公司之前一直用gitlab来存放项目代码 ,目前因为业务需要(代码bug太多)需要引入gerrit来进行code review。

最初用的是centos 7.4,但是安装完成后,GerritResource中没有ALL_Project.git和All_Users.git生成,日志中一直在报错,反复装了几次后发现,在centos7上的兼容性不是太完美,所以采购了centos6.8 服务器进行安装,还是比较顺利的完成了安装。

另外本文采用LDAP认证,LDAP的配置本文不做讲解,参考其他文章。

已经在用:
gitlab-ce-9.3.3-ce.0.el7.x86_64
最新部署:
centos 6.8 x64
gerrit 2.15.6
nginx 1.10.2
mysql 5.6

1、建立专有帐户
$ useradd gerrit -m -s /bin/bash
$ passwd gerrit ##本文密码与用户同名
$ su - gerrit

2、配置 Java 环境

[root@ao-internal02 ~]# java -version
java version "1.8.0_151"
Java(TM) SE Runtime Environment (build 1.8.0_151-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.151-b12, mixed mode)
[root@ao-internal02 ~]# 

3、从官网下载gerrit
https://www.gerritcodereview.com/
当前最新版本为 2.15.6。

4、安装 MySQL

5、创建数据库、用户、授权
这里选择 MySQL 作为 Gerrit 的数据库,其它选项全部采用默认配置。对于这种选择,需要连上 MySQL,为 Gerrit 创建相应的数据库,用户,并为用户授权:

$ mysql -u root -p
Enter password: 
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 35
Server version: 5.7.20-0ubuntu0.16.04.1 (Ubuntu)

Copyright (c) 2000, 2017, Oracle and/or its affiliates. All rights reserved.

owners.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql> SELECT USER();
+----------------+
| USER()         |
+----------------+
| root@localhost |
+----------------+

mysql> create database reviewdb;

mysql> grant all privileges on reviewdb.* to gerrit@localhost identified by 'gerrit';
Query OK, 0 rows affected, 1 warning (0.01 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

mysql> show databases;
+--------------------+

| mysql              |
| performance_schema |
| reviewdb           |
| sys                |
+--------------------+
8 rows in set (0.01 sec)

6、安装gerrit
把包传到gerrit的家目录,修改相关的权限 。通过如下命令安装 Gerrit:

[gerrit@ao-internal02 ~]$ java -jar  gerrit-2.15.6.war  init -d review_site
Using secure store: com.google.gerrit.server.securestore.DefaultSecureStore

*** Gerrit Code Review 2.15.6
*** 

*** Git Repositories
*** 

Location of Git repositories   [GerritResource]: 
**git 代码仓库的位置, 默认会在之前敲的init -d 目录下新建一个GerritResource文件夹,这个选项用于配置 Gerrit 的 Git 仓库的保存地址。上面的配置将创建 /home/gerrit/review_site/GerritResource 目录用于保存 Gerrit 的 Git 仓库。
*** SQL Database
***

Initialized /data/gerrit/review_site
[gerrit@ao-internal02 ~]$ 

##默认安装完后服务是会启动的。

##这里因为有调整,所以手工启动服务了。
[root@ao-internal02 bin]# ./gerrit.sh  start
Starting Gerrit Code Review: OK

监控日志输出:

排错过程:
1、Gerrit 安装过程中,可能会报出如下的 Exception:

这个异常可通过如下方式解决:使用 MySQL root 用户登录,设置

set global explicit_defaults_for_timestamp=1;

像下面这样:

$ mysql -u root -p
Enter password: 
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 76

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql> set global explicit_defaults_for_timestamp=1;
Query OK, 0 rows affected (0.00 sec)

mysql> exit;
Bye

如果数据库是主从,一定要在主库上创建库、用户、授权。否则会报错:

解决办法: 在主库上建库、用户、授权。
最终配置文件:

[gerrit@ao-gerrit01 etc]$ more gerrit.config 
[gerrit]
        basePath = GerritResource
        serverId = 5ae3e303-92dc-4823-8284-e21a14034f75
        canonicalWebUrl = http://gerrit.baidu.com/
[database]
        type = mysql
        hostname = localhost
        database = reviewdb
        username = gerrit
[noteDb "changes"]
        disableReviewDb = true
        primaryStorage = note db
        read = true
        sequence = true
        write = true
[index]
        type = LUCENE
[auth]
        type = LDAP
        gitBasicAuthPolicy = LDAP
[ldap]
        server = ldap://101.11.23.191:389
        username = cn=Manager,dc=baidu,dc=com
        accountBase = dc=baidu,dc=com
        groupBase = dc=baidu,dc=com
[receive]
        enableSignedPush = false
[sendemail]
        enable = true
        smtpServer = smtp.exmail.qq.com
        smtpServerPort = 587
        smtpEncryption = TLS
        smtpUser = dr@baidu.com
        smtpPass = 123456
        from = dr@baidu.com
[container]
        user = gerrit
        javaHome = /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.191.b12-0.el6_10.x86_64/jre
[sshd]
        listenAddress = *:29418
[httpd]
        listenUrl = http://*:8080/
[cache]
        directory = cache
[gitweb]
    cgi = /var/www/git/gitweb.cgi
    type = gitweb
[plugins]
        # allow install plugin
        allowRemoteAdmin = true
[gerrit@ao-gerrit01 etc]$ 

