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

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 successfulnginx -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
