1、前言
Gerrit 名声已很大了，我也就不在过多阐述介绍了，凡是需要安装搭建 Gerrit 服务器的，网上一搜索都是大把精彩教程。但是，基本都是基于代理服务的搭建安装，一种是基于 apache+gerrit 代理的配置，一种是基于 nginx+gerrit 代理的配置，我之前发布的好几篇关于Gerrit 服务的搭建，都有详细的介绍分享，需要的都可以回顾去看看，本文介绍的是 Gerrit 自身带的服务 jetty 服务配置。
2、系统平台
操作系统：Ubuntu 22.04.1 LTS (GNU/Linux 5.15.0-52-generic x86_64)
搭建服务之前，还是老规矩，要先执行系统更新，执行如下两条指令：
$ sudo apt update
$ sudo apt -y upgrade
3、下载
官方下载地址： https://www.gerritcodereview.com/3.6.html
指令下载方式如下图所示：
#下载指令
$ wget https://gerrit-releases.storage.googleapis.com/gerrit-3.6.3.war
查看 JDK 版本
$ java -version
java version "17.0.5" 2022-10-18 LTS
Java(TM) SE Runtime Environment (build 17.0.5+9-LTS-191)
Java HotSpot(TM) 64-Bit Server VM (build 17.0.5+9-LTS-191, mixed mode, sharing)
$
4、开始安装
执行安装指令： $ java -jar gerrit-3.6.3.war init -d /home/scmroot/review_path
如下图所示完整的执行过程
完整代码片段如下：
$ java -jar gerrit-3.6.3.war init -d /home/scmroot/review_path

安装完成后，进入安装目录，查看启动的 log 信息，显示如下信息：
可以看到有报错地方，导致gerrit服务没有启动成功。

关键报错是 ： Caused by: java.io.IOException: Failed to bind to /0.0.31.144:8080 ，，本机的 IP 地址配置有错。
5、修改配置文件
进入etc目录下，修改关键的 gerrit.config 文件，大致修改如下：
修改成正确的 IP 地址，就可以重新执行启动 gerrit 服务了。
sh ../bin/gerrit.sh start
查看 log 日志，没有明细报错，说明配置修改正确，gerrit 服务正常启动了。
打开浏览器访问 gerrit 系统
可以看到 gerrit 首页已正常显示了，注册一个账号，就可以登录系统，正常使用了。
使用 SCM 用户登录后，创建一个 demo 仓库。
查看到 Plugins 信息，就是安装的 v3.6.3 版本对应的插件。
到此，最新版 Gerrit 3.6.3 版本，不适用代理服务的搭建配就分享结束了，希望对各位有所帮助，请给个红心点个赞，谢谢各位。
