ansible部署lnmp架构
环境准备：
| 主机名 | IP | 服务 | 系统 |
|---|---|---|---|
| ansible | 192.168.160.131 | ansible | CentOS-8.5 |
| nginx | 192.168.160.132 | nginx | CentOS-8.5 |
| mysql | 192.168.160.137 | mysql | CentOS-8.5 |
| php | 192.168.160.139 | php | CentOS-8.5 |
1、生成私钥，对另外三台主机进行免密登入
[root@ansible ~]# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
/root/.ssh/id_rsa already exists.
Overwrite (y/n)? yes
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:Ny1q6A+oJY8ZDV3+eX0hpKzOYWvrtR5/FipNa7DWj+0 root@ansible
The key's randomart image is:
+---[RSA 3072]----+

[root@ansible ~]# ssh-copy-id -i /root/.ssh/id_rsa.pub 192.168.160.132
[root@ansible ~]# ssh-copy-id -i /root/.ssh/id_rsa.pub 192.168.160.137
[root@ansible ~]# ssh-copy-id -i /root/.ssh/id_rsa.pub 192.168.160.139
2.构建Ansible清单
[root@ansible ~]# cd /etc/ansible/
[root@ansible ansible]# vim hosts
//添加受管主机
192.168.160.132
192.168.160.137
192.168.160.139
3. 受管主机安装python3
[root@nginx ~]# yum -y install python3
[root@mysql ~]# yum -y install python3
[root@php ~]# yum -y install python3
4. 管理nginx受管主机部署nginx服务
//创建系统用户nginx
[root@ansible ansible]# ansible 192.168.160.132 -m user -a 'name=nginx system=yes shell=/sbin/nologin state=present'
//安装依赖包
[root@ansible ansible]# ansible 192.168.160.132 -m yum -a 'name=pcre-devel,openssl,openssl-devel,gd-devel,gcc,gcc-c++,make,wget state=present'
//创建日志存放目录
[root@ansible ansible]# ansible 192.168.160.132 -m file -a 'path=/var/log/nginx state=directory'
[root@ansible ansible]# ansible 192.168.160.132 -m file -a 'path=/var/log/nginx state=directory owner=nginx group=nginx'
//下载nginx并解压
[root@ansible ansible]# ansible 192.168.160.132 -m get_url -a 'url=http://nginx.org/download/nginx-1.20.2.tar.gz'
[root@ansible ansible]# ansible 192.168.160.132 -a 'tar xf nginx-1.20.2.tar.gz'
//编写编译脚本，然后进行编译安装
[root@ansible ansible]# mkdir scripts/

[root@ansible ansible]# chmod +x scripts/a.sh
[root@ansible ansible]# ansible 192.168.160.132 -m script -a '/etc/ansible/scripts/a.sh'
[root@ansible ansible]# ansible 192.168.160.132 -m shell -a 'cd nginx-1.20.2 && make && make install '
//配置环境变量
[root@ansible ansible]# ansible 192.168.160.132 -m shell -a 'echo "export PATH=/usr/local/nginx/sbin:$PATH" > /etc/profile.d/nginx.sh'
