ansible 配置jspgou商城上线（MySQL版）-编程知识

准备环境

准备两台纯净的服务器进行，在实验之前我们关闭防火墙和selinux

systemctl stop firewalld    #关闭防火墙
setenforce 0        #临时关闭selinux

hosts解析(两台服务器都要去做)

[root@ansible-server ~]# vim /etc/hosts
10.31.162.24    ansible-server
10.31.162.25    ansible-web

安装ansible

10.31.162.24
安装：控制节点1. 配置EPEL网络yum源[root@ansible-server ~]# yum install -y epel*2. 安装ansible[root@ansible-server ~]# yum install -y ansible3.查看版本[root@ansiable-server ~]# ansible --version4.查看配置文件：
[root@ansible-server ~]# rpm  -qc ansible
---1.主配置文件：/etc/ansible/ansible.cfg  #主要设置一些ansible初始化的信息，比如日志存放路径、模块、插件等配置信息
---2.主机清单文件:默认位置/etc/ansible/hosts

安装nginx

# 配置nginx源
[root@ansible-server ~]# vim /etc/yum.repos.d/nginx.repo
[nginx-stable]
name=nginx stable repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=0
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true
# 下载nginx
[root@ansible-server ~]# yum install -y nginx
[root@ansible-server ~]# systemctl start nginx
[root@ansible-server ~]# systemctl enable nginx

上传压缩包

将下载好的jdk、tomcat、jspgou，上传到server机器上
# 也可以直接官网下载
apache-tomcat-9.0.83.tar.gz
jdk-8u321-linux-x64.tar.gz
jspgouV6.1-ROOT.zip# jspgou包是gz的包，需要解压重新压缩才可以用，只能用tar包
[root@ansible-server ~]# yum -y install unzip
[root@ansible-server ~]# unzip jspgouV6.1-ROOT.zip
[root@ansible-server ~]# tar zcvf jspgou.tar.gz DB ROOT
[root@ansible-server ~]# ls
DB ROOT
[root@ansible-server ~]# tar zcvf jspgouv6.1.tar.gz DB ROOT
jspgouv6.1.tar.gz

添加主机

# 添加主机清单
[root@ansible-server ~]# vim /etc/ansible/hosts
[jspgou]
ansible-web# 其他语法
1.添加主机或者主机组：
[root@ansible-server ~]# vim /etc/ansible/hosts  #在最后追加被管理端的机器
ansible-web1                      #单独指定主机，可以使用主机名称或IP地址
2.添加主机组：
[webservers]        #使用[]标签指定主机组 ----标签自定义
192.168.10.11        #如果未解析添加ip
ansible-web2      #解析添加主机名
3.组可以包含其他组：
[webservers1]     #组一
ansible-web1
[webservers2]     #组二
ansible-web2
[weball:children]      #caildren-照写 #weball包括两个子组
webservers1        #组一
webservers2        #组二
4.为一个组指定变量，组内每个主机都可以使用该变量：
[weball:vars]         #设置变量,vars--照写
ansible_ssh_port=22     
ansible_ssh_user=root   
ansible_ssh_private_key_file=/root/.ssh/id_rsa  
#ansible_ssh_pass=1      #也可以定义密码，如果没有互传秘钥可以使用密码。

配置ssh密钥

配置ssh公钥认证：控制节点需要发送ssh公钥给所有非被控制节点
[root@ansible-server ~]# ssh-keygen
[root@ansible-server ~]# ssh-copy-id -i 10.31.126.25  #所有机器

配置剧本

# 在vars目录里配置file.yml配置文件
[root@ansible-server ~]# vim /etc/ansible/vars/file.yml

配置nginx代理

# 备份原有配置文件
[root@ansible-server ~]#  cp default.conf default.conf.bak
# 添加jspgou.conf配置文件
[root@ansible-server ~]#  vim /etc/nginx/conf.d/jspgou.conf 
server {listen       80;server_name  localhost;location / {proxy_pass http://10.31.162.25:8080;proxy_set_header Host $host:$server_port;proxy_set_header X-Real-IP $remote_addr;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;}}
# 重启nginx
[root@ansible-server ~]#  systemctl restart nginx

测试

直接访问代理服务器即可
