ansible-playbook通过github拉取部署Lnmp环境

1. 配置服务器初始化
  1.1) 关闭防火墙和selinux

[root@test-1 ~]# /bin/systemctl stop firewalld
[root@test-1 ~]# /bin/systemctl disable firewalld
[root@test-1 ~]# getenforce                 #查看selinux是否开启
Enforcing                                         #enforcing表示selinux开启的，
[root@test-1 ~]# sed -i 's/SELINUX=enforcing/SELINUX=disabled/g'  /etc/selinux/config      #修改配置文件，需要重启才后永久关闭
[root@test-1 ~]# setenforce 0      #临时关闭selinx
[root@test-1 ~]# getenforce      #查看是否关闭
Disabled

 1.2) 安装epel源

  2.2) 配置ansible的hosts文件
提示：注意以下的配置的hosts文件的IP要根据自己的环境IP配置

[root@test-1 ~]# vim /etc/ansible/hosts 
[root@test-1 ~]# cat /etc/ansible/hosts 
# This is the default ansible 'hosts' file.
#
# It should live in /etc/ansible/hosts
#
#   - Comments begin with the '#' character
#   - Blank lines are ignored
#   - Groups of hosts are delimited by [header] elements
#   - You can enter hostnames or ip addresses
#   - A hostname/ip can be a member of multiple groups
#
# Ex 1: Ungrouped hosts, specify before any group headers.

3. 配置服务器免之间密钥通信
 3.1) 创建免密钥

[root@test-1 ~]# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa): 
Enter passphrase (empty for no passphrase): 
Enter same passphrase again:

Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:lhTKHMoe5UjsWvb3xRHKeQVposFktqZnUONEtq3OEV8 root@test-1
The key's randomart image is:

[root@test-5 ~]# logout
Connection to 192.168.200.135 closed.

提示：
     验证没问题，都可以连接
4. ansible连接是否ping是正常的
  4.1） ansible使用ping，看主机是否正常

[root@test-1 ~]# ansible web1 -m ping
192.168.200.133 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    }, 
    "changed": false, 
    "ping": "pong"
}
192.168.200.132 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    }, 
    "changed": false, 
    "ping": "pong"
}
[root@test-1 ~]# ansible mysql -m ping
192.168.200.135 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    }, 
    "changed": false, 
    "ping": "pong"
}

5. ansible-playbook通常github拉取部署
  5.1) 创建ansible目录

[root@test-1 ~]# mkdir -p /ansible

  5.2) 创建github目录拉取代码

[root@test-1 ~]# mkdir -p /github
[root@test-1 ~]# cd /github/
[root@test-1 github]# ll
total 0

  5.3) 安装git拉取工具

[root@test-1 github]# yum install git -y
[root@test-1 github]# git clone https://github.com/tiaotiaodan/ansible.git
Cloning into 'ansible'...
remote: Enumerating objects: 58, done.

[root@test-1 github]# ll

drwxr-xr-x 5 root root 79 Sep 19 13:28 ansible

5.4) 拷贝ansible-playbook配置文件到/ansible下

[root@test-1 github]# cd ansible/
[root@test-1 ansible]# ll
total 8
drwxr-xr-x 2 root root  17 Sep 19 13:28 group_vars
-rw-r--r-- 1 root root 326 Sep 19 13:28 hosts

-rw-r--r-- 1 root root 323 Sep 19 13:28 site.yaml
[root@test-1 ansible]# cp -a * /ansible/
[root@test-1 ansible]# cd /ansible/
[root@test-1 ansible]# ll
total 8
drwxr-xr-x 2 root root  17 Sep 19 13:28 group_vars
-rw-r--r-- 1 root root 326 Sep 19 13:28 hosts
drwxr-xr-x 7 root root  68 Sep 19 13:28 roles
-rw-r--r-- 1 root root 323 Sep 19 13:28 site.yaml

6. 部署ansible-playbook的lnmp环境
  6.1） 进入ansible目录

[root@test-1 ansible]# cd /ansible/
[root@test-1 ansible]# ll
total 8
drwxr-xr-x 2 root root  17 Sep 19 13:28 group_vars
-rw-r--r-- 1 root root 326 Sep 19 13:28 hosts
drwxr-xr-x 7 root root  68 Sep 19 13:28 roles
-rw-r--r-- 1 root root 323 Sep 19 13:28 site.yaml

  6.2) 检查配置文件

[root@test-1 ansible]# ansible-playbook --syntax-check site.yaml 

playbook: site.yaml

  6.3) 执行配置文件

[root@test-1 ansible]# ansible-playbook site.yaml