后续配置:
1、在/review_gerrit/bin/gerrit.sh中实际代码第一行加入
GERRIT_SITE=/home/gerrit/review_site

例如:

[root@ao-gerrit01 logs]# vim /review_gerrit/bin/gerrit.sh
GERRIT_SITE=/home/gerrit/review_site
#!/bin/sh
  GERRIT_SITE            =  /home/gerrit/review_site

2、全局使用gerrit:
[root@ao-gerrit01 logs]# ln -s /home/gerrit/review_site/bin/gerrit.sh /usr/bin/gerrit
安装插件:

[gerrit@ao-gerrit01 ~]$ ssh -i .ssh/id_rsa -p 29418 gerritadmin@localhost gerrit plugin install -n replication.jar -  < gerrit-2.15.6/WEB-INF/plugins/replication.jar  
fatal: remote installation is disabled
[gerrit@ao-gerrit01 ~]$

3、# 安装复制插件

unzip gerrit-2.14.1.war
ssh -p 29418 gerrit_admin_user@localhost gerrit plugin install -n replication.jar - < ./WEB-INF/plugins/replication.jar

#如果安装时提示权限问题,要在gerrit.config 上添加 allowRemoteAdmin 参数,文件见下面

[plugins]
        # allow install plugin
        allowRemoteAdmin = true

重启一下服务

[gerrit@ao-gerrit01 ~]$ gerrit restart
Stopping Gerrit Code Review: OK
Starting Gerrit Code Review: WARNING: Could not adjust Gerrit's process for the kernel's out-of-memory killer.
         This may be caused by /usr/bin/gerrit not being run as root.
         Consider changing the OOM score adjustment manually for Gerrit's PID=6302 with e.g.:
         echo '-1000' | sudo tee /proc/6302/oom_score_adj
OK
[gerrit@ao-gerrit01 ~]$

安装replication

[gerrit@ao-gerrit01 ~]$ ssh -i .ssh/id_rsa -p 29418 gerritadmin@localhost gerrit plugin install -n replication.jar -  < gerrit-2.15.6/WEB-INF/plugins/replication.jar 
[gerrit@ao-gerrit01 ~]$ 
查看
[gerrit@ao-gerrit01 etc]$ ssh -i .ssh/id_rsa -p 29418 gerritadmin@localhost gerrit plugin ls
Warning: Identity file .ssh/id_rsa not accessible: No such file or directory.

[gerrit@ao-gerrit01 etc]$ 

4、Gerrit部署成功后创建项目看不到clone地址
在gerrit部署成功后使用admin账号登录,完成管理员注册流程,然后尝试创建第一个项目。创建项目test,权限继承ALL project,然后进入test,但是看不到clone地址。如下图:
Gitlab+Gerrit+Ldap+nginx+mysql 之Gerrit搭建与配置(一)

解决办法:
安装插件download-commands
Gitlab+Gerrit+Ldap+nginx+mysql 之Gerrit搭建与配置(一)
5、添加key的时候报504
Gitlab+Gerrit+Ldap+nginx+mysql 之Gerrit搭建与配置(一)
解决办法:
确保gerrit.config中,邮箱配置是正确的。另外你的gerrit所在的机器是可以发送邮件的。我这里用的是postfix。配置完后,通过以下命令能收到邮件,即为正常
echo testmail| mail -s "testmail" dragon@baidu.com

6、代码同步到gerrit后,开发者diff不了,一点就报错,很忧伤 。如下图:
Gitlab+Gerrit+Ldap+nginx+mysql 之Gerrit搭建与配置(一)

解决办法 :
nginx配置文件的配置问题:

proxy_pass http://gerrit_server/;
修改为
proxy_pass http://gerrit_server;

 重启nginx服务

7、
Gitlab+Gerrit+Ldap+nginx+mysql 之Gerrit搭建与配置(一)

配置/home/gerrit/review_site/etc/replication.config,没有的话新建:
Gitlab+Gerrit+Ldap+nginx+mysql 之Gerrit搭建与配置(一)

URL这里目前只能写多个了,尝试使用了namespace无效。
就是仓库没办法使用变量,当有新增的话 维护起来比较麻烦,
目前还没有更好的解决办法,哪位大佬给予指导。
