整合Gitolite、Jenkins、Gerrit 协同工做

• Gitolite 代码托管
• Gerrit 代码审核
• Jenkins 编译测试
  各个环境的搭建能够参考个人其余几篇文章

在基本环境的基础上，须要用到：

• git hook
• Jenkins 的 Generic Webhook Trigger插件
• Gerrit 的 replication 插件

本例以PostgreSQL项目为例

1.Gerrit

1.1安装 replication 插件
若是安装Gerrit时安装了replication插件，能够忽略这一项。
插件安装：

[gerrit@localhost ~]$ java -jar gerrit-2.12.4.war init -d gerrit_site --batch --install-plugin replication

1.2 建立postgresql项目
该项目事先存在于Gitolite中

[gerrit@localhost git]$ pwd
/home/gerrit/gerrit_site/git
[gerrit@localhost git]$ ssh -p 29418 -i ~/.ssh/id_rsa 192.168.81.186 -l gerrit gerrit create-project postgresql
[gerrit@localhost git]$ ll
total 0
drwxrwxr-x. 7 gerrit gerrit 100 Jan 25 02:56 All-Projects.git
drwxrwxr-x. 7 gerrit gerrit 100 Jan 25 02:56 All-Users.git
drwxrwxr-x. 7 gerrit gerrit 100 Jan 29 04:35 postgresql.git
[gerrit@localhost git]$ rm -rf postgresql.git/
[gerrit@localhost git]$ git clone --bare git@127.0.0.1:postgresql.git
Cloning into bare repository 'postgresql.git'...
remote: Counting objects: 515391, done.
remote: Compressing objects: 100% (78522/78522), done.
remote: Total 515391 (delta 434772), reused 515391 (delta 434772)
Receiving objects: 100% (515391/515391), 151.21 MiB | 6.49 MiB/s, done.
Resolving deltas: 100% (434772/434772), done.

1.3 添加replication.config给gerrit

[gerrit@localhost ~]$ cd gerrit_site/etc/
[gerrit@localhost etc]$ vi replication.config

[remote "postgresql"]
projects = postgresql
url = git@127.0.0.1:postgresql.git
push = +refs/heads/*:refs/heads/*
push = +refs/tags/*:refs/tags/*
push = +refs/changes/*:refs/changes/*
threads = 3

1.4 设置gerrit用户的 ~/.ssh/config

[gerrit@localhost ~]$ sh -c "ssh-keyscan -t rsa 127.0.0.1 >> /home/gerrit/.ssh/known_hosts"
[gerrit@localhost ~]$ sh -c "ssh-keygen -H -f /home/gerrit/.ssh/known_hosts"

1.5.从新启动 Gerrit 服务

[gerrit@localhost ~]$ /home/gerrit/gerrit_site/bin/gerrit.sh restart

2.Jenkins

2.1 安装Generic Webhook Trigger Plugin 插件
系统管理 =》管理插件 =》可选插件
使用过滤功能找到"Generic Webhook Trigger Plugin"插件并安装(因为我已经安装好了，所在不显示出来，能够在已安装找到)


2.2 新建PostgreSQL项目

构建触发器配置项目触发条件，勾选Generic Webhook Trigger，在此使用Request parameters，填写自定义的参数和值

构建 =》Execute shell
简单编写一个clone代码而后编译的动做

git clone git@127.0.0.1:postgresql
cd postgresql
./configure --prefix=$WORKSPACE/pgsql
make 
make install

2.3 获取API Token
在“系统管理–管理用户–用户列表” 点击用户后面的设置图标，获取 API Token

3.Gitolite

添加 hook
进入postgresql项目的hooks目录，添加post-receive,使用curl命令发送post请求

[git@localhost hooks]$ pwd
/home/git/repositories/postgresql.git/hooks
[git@localhost hooks]$ touch post-receive
[git@localhost hooks]$ vi post-receive

#!/bin/sh
curl "http://highgo:8703ec11eeea10bb0be850d76c5ef2f7@192.168.81.186:8080/generic-webhook-trigger/invoke?start=1"
# 命令参数说明：http://用户名:API_Token@IP:端口//generic-webhook-trigger/invoke?自定义参数=参数值

[git@localhost hooks]$ chmod +x post-receive

修改项目权限，普通用户不能写入

[git@localhost conf]$ pwd
/home/git/gitolite-admin/conf
[git@localhost conf]$ vi gitolite.conf

repo gitolite-admin
    RW+     =   admin

repo postgresql
    R       =   @all
    RW+     =   admin gerrit

repo testing
    RW+     =   @all

提交修改

[git@localhost conf]$ git add gitolite.conf 
[git@localhost conf]$ git commit -am "change gitolite.conf"
[git@localhost conf]$ git push origin master

4. 测试

用户clone代码，修改远程仓库到gerrit，修改提交

[highgo@localhost Desktop]$ git clone git@127.0.0.1:postgresql
[highgo@localhost Desktop]$ cd postgresql/
[highgo@localhost postgresql]$ touch testfile.txt
[highgo@localhost postgresql]$ git remote rm origin
[highgo@localhost postgresql]$ git remote add origin ssh://highgo@192.168.81.186:29418/postgresql.git
[highgo@localhost postgresql]$ git config user.name highgo
[highgo@localhost postgresql]$ git config user.email highgo@test.com
[highgo@localhost postgresql]$ git config remote.origin.push refs/heads/*:refs/for/*
[highgo@localhost postgresql]$ scp -p -P 29418 highgo@192.168.81.186:hooks/commit-msg .git/hooks/
[highgo@localhost postgresql]$ git add testfile.txt 
[highgo@localhost postgresql]$ git commit -am "add testfile.txt"
[highgo@localhost postgresql]$ git push

gerrit审核提交并经过
git通知Jenkins执行项目的编译安装 到此完成了简单的整合工做 (在用户提交到gerrit的时候，也会触发hook，审核经过再次触发，也就是说Jenkins会执行两次，有待解决)
