简单介绍
Gerrit，谷歌开发的，一种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代码，决定是否能够提交，退回或是继续修改。它使用版本控制系统，Git作为底层。

1. 创建gerrit用户，并进入到/home/gerrit目录中。
adduser gerrit
su gerrit
cd /home/gerrit
2. 安装Gerrit。
wget http://gerrit-releases.storage.googleapis.com/gerrit-2.15.2.war安装中，基本一路回车，但我选择的安全认证方式是HTTP，数据库是H2，并需要配置反向代理
java -jar gerrit-2.6.1.war init -d review_site
apt-get install openjdk-8 git #gerrit依赖git 和java
并配置SMTP
3. 配置Gerrit
Gerrit的配置文件是review_site/etc/gerrit.config我的配置文件：
[gerrit]
basePath = git #git库路径
serverId = 31e19460-4b34-48c5-b0d9-eda02a76315a
canonicalWebUrl = http://192.168.1.10/ #URL
[database]
type = h2
database = /home/gerrit/site_gerrit/db/ReviewDB
[index]
type = LUCENE
[auth]
type = HTTP
[receive]
enableSignedPush = false
[sendemail]
smtpServer = smtp.126.com #配置邮箱
smtpServerPort = 465
smtpEncryption = ssl
smtpUser = [email protected]
smtpPass = xxxxxxxx
sslVerify = false
from=CodeReview<[email protected]>
[container]
user = gerrit
javaHome = /usr/lib/jvm/java-8-openjdk-amd64/jre
[sshd]
listenAddress = *:29418
[httpd]
listenUrl = proxy-http://127.0.0.1:8080/ #这个地方是代理地址
[cache]
directory = cache
[gitweb] #安装gitweb ，可以在网页查看git库目录
type = gitweb
cgi = /usr/share/gitweb/gitweb.cgi3. 安装apache2 服务器
apt-get install apache2
注意:To run Gerrit behind an Apache server using 'mod_proxy', enable the necessary
Apache2 modules:
执行:sudo a2enmod proxy_http
执行:sudo a2enmod ssl
使新的配置生效，需要执行如下命令:
service apache2 restart
5. apache2配置反向代理，
以下部分追加在/etc/apache2/apache2.conf<VirtualHost *:80>
ServerName 192.168.1.10
ProxyRequests Off
ProxyVia Off
ProxyPreserveHost On
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
<Location /login/>
AuthType Basic
AuthName "Gerrit Code Review"
Require valid-user
AuthBasicProvider file
AuthUserFile /home/gerrit/site_gerrit/etc/gerrit.passwd
</Location>
AllowEncodedSlashes On
ProxyPass / http://127.0.0.1:8080/ #这两个地方一定要与gerrit.conf文件中的代理地址一样
ProxyPassReverse / http://127.0.0.1:8080/
</VirtualHost>7. HTTP验证方式口令维护
touch /home/gerrit/site_site/etc/gerrit.passwd
htpasswd -b /home/gerrit/site_site/etc/gerrit.passwd admin 123456(管理员)
htpasswd -b /home/gerrit/site_site/etc/gerrit.passwd usr1 123456htpasswd用法
Usage:
htpasswd [-cimBdpsDv] [-C cost] passwordfile username
htpasswd -b[cmBdpsDv] [-C cost] passwordfile username password
htpasswd -n[imBdps] [-C cost] username
htpasswd -nb[mBdps] [-C cost] username password
-c Create a new file.
-n Don't update file; display results on stdout.
-b Use the password from the command line rather than prompting for it.
-i Read password from stdin without verification (for script usage).
-m Force MD5 encryption of the password (default).
-B Force bcrypt encryption of the password (very secure).
-C Set the computing time used for the bcrypt algorithm
(higher is more secure but slower, default: 5, valid: 4 to 31).
-d Force CRYPT encryption of the password (8 chars max, insecure).
-s Force SHA encryption of the password (insecure).
-p Do not encrypt the password (plaintext, insecure).
-D Delete the specified user.
-v Verify password for the specified user.
On other systems than Windows and NetWare the '-p' flag will probably not work.
The SHA algorithm does not use a salt and is less secure than the MD5 algorithm.8. gerrit 开机自启动
在 /etc/rc.local 下追加/home/gerrit/site_gerrit/bin/gerrit.sh start
9. gerrit 集成 gitweb实现网页中查看项目代码
安装gitweb在gerrit.config下添加apt-get install gitweb
[gitweb] type = gitweb cgi = /usr/share/gitweb/gitweb.cgi
1> 在gerrit集成gitweb之后，发现只有我的root用户（gerrit里注册的第一个用户)才能够点gitweb链接正常打开gitweb页面。其他的普通用户点gitweb链接显示404错误，
为项目的用户组增加了对refs/meta/config的read权限，即在read标签中加入注册的用户组即可
