Gitlab+Jenkins+Nexus 环境搭建

Gitlab代码仓库、Jenkins持续集成、Nexus仓库私服，可以搭配构建一个较完整的开发环境。
根据需求，在CentOS 6.9 系统上搭建以上服务。

Gitlab安装部署

前面的话

源码安装 GitLab 步骤繁琐：需要安装依赖包，Mysql，Redis，Postfix，Ruby，Nginx……安装完毕还得一个个手动配置这些软件。源码安装容易出错，不顺利的话，一天都搞不定。源码最大的好处是私人定制，如果不做定制化，还是使用官方推荐的 omnibus packages 方式安装，网络好的话，一个小时内搞定。

安装环境

系统：CentOS 6.9 64位
内核：2.6.32-696.el6.x86_64

安装前准备

关闭防火墙、关闭selinux

$ service iptables stop
$ vim /etc/selinux/config
    disabled
$ reboot

添加gitlab yum源

$ cd /etc/yum.repos.d/
$ touch gitlab-ce.repo
$ vim gitlab-ce.repo
    [gitlab-ce]
    name=gitlab-ce
    baseurl=http://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el6
    repo_gpgcheck=0
    gpgcheck=0
    enabled=1
    gpgkey=https://packages.gitlab.com/gpg.key
    :wq
$ yum clean all
$ yum makecache

开始安装

安装依赖包

$ yum -y install curl openssh-server openssh-clients postfix cronie
$ service postfix start
$ chkconfig postfix on
$ yum -y install gitlab-ce
It looks like GitLab has not been configured yet; skipping the upgrade script.

Thank you for installing GitLab!

    gitlab-ctl reconfigure

已安装好Gitlab

配置域名访问

添加访问的 host，修改/etc/gitlab/gitlab.rb的external_url

external_url 'http://gitlab.example.com'

vim /etc/hosts
127.0.0.1    gitlab.example.com

gitlab-ctl reconfigure        \\使配置生效

修改本机电脑hosts文件
172.16.16.11 gitlab.example.com

默认账户

账户：root
密码：5iveL!fe

汉化

Gitlab的汉化主要还是需根据安装的版本进行语言包的替换，操作需要灵活性。

$ cat /opt/gitlab/emdedded/service/gitlab-rails/VERSION
10.8.4

$ git clone https://gitlab.com/xhang/gitlab.git
$ ls;cd gitlab
$ git branch -a    #查看当前有哪些版本的汉化包
$ git diff remotes/origin/10-8-stable remotes/origin/10-8-stable-zh > /tmp/10-8.diff
$ gitlab-ctl stop
$ patch -d /opt/gitlab/embedded/service/gitlab-rails -p1 < 10-8.diff
$ gitlab-ctl start
$ gitlab-ctl reconfigure

数据备份

Gitlab的数据备份还是非常有必要的，毕竟都是辛辛苦苦写的代码
默认数据备份目录是/var/opt/gitlab/backups,手动创建备份文件：

• gitlab-rake gitlab:backup:create
• 日常备份，添加crontab

0 2 * * * /opt/gitlab/bin/gitlab-rake gitlab:backup:create CRON=1

数据恢复

• 将数据备份文件拷贝至备份目录

cp 1393513186_gitlab_backup.tar /var/opt/gitlab/backups/

• 停止连接数据库的进程

gitlab-ctl stop unicorn
gitlab-ctl stop sidekiq

• 恢复1393513186这个备份文件，将覆盖GitLab数据库！

gitlab-rake gitlab:backup:restore BACKUP=1393513186

• 启动 GitLab

gitlab-ctl start

• 检查 GitLab

gitlab-rake gitlab:check SANITIZE=true

Gitlab安装完成，可以先登录试试水了

Jenkins安装部署

安装环境

系统：CentOS 6.9 64位
内核：2.6.32-696.el6.x86_64

安装JDK1.8

Jenkins需要jdk1.8的支持，否则会启动失败
下载地址

$ cd /usr/local
$ mv jdk1.8.0_171/ jdk1.8
$ vim /etc/profile
    export JAVA_HOME=/usr/local/jdk1.8
    export PATH=$PATH:$JAVA_HOME/bin
    export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

安装tomcat，配置war包启动

配置tomcat启动Jenkins war包，需要先下载tomcat安装。
下载地址

$ tar -xvf apache-tomcat-8.5.31.tar.gz  -C /usr/local/
        $ mv apache-tomcat-8.5.31/ tomcat-jenkins

默认配置启动Tomcat，访问正常后关闭。下载Jenkins war包
下载地址

$ wget http://mirrors.jenkins-ci.org/war-stable/2.121.1/jenkins.war
$ vim /usr/local/tomcat-jenkins/conf/server.xml
            148       <Host name="localhost"  appBase="/usr/local/tomcat-jenkins/webapps/jenkins"
            149             unpackWARs="true" autoDeploy="true">
            150         <Context path="" docBase="/usr/local/tomcat-jenkins/webapps/jenkins" debug="0" reloadable="true"/>

保存并启动Tomcat，访问地址：http://172.16.16.12:8080/jenkins

Nginx反向代理，实现域名访问
