原因及解决方案
 
原因：在不注意的情况下ubuntu更新了mysql软件，而新版的mysql默认开启了ssl。 
解决方案：
 在/etc/mysql/mysql.conf.d/mysqld.cnf文件中的[mysqld] 段下添加skip_ssl 
[mysqld]
# * Basic Settings
user		= mysql
pid-file	= /var/run/mysqld/mysqld.pid
socket		= /var/run/mysqld/mysqld.sock
port		= 3306

				Gerrit，一种免费、开放源代码的代码审查软件，使用网页界面。利用网页浏览器，同一个团队的软件程序员，可以相互审阅彼此修改后的程序代码，决定是否能够提交，退回或者继续修改。它使用Git作为底层版本控制系统。它分支自Rietveld，作者为Google公司的Shawn Pearce，原先是为了管理Android计划而产生。

1、安装jenkins
(1)CentOS7下采用rpm包安装:
wget https://pkg.jenkins.io/redhat/jenkins-2.156-1.1.noarch.rpm
(2)rpm -ivh jenkins-2.156-1.1.noarch.rpm
2、配置端口：vim /etc/sysconfig/jenkins
#监听端口
JENKINS_PORT=“8080”
3、启动：sudo service jenkins restart
ps -ef | g
				1. 前言
最近在摸索git + gerrit代码审核的工作模式，需要安装gerrit服务器，经过一阵折腾，走了不少弯路，在此做下笔记，以便自己或者他人参考。有误的地方请指教。
我的环境如下：
			Windows XP
			192.168.1.100
			客户端web访问...
				如果发现Gerrit地址无法访问：
执行ps -ef | grep apache看一下Apache是否启动，同样看一下MySQL是否启动了，如果都启动着，去gerrit.sh所在目录下 sudo ./gerrit.sh status看一下Gerrit的状态，如果没启动，执行sudo ./gerrit.sh start，提示OK就可以访问了。
操作参考：
如果忘记gerrit.sh在哪个目录了，find一下，
到所在目录执行以下图片操作：
