CentOs7搭建gitLab

1. 安装并配置依赖，打开防火墙HTTP，SSH链接

yum install -y curl policycoreutils-python openssh-server
systemctl enable sshd
systemctl start sshd
firewall-cmd --permanent --add-service=http
systemctl reload firewalld

注：对于防火墙直接关闭内网防火墙即可，服务器内存至少4G

2. 安装Postfix发信服务器

yum install postfix
systemctl enable postfix
systemctl start postfix

错误： Job for postfix.service failed because the control process exited with error code. See "systemctl st 
解决：修改 /etc/postfix/main.cf的设置  
inet_protocols = ipv4  
inet_interfaces = all 

3. 安装gitLab

下载最新rpm安装：https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7
rpm -i gitlab-ce-10.6.4-ce.0.el7.x86_64.rpm #安装

或镜像安装：
curl -sS http://packages.gitlab.com.cn/install/gitlab-ce/script.rpm.sh | sudo bash
yum install gitlab-ce

4. 修改域名：/etc/gitlab/gitlab.rb文件

external_url 'http://gitlab.mag998.com/' #需添加域名解析
后期可改为：external_url = '127.0.0.1',反正都是反向代理过来的，也都代表一个地址，只是一个外网IP，一个本机，其实一样，用127.0.0.1比较舒服

5. 启动gitLab

gitlab-ctl reconfigure #重置初始化
gitlab-ctl restart #启动

报错ENOMEM：内存至少4G，500等错误，增加内存
free -m #查看swap分区大小
mkdir /swapfile
cd /swapfile
sudo dd if=/dev/zero of=swap bs=1024 count=5000000 #修改count，5G的大小
mkswap -f  swap #转化为swap文件
swapon swap #激活swap文件
free -m #查看大小
swapoff swap #卸载swap分区
/swapfile/swapfile none swap defaults 0 0  #写入/etc/fstab文件

访问报错502：chmod -R 755 /var/log/gitlab

注：关闭原有nginx和tomcat,因为他们会占用80，8080端口，加swap分区后最好重启服务器

6. 正常访问后，修改nginx等的端口配置

1. /etc/gitlab/gitlab.rb文件
unicorn['port'] = 8081
nginx['listen_port'] = 82
gitlab_rails['smtp_enable'] = false #postfix和smtp只能用一个

2. /var/opt/gitlab/gitlab-rails/etc/unicorn.rb文件
listen "127.0.0.1:8081", :tcp_nopush => true

3. /var/opt/gitlab/nginx/conf/gitlab-http.conf文件
listen *:82;

4. /var/opt/gitlab/gitlab-shell/config.yml文件
gitlab_url: "http://127.0.0.1:8081"

5. 重置/重启
gitlab-ctl reconfigure
gitlab-ctl restart

7. 原来的nginx配置均衡代理：

#gitlab server=======start
upstream gitlab {
    server 127.0.0.1:8081;
}
server {
    listen 80;
    server_name gitlab.mag998.com;

    location /{
        client_max_body_size 50m;

        proxy_redirect off;
            
        proxy_set_header Host $host;
        proxy_set_header X-Real_IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            
        proxy_pass http://gitlab;
    }
}
#gitlab end============

8. 常用命令

gitlab-ctl start|stop|status|restart

 9. 解决样式错误问题：

$ cd /
$ cd /opt/gitlab/embedded/service/gitlab-rails
$ apt-get update && apt-get install npm
$ npm install --only=production
$ vim /opt/gitlab/embedded/service/gitlab-rails/config/enviroments/production.rb

- config.serve_static_files = false
+ config.serve_static_files = true

$ gitlab-ctl restart

 10. 汉化

cat /opt/gitlab/embedded/service/gitlab-rails/VERSION #查看现在的gitlab版本
下载汉化包：https://gitlab.com/xhang/gitlab
解压重命名：tar -xzvf xxx.tar.gz / mv gitlab-10-6-stable-zh gitlab
查看汉化包版本：cat /app/gitlab/VERSION

复制替换：
cp -rf /opt/gitlab/embedded/service/gitlab-rails /opt/gitlab/embedded/service/gitlab-rails-bak #备份
\cp -rf  /app/gitlab/*  /opt/gitlab/embedded/service/gitlab-rails/ #加\为不提示overwrite直接覆盖

重新配置和启动
gitlab-ctl reconfigure
gitlab-ctl start

注：样式问题参考上一步

 11. 配置qq邮箱验证

 1. 设置邮箱：/etc/gitlab/gitlab.rb
 gitlab_rails['gitlab_email_from'] = 'maoriaty@foxmail.com'

 gitlab_rails['smtp_enable'] = true
 gitlab_rails['smtp_address'] = "smtp.qq.com"
 gitlab_rails['smtp_port'] = 465
 gitlab_rails['smtp_user_name'] = "maoriaty@foxmail.com"
 gitlab_rails['smtp_password'] = "************" #qq设置账户生成的授权码
 gitlab_rails['smtp_domain'] = "smtp.qq.com"
 gitlab_rails['smtp_authentication'] = "login"
 gitlab_rails['smtp_enable_starttls_auto'] = true
 gitlab_rails['smtp_tls'] = true

 2. 设置IP: /opt/gitlab/embedded/service/gitlab-rails/config/gitlab.yml
 host: gitlab.mag998.com

 3. 配置重启
 gitlab-ctl reconfigure
 gitlab-ctl restart
