GitLab导致8080端口冲突

问题复现

安装完GitLab后,修改配置文件/etc/gitlab/gitlab.rb

##external_url 'http://gitlab.example.com'
external_url 'http://localhost:8800'

本以为这样就能修改GitLab端口号为8800了,没想到再次登录8080仍旧出现了GitLab页面

问题解析

查询哪个程序监听了8080端口

# netstat -lnp | grep 8080
tcp        0      0 127.0.0.1:8080          0.0.0.0:*               LISTEN      26436/config.ru 

查询相应的进程

# netstat -lnp | grep 26436
tcp        0      0 127.0.0.1:8080          0.0.0.0:*               LISTEN      26436/config.ru 
unix  2      [ ACC ]     STREAM     LISTENING     343538   26436/config.ru     /var/opt/gitlab/gitlab-rails/sockets/gitlab.socket

仍然是GitLab在监听8080端口,参考gitlab 8.13 80 8080端口冲突问题,查看配置文件unicorn.rb

# This file is managed by gitlab-ctl. Manual changes will be
# erased! To change the contents below, edit /etc/gitlab/gitlab.rb
# and run `sudo gitlab-ctl reconfigure`.

# What ports/sockets to listen on, and what options for them.
listen "127.0.0.1:8080", :tcp_nopush => true

默认情况下unicorn同样监听8080端口,查询/etc/gitlab/gitlab.rb中相应的设置

# cat gitlab.rb | grep unicorn
#unicorn['port'] = 8800

解决方案

需要在gitlab.rb上同时修改unicorn监听端口号,修改配置文件/etc/gitlab/gitlab.rb如下

##external_url 'http://gitlab.example.com'
external_url 'http://localhost:8800'
unicorn['port'] = 8801

重新启动GitLab

# gitlab-ctl reconfigure
# gitlab-ctl restart

查询配置文件/var/opt/gitlab/gitlab-rails/etc/unicorn.rb

# cat unicorn.rb | grep listen
# What ports/sockets to listen on, and what options for them.
listen "127.0.0.1:8801", :tcp_nopush => true

测试端口号

$ curl localhost:8080
curl: (7) Failed to connect to localhost port 8080: Connection refused
