Gitlab搭建安装及使用中遇到的问题。

Posted 2020-10-20 cherry-linux

一、CentOS7安装gitlab-ce

1.下载及安装rpm软件包。

下载RPM包

curl -LJO https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-8.9.8-ce.0.el7.x86_64.rpm

安装RPM包

rpm -i gitlab-ce-8.9.8-ce.0.el7.x86_64.rpm

2.修改Gitlab配置文件。

vim /etc/gitlab/gitlab.rb

external_url 'http://gitlab.federico.xin:7389'

? 以上的配置文件是确定gitlab监听的域名以及ip地址，当我们设置完成后执行以下命令将配置写入所有配置文件当中。

重新加载配置文件

gitlab-ctl reconfigure

3.启动Gitlab服务并检查服务是否正常启动。

启动Gitlab

gitlab-ctl start

ok: run: gitlab-workhorse: (pid 5294) 0s
ok: run: logrotate: (pid 5296) 0s
ok: run: nginx: (pid 5300) 0s
ok: run: postgresql: (pid 5302) 0s
ok: run: redis: (pid 5306) 0s
ok: run: sidekiq: (pid 5309) 0s
ok: run: unicorn: (pid 5312) 0s

检查Gitlab进程是否成功启动

ps aux|grep git

? 以上，我们已经将Gitlab服务启动完成，并监听在7389端口，下面我们开始配置前端nginx反向代理Gitlab。

二、配置Nginx反向搭理Gitlab

1.修改Nginx配置文件

vim /etc/nginx/conf.d/gitlab.conf

upstream  git{
    server  ip:port;
}


server{
    listen 80;
    server_name gitlab.federico.xin;

    location / {
        client_max_body_size 500m;
        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://git;
        index index.html index.htm;
    }
}

2.检查并重启Nginx

nginx -t

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

nginx -s reload

三、使用Gitlab过程中遇到的各种问题以及解决措施

1.fatal: The remote end hung up unexpectedly

? 在push代码到库时，出现上述报错，原因是因为上传的git包过大，可以通过以下设置解决此问题。
git config http.postBuffer 524288000

2.error: RPC failed; HTTP 413 curl 22 The requested URL returned error: 413 Request Entity Too Large

? 出现以上问题同样是因为上传软件包过大，需要我们在nginx参数中进行调整设置文件传输大小的限制。需要注意的是，如果是反向代理的Gitlab需要我们将两台服务器的nginx都进行设置。
grep -r "client_max_body_size" /var/opt/gitlab/

/var/opt/gitlab/nginx/conf/gitlab-http.conf:  client_max_body_size 500M;
/var/opt/gitlab/nginx/conf/nginx.conf:  client_max_body_size 50m;

vim /var/opt/gitlab/nginx/conf/nginx.conf

client_max_body_size 500m;

nginx -t
nginx -s reload
