基于Jenkins集成Ansible与Gitlab实现高可用环境下Wordpress的自动化部署

简介

Jenkins下建立并运行Pipeline Job，从Gitlab主机拉取剧本到Ansible主机，实现Nginx+Keepalived+MySQL+PHP-+Wordpress自动化部署交付；

Jenkins下建立并运行Freestyle Job,从Gitlab主机拉取剧本到Ansible主机,自动部署Zabbix，在Zabbix Web 端配置自动发现进行扫描，监控四台云主机。

Zabbix对高可用集群进行监控：

监控两台Nginx服务器的Nginx并发数、已处理的客户端连接数、客户端请求数等等
监控Web服务器的MySQL数据库的连接数、流量、缓冲池大小与利用率
监控Gitlab服务器的磁盘空间利用率，通过微信进行告警
