ansible分离部署LNMP

环境说明:

系统 主机名 IP 服务
centos8 ansible 192.168.111.141 ansible主控机
centos8 nginx 192.168.111.142 nginx受控机
centos8 mysql 192.168.111.143 mysql受控机
centos8 php 192.168.111.144 php受控机

1.准备工作

修改默认清单文件位置,构建清单

[root@ansible ~]# vim /etc/ansible/ansible.cfg  inventory = /etc/ansible/inventory [root@ansible ~]# cd /etc/ansible/ [root@ansible ansible]# touch inventory [root@ansible ansible]# vim inventory  [lnmp] nginx ansible_user=root ansible_password=123456 mysql ansible_user=root ansible_password=123456 php ansible_user=root ansible_password=123456  [root@ansible ~]# vim /etc/hosts  192.168.111.142 nginx 192.168.111.143 mysql 192.168.111.144 php  //列出主机 [root@ansible ~]# ansible lnmp --list-hosts   hosts (3):     nginx     mysql     php  //设置密钥连接 [root@ansible ~]# ssh nginx [root@nginx ~]# exit logout [root@ansible ~]# ssh mysql [root@mysql ~]# exit logout [root@ansible ~]# ssh php [root@php ~]# exit logout [root@ansible ~]#   //测试连通性 [root@ansible ~]# ansible lnmp -m ping nginx | SUCCESS => {     "ansible_facts": {         "discovered_interpreter_python": "/usr/libexec/platform-python"     },     "changed": false,     "ping": "pong" } php | SUCCESS => {     "ansible_facts": {         "discovered_interpreter_python": "/usr/libexec/platform-python"     },     "changed": false,     "ping": "pong" } mysql | SUCCESS => {     "ansible_facts": {         "discovered_interpreter_python": "/usr/libexec/platform-python"     },     "changed": false,     "ping": "pong" } 

2.部署nginx

//关闭selinux和防火墙 [root@ansible ~]# ansible nginx -m service -a 'name=firewalld state=stopped enabled=no' [root@ansible ~]# ansible nginx -a 'setenforce 0' [root@ansible ~]# ansible nginx -a "sed -ri 's/^(SELINUX=).*/1disabled/g'/etc/selinux/config"  //创建用户 [root@ansible ~]# ansible nginx -m user -a 'name=nginx system=yes create_home=no shell=/sbin/nologin state=present'  //安装依赖包 [root@ansible ~]# ansible nginx -m yum -a 'name=pcre-devel,openssl,openssl-devel,gd-devel,gcc,gcc-c++,make state=present'  //下载软件包并解压 [root@ansible ~]# ansible nginx -a 'wget http://nginx.org/download/nginx-1.20.2.tar.gz' [root@ansible ~]# ansible nginx -a 'tar -xf nginx-1.20.2.tar.gz'  //进入目录编译安装 [root@ansible ~]# mkdir -p /etc/ansible/scripts/ [root@ansible ~]# cd /etc/ansible/scripts/ [root@ansible scripts]# vim configure.sh #!/bin/bash  cd nginx-1.20.2  ./configure  --prefix=/usr/local/nginx  --user=nginx  --group=nginx  --with-debug  --with-http_ssl_module  --with-http_realip_module  --with-http_image_filter_module  --with-http_gunzip_module  --with-http_gzip_static_module  --with-http_stub_status_module &&   make -j $(grep 'processor' /proc/cpuinfo | wc -l) && make install  root@ansible scripts]# ll total 4 -rw-r--r-- 1 root root 470 Oct 23 22:04 configure.sh [root@ansible scripts]# ansible nginx -m script -a '/etc/ansible/scripts/configure.sh'  //安装完成 [root@ansible ~]# ansible nginx -a 'ls /usr/local/nginx' nginx | CHANGED | rc=0 >> conf html logs sbin  //配置环境变量 [root@ansible ~]# ansible nginx -m shell -a 'echo "export PATH=$PATH:/usr/local/nginx/sbin" > /etc/profile.d/nginx.sh' [root@ansible ~]# ansible nginx -a 'which nginx' nginx | CHANGED | rc=0 >> /usr/local/nginx/sbin/nginx  //启动服务 [root@ansible ~]# vim /etc/ansible/scripts/nginx_service.sh  #!/bin/bash  cat > /usr/lib/systemd/system/nginx.service << EOF [Unit] Description=nginx server daemon After=network.target  [Service] Type=forking ExecStart=/usr/local/nginx/sbin/nginx ExecStop=/usr/local/nginx/sbin/nginx -s stop ExecReload=/bin/kill -HUP $MAINPID  [Install] WantedBy=multi-user.target EOF  systemctl daemon-reload systemctl enable --now nginx  [root@ansible ~]# ansible nginx -m script -a '/etc/ansible/scripts/nginx_service.sh' [root@ansible ~]# ansible nginx -a 'ss -antl' nginx | CHANGED | rc=0 >> State  Recv-Q Send-Q Local Address:Port Peer Address:PortProcess LISTEN 0      128          0.0.0.0:80        0.0.0.0:*           LISTEN 0      128          0.0.0.0:22        0.0.0.0:*           LISTEN 0      128             [::]:22           [::]:*
