一、playbooks 分布式部署 LNMP

1. 環(huán)境配置

ansible服務(wù)器    192.168.145.15
nginx  服務(wù)器    192.168.145.30
mysql  服務(wù)器    192.168.145.45
php    服務(wù)器    192.168.145.60

2. 安裝 ansble

#管理端安裝 ansible
yum install -y epel-release			#先安裝 epel 源
yum install -y ansible

#配置密鑰對驗證
ssh-keygen -t rsa
vim /etc/ssh/ssh_config
-----35行，取消注釋-----
StrictHostKeyChecking nosshpass -p '123' ssh-copy-id root@192.168.145.30
sshpass -p '123' ssh-copy-id root@192.168.145.45
sshpass -p '123' ssh-copy-id root@192.168.145.60

#配置主機(jī)清單
cd /etc/ansiblevim hosts       
[nginx]		
192.168.145.30	
[mysql]
192.168.145.45
[php]
192.168.145.60

#創(chuàng)建一個目錄用來存放 playbooks 的文件
cd /etc/ansible/
mkdir playbooks

3. 安裝 nginx

3.1 準(zhǔn)備 nginx 相關(guān)文件

[nginx-stable]
name=nginx stable repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=1
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true[nginx-mainline]
name=nginx mainline repo
baseurl=http://nginx.org/packages/mainline/centos/$releasever/$basearch/
gpgcheck=1
enabled=0
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true

#準(zhǔn)備nginx源，進(jìn)行yum安裝
cd /opt/
mv nginx.repo /etc/ansible/playbooks/
cd /etc/ansible/playbooks/

#配置 nginx 支持 PHP 解析
cd /etc/nginx/conf.dvim default.conflocation / {root   /usr/share/nginx/html;index  index.php index.html index.htm;}
......location ~ \.php$ {root           html;fastcgi_pass   192.168.145.60:9000;fastcgi_index  index.php;fastcgi_param  SCRIPT_FILENAME  /usr/share/nginx/html$fastcgi_script_name;  # $document_root 和 root 屬性一樣include        fastcgi_params;}cp default.conf /etc/ansible/playbooks/default.conf.j2

#準(zhǔn)備php文件
vim /etc/ansible/playbooks/index.php
<?php
phpinfo();
?>
#測試mysql是否能連接成功
vim /etc/ansible/playbooks/test.php
<?php
$link=mysqli_connect('192.168.145.45','root','Admin@123');
if($link) echo "<h1>Success!!</h1>";
else echo "Fail!!";
?>

3.2 編寫 lnmp.yaml 的 nginx 部分

vim lnmp.yaml
- name: nginx playhosts: nginxremote_user: roottasks:- name: disable selinuxcommand: '/sbin/setenforce 0'ignore_errors: true- name: disable firewalldservice: name=firewalld state=stopped- name: copy nginx yum repo filecopy: src=nginx.repo  dest=/etc/yum.repos.d/- name: install nginxyum: name=nginx state=latest- name: copy index.phpcopy: src=index.php  dest=/usr/share/nginx/html- name: copy nginx template configuration filetemplate: src=default.conf.j2  dest=/etc/nginx/conf.d/default.conf- name: start nginxservice: name=nginx state=started enabled=yes

3.3 測試 nginx

#在ansible服務(wù)器運行
cd /etc/ansible/playbooks/
ansible-playbook lnmp.yaml --syntax-check    #檢查yaml文件的語法是否正確
ansible-playbook lnmp.yaml

#在 nginx 服務(wù)器查看
systemctl status nginx

4. 安裝 mysql

4.1 準(zhǔn)備 mysql 相關(guān)文件

#安裝 mysql 5.7
cd /etc/yum.repos.d
wget -
