
# ansible 配置
[wsh@controller LNMP ✔]$ cat ansible.cfg 
[defaults]                         
inventory = ./inventory            
remote_user = wsh                 
vault_password_file=./secret.txt   [privilege_escalation]             
become=True                        
become_method=sudo                 
become_user=root                   
become_ask_pass=False[wsh@controller LNMP ✔]$ cat secret.txt 
redhat

2.准备Maria DB

1.变量配置

[wsh@controller LNMP ✔]$ mkdir -p host_vars/lnmp
[wsh@controller LNMP ✔]$ cat host_vars/lnmp/vars.yml 
db_name: webapp
[wsh@controller LNMP ✔]$ ansible-vault view host_vars/lnmp/vaults.yml
mysql_root_password: wsh@123
app_user: wordpress
app_password: wsh@123
app_host: '%'
app_priv: '*.*:ALL'
[wsh@controller LNMP ✔]$ vim LNMP-playbook.yml

2.服务的安装启动与安全初始化

---                          
- name: deploy mariadb       hosts: lnmp                tasks:                     #安装                    - name: install mariadb yum:                   name:                - mariadb-server   - python2-PyMySQL  state: present       # 启动                   - name: enabled and start db service:               name: mariadb        enabled: yes         state: started# 设置 root 密码    - name: set root@localhost passwordshell: mysqladmin password {{ mysql_root_password }}ignore_errors: yes - name: set root passwordmysql_user:       name: root       password: "{{ mysql_root_password }}"host: "{{ item }}"state: present  login_user: rootlogin_password: "{{ mysql_root_password }}"with_items:       - "{{ ansible_fqdn }}"- 127.0.0.1     - ::1           # 删除匿名用户        - name: delete user anonymousmysql_user:       name: ""        host_all: yes   state: absent   login_user: rootlogin_password: "{{ mysql_root_password }}"#login_unix_socket: /var/lib/mysql/mysql.sock# 删除测试数据库    - name: delete database testmysql_db:         name: test      state: absent   login_user: rootlogin_password: "{{ mysql_root_password }}"

3.创建用户与数据库

#创建新用户和库
- name: prepare db for webapphosts: lnmp  tasks:       # 创建新用户- name: create user {{ user }}mysql_user:name: "{{ app_user }}"password: "{{ app_password }}"host: "{{ app_host }}"priv: "{{ app_priv }}"state: presentlogin_user: rootlogin_password: "{{ mysql_root_password }}"# 创建新库 - name: create database db_namemysql_db:name: "{{ db_name }}"state: presentlogin_user: root

3.准备nginx

安装和启动服务器

#准备web服务器                                
- name: deploy web server                     hosts: lnmp                                 tasks:- name: install nginx                     yum:                                    name: nginx                           state: present                        #启动服务                                 - name: enabled and started nginx         services:                               name: nginx                           state: started                        enabled: yes                          - name: prepare test page                 copy:                                   content: hello world from nginx       dest: /usr/share/nginx/html/index.html

6.执行ansible

1.测试playbook

[wsh@controller LNMP ✔]$ ansible-playbook LNMP-playbook.yml --syntax-checkplaybook: LNMP-playbook.yml

2.执行测试
