Gerrit

1 - 插件管理

1.1 下载并安装插件

以reviewers插件为例。
在GerritForge（https://gerrit-ci.gerritforge.com/），找到对应gerrit 版本的reviewers插件

获得对应的jar下载地址
https://gerrit-ci.gerritforge.com/job/plugin-reviewers-bazel-master/lastSuccessfulBuild/artifact/bazel-bin/plugins/reviewers/reviewers.jar
下载插件（jar包）并放置在$GERRIT_SITE/plugins目录下，然后重启Gerrit服务（$GERRIT_SITE/bin/gerrit.sh restart），会自动加载此目录下的插件。

[gerrit@mt101 ~]$ cd gerrit_testsite/plugins/
[gerrit@mt101 plugins]$ pwd
/home/gerrit/gerrit_testsite/plugins
[gerrit@mt101 plugins]$ wget https://gerrit-ci.gerritforge.com/job/plugin-reviewers-bazel-master/lastSuccessfulBuild/artifact/bazel-bin/plugins/reviewers/reviewers.jar

查看插件是否安装成功

1.2 通过SSH安装插件

实际是通过SSH连接到Gerrit，然后执行“gerrit plugin”命令来管理插件。
官网教程：https://review.gerrithub.io/Documentation/cmd-plugin-install.html

[gerrit@mt101 ~]$ ssh -p 29418 admin@192.168.16.101 gerrit plugin -h
gerrit plugin [COMMAND] [ARG ...] [--] [--help (-h)]
 --          : end of options (default: false)
 --help (-h) : display this help text (default: true)
Available commands of gerrit plugin are:
   add       Install/Add a plugin
   enable    Enable plugins
   install   Install/Add a plugin
   ls        List the installed plugins
   reload    Reload/Restart plugins
   remove    Disable plugins
   rm        Disable plugins
See 'COMMAND --help' for more information.
[gerrit@mt101 ~]$ 
[gerrit@mt101 ~]$ ssh -p 29418 admin@192.168.16.101 gerrit plugin ls

常用的安装方式

# Install a plugin from an absolute file path on the server’s host:
ssh -p 29418 localhost gerrit plugin install -n name.jar $(pwd)/my-plugin.jar
# Install a plugin from an HTTP site:
ssh -p 29418 localhost gerrit plugin install -n name.jar http://build-server/output/our-plugin

1.3 war文件中携带的插件

war文件中包含了一些插件，例如：gerrit-3.1.0.war文件

[gerrit@node202 ~]$ ll

[gerrit@node202 ~]$

2 - 创建用户

2.1 在启用HTTP认证情况下，需要使用htpasswd命令。

示例如下：

[gerrit@mt101 ~]$ chmod 755 /home/gerrit/
[gerrit@mt101 ~]$ 
[gerrit@mt101 ~]$ ll
total 67552
-rw-r--r--  1 gerrit gerrit 69172528 Dec 10 13:04 gerrit-3.1.0.war
drwxr-xr-x 14 root   root        150 Dec 10 14:44 gerrit_testsite
[gerrit@mt101 ~]$ 
[gerrit@mt101 ~]$ sudo htpasswd -c /home/gerrit/gerrit.password admin
New password: 
Re-type new password: 
Adding password for user admin
[gerrit@mt101 ~]$ 
[gerrit@mt101 ~]$ sudo htpasswd -m /home/gerrit/gerrit.password testdemo
New password: 
Re-type new password: 
Adding password for user testdemo
[gerrit@mt101 ~]$ 
[gerrit@mt101 ~]$ sudo chmod 755 gerrit.password 
[gerrit@mt101 ~]$ 
[gerrit@mt101 ~]$ ll
total 67556
-rw-r--r--  1 gerrit gerrit 69172528 Dec 10 13:04 gerrit-3.1.0.war
-rwxr-xr-x  1 root   root         91 Dec 10 14:52 gerrit.password
drwxr-xr-x 14 root   root        150 Dec 10 14:44 gerrit_testsite
[gerrit@mt101 ~]$ 
[gerrit@mt101 ~]$ cat gerrit.password 
admin:$apr1$fQB7h4KA$uhYXP/fEeyfA8GDyA18781
testdemo:$apr1$ETlmCKcz$L5unhKCEx1HRnad7SmPSv.
[gerrit@mt101 ~]$ 
[gerrit@mt101 ~]$ sudo service nginx restart
Redirecting to /bin/systemctl restart nginx.service
[gerrit@mt101 ~]$

2.2 默认认证情况下，可以在web页面添加。

示例如下：

创建新用户

初次登录时，会提醒添加账号的name和email信息。

在User Settings中可以进行具体的设置

3 - 创建新Repository（Project）

4 - SSH连接

4.1 生成SSH公钥

[gerrit@mt101 ~]$ ll .ssh
ls: cannot access .ssh: No such file or directory
[gerrit@mt101 ~]$ 
[gerrit@mt101 ~]$ ssh-keygen -t rsa -C "sshtest"
Generating public/private rsa key pair.
Enter file in which to save the key (/home/gerrit/.ssh/id_rsa): 
Created directory '/home/gerrit/.ssh'.
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /home/gerrit/.ssh/id_rsa.
Your public key has been saved in /home/gerrit/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:9eQRv/j8pNN3N1/7R4KzEvttvg1teyzUbw7Wuyb3YE4 sshtest
The key's randomart image is:
+---[RSA 2048]----+

4.2 在用户设置中添加SSH公钥

这里是在admin账户中添加了SSH公钥

4.3 测试SSH连接

这里通过执行“ssh -p 29418 admin@192.168.16.101 gerrit -h”获取了gerrit的使用帮助信息。
“-p 29418”是指定使用29418端口，在gerrit配置文件中定义了SSH的端口。

[gerrit@mt101 ~]$ ssh -p 29418 admin@192.168.16.101 gerrit -h
The authenticity of host '[192.168.16.101]:29418 ([192.168.16.101]:29418)' can't be established.

5 - 为admin账户开启访问数据库权限

6 - LDAP认证方式

Gerrit支持多种认证方式。
Gerrit可以和LDAP用户认证服务集成，用于用户的导入、同步和集中管理。
在LDAP认证模式下，用户的用户名和密码都是在LDAP端进行管理的。
LDAP认证方式的配置

• Gerrit配置文件auth部分的type属性为LDAP，并增加ldap部分的配置
• 修改nginx配置，将先前的“Basic Auth”相关内容注释，然后重启nginx
