devops

以下所有task功能，都是基于根目录下的hosts文件

基础功能

• nopasswd_machine (打通机器)

• ssh_speed_up (ssh连接加速)

• change_require_tty (关闭sudo远程需要tty执行命令)

• yum_install (yum安装常用的软件)

• stop_firewalld (关闭防火墙)

• change_swap (开关swap)

• close_selinux(关闭安全)

• base(基础集成安装)

  sh run_base.sh

应用

• mysql

  # 下载
  # https://downloads.mysql.com/archives/community/
  # 5.7.30
  # 把mysql的bin文件下载下来放在common role的files目录下重命名为mysql.zip (路径: roles/app/mysql/common/files/mysql.zip)
  1. 编辑 hosts文件，将mysql_M，mysql_S IP地址填入，mysql_S 可以是多个。mysql_S需要指定mastere变量 master_host_ip
  2. 编辑 vars/mysql.yaml文件 设置mysql
  3. 运行playbook
  sh run_app.sh mysql

• nfs

  # 配置 hosts 
  # 服务端: nfs_svr  客户端：nfs_cli

            - {"L5": "6379", "L3": "6378"}
            
            
  sh run_app.sh redis  # 安装redis
  sh run_app.sh redis-replica  # 上面redis的部分命令，建立集群关系
  
  # 单实例
  
  # host配置
  	redis_single:
        hosts:
          L1:
            redisPorts: ["6379"]
        vars:
          redisVersion: redis-6.0.6
          redisInstallDir: /home/data
          
  ansible-playbook -t redis -i inventory/cluster/hosts.yml app.yml -l L1
