Gerrit 系统初探 (已转移到 https://steemit.com/gerrit/@linvictor88/gerrit )

Gerrit 使用简介

Gerrit，一种免费、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程序代码，决定是否能够提交，退回或者继续修改。它使用Git作为底层版本控制系统。（from 百度百科）

Gerrit 审核系统搭建过程

创建gerrit2用户

$sudo useradd -m -d /home/gerrit2 -s /bin/bash gerrit2

$sudo su gerrit2

安装mysql以及java环境

略。apt-get

配置mysql

#mysql -u root –p
Mysql>
#CREATE USER 'gerrit2'@'localhost' IDENTIFIED BY 'secret';
#CREATE DATABASE reviewdb;
#ALTER DATABASE reviewdb charset=latin1;
#GRANT ALL ON reviewdb.* TO 'gerrit2'@'localhost';
#FLUSH PRIVILEGES;

下载gerrit并进行初始化

$wget http://gerrit-releases.storage.googleapis.com/gerrit-2.7.war
$java -jar gerrit-2.7.war init -d review_site

参见http://www.infoq.com/cn/articles/Gerrit-jenkins-hudson/
Create '/home/gerrit2/review_site' [Y/n]? Y
Location of Git repositories   [git]:
Database server type           [h2]: mysql

Gerrit Code Review is not shipped with MySQL Connector/J 5.1.21
** This library is required for your configuration. **

更具体是进行初始化

运行gerrit审核系统

$ ./review_site/bin/gerrit.sh start

登录gerrit审核系统官网

默认端口号：8080

修改gerrit界面颜色

默认情况下是纯白色的，不美观可以对 review_site/etc/gerrit.config 修改，然后重启服务，下面是一个颜色配置模板：

[theme]

backgroundColor = FCFEEF

textColor = 000000

trimColor = D4E9A9

selectionColor = FFFFCC

topMenuColor = D4E9A9

changeTableOutdatedColor = F08080

[theme "signed-in"]

backgroundColor = FCFEEF

textColor = 000000

trimColor = D4E9A9

selectionColor = FFFFCC

topMenuColor = D4E9A9

changeTableOutdatedColor = F08080

Gerrit 系统正常测试

  ssh -p 29418 username@webhost 测试gerrit是否正常运行，根据  http://www.infoq.com/cn/articles/Gerrit-jenkins-hudson/ 修改相关ssh配置，成功后会显示如下信息：

**** Welcome to Gerrit Code Review ****

  Hi demo, you have successfully connected over SSH.

  Unfortunately, interactive shells are disabled.

  To clone a hosted Git repository, use:

  git clone ssh://demo@localhost:29418/REPOSITORY_NAME.git

Connection to localhost closed.

Gerrit创建第一个项目

创建项目，克隆病推送代码！

ssh -p 29418 admin@localhost gerrit create-project --name example.git

注意：在gerrit系统上第一个注册的人自动成为管理员，只有管理员才有创建project权限

Github+gerrit+Jenkins(hudson) +redmine

职责：

GitHub is a resource for managing Git code repositories and interacting with other developers. Jenkins is used to continuously test all of the components of OpenStack to ensure functionality and to verify that each change to the code base works as intended. Gerrit is a code review system originally developed for use by the Android Open Source Project and allows us to build a workflow where every change is peer-reviewed and tested by Jenkins before being merged into the main repository.

工作流：

developer checks out source from github.
developer makes changes.
developer pushes to gerrit.
gerrit sends change notice to jenkins for integration test.

jenkins pulls changes directly from gerrit git server.
on pass, jenkins adds +1 to gerrit review, passes review to other developers.
on failure, jenkins adds -1 to gerrit review
pass/fail status pushed to redmine

other developers review change, approve (+2)
gerrit commits changes to github repository.

github hook notifies redmine of updates.
redmine pulls changes from github, parses commit messages for ticket information.

developer fetchs changes from github ... back to 2. [EDIT]: we switched to pulling directly from gerrit. Github remains as a mirror for pulling production sources.
