2.配置gerrit
修改/home/gerrit2/gerrit_site_http/etc/gerrit.config配置文件

注意下面两个配置项，修改后如下：

[gerrit]
basePath = git
serverId = 6cab8d0c-5b1e-4a65-8696-0d038780b20d
#canonicalWebUrl = http://iZ2zeajrmfwuxekm559go1Z:8080/
canonicalWebUrl = http://172.16.181.80:8080/ #修改 nginx的代理端口

.........

[httpd]
listenUrl = http://*:8080/ # 未改
重启gerrit
[root@pre-srv44 conf]# /home/gerrit2/gerrit_site_http/bin/gerrit.sh restart
Stopping Gerrit Code Review: OK
Starting Gerrit Code Review: OK

修改nginx
[root@pre-srv44 ~]# cd /usr/local/nginx/conf
[root@pre-srv44 conf]# ls
fastcgi.conf fastcgi_params koi-utf mime.types nginx.conf scgi_params uwsgi_params win-utf
fastcgi.conf.default fastcgi_params.default koi-win mime.types.default nginx.conf.default scgi_params.default uwsgi_params.default
[root@pre-srv44 conf]# cp nginx.conf nginx.conf.bak20180624
[root@pre-srv44 conf]# vi /usr/local/nginx/conf/nginx.conf
...
server {
listen 80;
...
location / {
auth_basic "Gerrit Code Review";
auth_basic_user_file /home/gerrit2/gerrit_site_http/etc/passwords;
proxy_pass http://172.16.181.80:8080;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header Host $host;
}
...

创建认证权限（也就是登陆的时候输入的权限）

注意：第一次加-c参数是为了创建密码文件，默认第一个用户是系统管理员

[root@pre-srv44 etc]# htpasswd -c /home/gerrit2/gerrit_site_http/etc/passwords gerrit2
-bash: htpasswd: command not found
[root@pre-srv44 etc]# yum install htpasswd
Loaded plugins: security

[root@pre-srv44 etc]# ls

[root@pre-srv44 etc]# htpasswd /home/gerrit2/gerrit_site_http/etc/passwords sisi
New password:
Re-type new password:
Adding password for user sisi

3.重启nginx

[root@pre-srv44 etc]# /usr/local/nginx/sbin/nginx -s reload

浏览器登录 http://172.16.181.80/
弹出认证对话框，填写gerrit2登录
An error occurred.
Sorry, the page you are looking for is currently unavailable.
Please try again later.

If you are the system administrator of this resource then you should check the error log for details.

Faithfully yours, nginx.

[root@pre-srv44 logs]# pwd
/usr/local/nginx/logs
[root@pre-srv44 logs]# ls
access.log error.log nginx.pid
[root@pre-srv44 logs]# vi error.log
2018/06/24 08:50:23 [crit] 27123#0: *51 open() "/home/gerrit2/gerrit_site2/etc/passwords" failed (13: Permission denied), client: 172.16.200.188, server: localhost, request: "GET /favicon.ico HTTP/1.1", host: "172.16.181.80"
[root@pre-srv44 conf]# ps -ef|grep nginx
root 14711 1 0 Jun23 ? 00:00:00 nginx: master process /usr/local/nginx/sbin/nginx
nobody 27123 14711 0 08:44 ? 00:00:00 nginx: worker process

工作进程用户是nobody
[root@pre-srv44 conf]# setfacl -R -m u:nobody:rx /home/gerrit2

Question：
Sign Out Failure

也许你会发现用gerrit+HTTP认证，通过web登陆后，点击右上角的Sign Out无法登出。要么是依然保持登陆的状态，要么就是直接出错。

不要以为怎么了，其实这是正常现象，以下这段话是从网上看到的：

You are using HTTP Basic authentication. There is no way to tell a browser to quit sending basic authentication credentials, to logout with basicauthentication is to close the Webbrowser.
More info, go to https://stackoverflow.com/questions/4154187/how-to-logout-user-for-basic-http-authentication

增加几个用户
[gerrit2@pre-srv44 etc]$ sudo htpasswd -b passwords newalan newalan
Adding password for user newalan
[gerrit2@pre-srv44 etc]$ sudo htpasswd -b passwords dev1 dev1
Adding password for user dev1
[gerrit2@pre-srv44 etc]$ sudo htpasswd -b passwords dev2 dev2
Adding password for user dev2
[gerrit2@pre-srv44 etc]$ sudo htpasswd -b passwords mgr1 mgr1
Adding password for user mgr1
[gerrit2@pre-srv44 etc]$ sudo htpasswd -b passwords mgr2 mgr2

4.配置邮箱

htpasswd /home/gerrit2/gerrit_site_http/etc/passwords newalan

配置gerrit.config

登录gerrit注册邮箱
邮箱收到注册链接，http://172.16.181.80:8080/#/VE/fPhKd27E0+4hfHzLSaH5Sp1RCuhou853CdvP2Q==$MTAwMDAwMjp6aGFuZmVuZy56aGFuZ0AxNjMuY29t
去掉链接中的8080端口号，再粘贴到地址栏可用

5.安装gitweb

[gerrit2@pre-srv44 ~]$ sudo yum install -y gitweb
gitweb安装后的目录路径是/var/www/git

git config --file /home/gerrit2/gerrit_site_http/etc/gerrit.config gitweb.cgi /var/www/git/gitweb.cgi
git config --file /home/gerrit2/gerrit_site_http/etc/gerrit.config --unset gitweb.url

6.公私钥
在gerrit本机上使用下面的命令生成管理员账号（这里将gerrit作为管理员）的公私钥
[gerrit2@pre-srv44 .ssh]$ ssh-keygen -t rsa -C "GerritAdmin" -f ~/.ssh/gerritadmin
Generating public/private rsa key pair.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/gerrit2/.ssh/gerritadmin.
Your public key has been saved in /home/gerrit2/.ssh/gerritadmin.pub.
The key fingerprint is:
0a:e4:ed:c8:13:68:b3:dc:f5:0a:7e:64:86:78:34:ad GerritAdmin
The key's randomart image is:
+--[ RSA 2048]----+
| |
| |
| .. |
| +o.. |
| +o++o S |
| o.=E*+o |
| o.*+o . |
| . o.. |
| ... |
+-----------------+
[gerrit2@pre-srv44 .ssh]$ ls
admin admin.pub gerritadmin gerritadmin.pub known_hosts

接下来可以设置别名，方便使用ssh连接gerrit
可以直接在gerrit用户家目录（/home/gerrit）下的.bashrc文件里设置
如下别名是登陆gerrit的admin账号下的操作：
alias ssh-gerrit='ssh -p 29418 -i ~/.ssh/gerritadmin 172.16.181.80 -l gerrit2' 【公钥已拷贝到gerrit里，这里用私钥去连】
然后source /home/gerrit2/.bashrc使其生效

[gerrit2@pre-srv44 ~]$ ssh -p 29418 -i ~/.ssh/gerritadmin 172.16.181.80 -l gerrit2

删除/home/gerrit2/.ssh/known_hosts 重试

[gerrit2@pre-srv44 ~]$ ssh-gerrit gerrit gsql

异常：admin does not have "Access Database" capability

解决：使用Administrator登陆，在Projects/Access中Global Capabilities Add Group（Access Database）添加Administrators组，然后点击页面最下的“Save Changes”按钮即可
