CentOS7安装GitLab和解决502错误

  • 查询系统发行版本,寻找GitLab对应版本
    $ cat /etc/redhat-release
    CentOS Linux release 7.2.1511 (Core)
    安装过程参考《手把手教你 GitLab 的安装及使用》,RHEL/CentOS用户在rooot权限下,用yum或下载清华大学镜像源:
    新建文件 /etc/yum.repos.d/gitlab_gitlab-ce.repo 内容:
    [gitlab-ce]
    name=Gitlab CE Repository
    baseurl=https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el$releasever/
    gpgcheck=0
    enabled=1
    安装依赖
    #可忽略。CentOS7 卸载旧git,安装新版git
    yum install -y epel-release
    rpm -ivh https://centos7.iuscommunity.org/ius-release.rpm
    yum list git2u
    yum install -y git2u
    git --version
    sudo yum install curl openssh-server openssh-clients postfix cronie -y
    sudo service postfix start
    sudo chkconfig postfix on
    sudo lokkit -s http -s ssh # 这句用于防火墙,避免用户通过ssh方式和http访问。暂未执行
    # 下面是怕redis和nginx没依赖包,提前装了试试
    yum -y install gcc
    yum install tcl
    yum -y install gcc gcc-c++ autoconf automake make
    yum -y install zlib zlib-devel
    yum -y install openssl openssl--devel
    yum -y install pcre pcre-deve
    yum -y install pcre-devel.i686
    yum -y install make zlib zlib-devel gcc-c++ libtool
    安装镜像源
    # yum法
    rm -f /var/run/yum.pid #若yum锁定
    yum list installed | grep gitlab
    yum -y remove gitlab-ce.x86_64 #完全卸载删除gitlab https://yq.aliyun.com/articles/114619
    yum clean all
    sudo yum makecache
    sudo yum install gitlab-ce -y

    # 下载法 centos7版本用el7文件夹,最新版有问题时手动降级
    cd /opt
    wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-10.7.7-ce.0.el7.x86_64.rpm
    chmod 755 gitlab-ce-10.7.7-ce.0.el7.x86_64.rpm
    rpm -ivh gitlab-ce-10.7.7-ce.0.el7.x86_64.rpm

    # 安装完后,将external_url 'http://gitlab.example.com' 改为自己的域名ip,默认8080端口改为 8812
    sudo gedit /etc/gitlab/gitlab.rb

    ---
    external_url 'http://192.168.1.251'
    unicorn['port'] = 8812

    nginx['listen_port'] = 8813
    ---
    # 对GitLab进行初始化配置
    sudo gitlab-ctl reconfigure
    sudo gitlab-ctl reconfigure初始化需等待一段时间,有卡住不动、依赖关系等大问题就删了重装低版本。有gitlab Reconfigured!说明成功。
    注意:执行 reconfigure 命令会把gitlab的nginx组件的配置还原,导致自定义修改的端口以及域名等没有。所以先初始化,再自定义修改。

    自定义修改gitlab并启动
    #外网访问的端口,默认80改为 8813
    sudo gedit /var/opt/gitlab/nginx/conf/gitlab-http.conf
    ---
    server {
    listen 192.168.1.251:8813;
    server_name 192.168.1.251;
    ---

    sudo gedit /var/opt/gitlab/gitlab-rails/etc/unicorn.rb
    listen "192.168.1.251:8812", :tcp_nopush => true

    #设置项目页面中间http地址
    sudo gedit /opt/gitlab/embedded/service/gitlab-rails/config/gitlab.yml
    gitlab:
    ## Web server settings (note: host is the FQDN, do not include http://)
    host: 192.168.1.251
    port: 8813

    #设置项目页面中间ssh地址
    sudo gedit /var/opt/gitlab/gitlab-shell/config.yml
    # Url to gitlab instance. Used for api calls. Should end with a slash.
    gitlab_url: "http://192.168.1.251:8812"


    #增加端口到防火墙配置中,执行以下操作:
    iptables -I INPUT -p tcp --dport 8812 -j ACCEPT
    iptables -I INPUT -p tcp --dport 8813 -j ACCEPT
    iptables -L -n #查看防火墙
    netstat -tln #查看端口

    #重启gitlab,访问http://192.168.1.251:8813
    http://192.168.1.251:8813
    gitlab-ctl restart

    sudo gitlab-ctl restart sidekiq sudo gitlab-ctl hup unicorn gitlab-ctl tail unicorn
    访问gitlab,第一次登陆时设置密码

    gitlab-ctl start|stop|status|restart #管理
    gitlab-ctl restart #重启gitlab
    在restart后,就可以直接访问:http://192.168.1.251:8813 ,默认用户名root,第一次登陆时设置密码。
    若有502问题,修改冲突的端口,或reboot重启试试。
    502太坑了……gitlab集成了各组件,所以要修改各组件具体的ip地址、端口号。
    对于错误,及时查看日志文件和错误文件,如:
    gitlab-shell.log
    gitlab_access.log
    unicorn_stderr.log
    gitlab_error.log
    一般都是127.0.0.1或端口没改过来,即使gitlab网页已经打开,上传东西时也有可能上传组件地址配错,传不上去。

    默认安装的gitlab,主要有四个目录:
    /opt/gitlab/ ## 主目录
    /etc/gitlab/ ## 放置配置文件
    /var/opt/gitlab/ ## 各个组件
    /var/log/gitlab/ ## 放置日志文件

    检查gitlab各组件状态:
    gitlab-ctl status

    重启gitlab:
    gitlab-ctl restart

    只重启某个组件:
    gitlab-ctl restart nginx

    gitlab组件:
    nginx:
    postgresql:
    redis:
    unicorn:
    sidekiq:
    logrotate:

    5 汉化 #可跳过这步

    cd /opt
    wget https://gitlab.com/xhang/gitlab/repository/10-7-stable-zh/archive.tar.bz2 -O gitlab-10-7-stable-zh.tar.bz2
    tar xf gitlab-10-7-stable-zh.tar.bz2
    mv gitlab-10-7-stable-zh-c400d379745573f67a8961f41534bd4653136d8e gitlab-10-7-stable-zh
    cat gitlab-10-7-stable-zh/VERSION

    sudo gitlab-ctl stop
    #先备份,避免汉化失败后gitlab瘫痪
    cp -r /opt/gitlab/embedded/service/gitlab-rails{,.ori}
    \cp -rf gitlab-10-7-stable-zh/* /opt/gitlab/embedded/service/gitlab-rails/
    忽略以下2个提示
    cp: 无法以目录"gitlab-10-7-stable-zh/log" 来覆盖非目录"/opt/gitlab/embedded/service/gitlab-rails/log"
    cp: 无法以目录"gitlab-10-7-stable-zh/tmp" 来覆盖非目录"/opt/gitlab/embedded/service/gitlab-rails/tmp"

    gitlab-ctl reconfigure
    sudo gedit /etc/gitlab/gitlab.rb
    sudo gedit /var/opt/gitlab/nginx/conf/gitlab-http.conf
    gitlab-ctl restart
