其中2、配置防火墙可以直接改为关闭防火墙
查看防火墙状态：
[root@localhost ~]# systemctl status firewalld
● firewalld.service - firewalld - dynamic firewall daemon
Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
Active: active (running) since Thu 2020-05-28 16:54:59 CST; 2s ago
Docs: man:firewalld(1)
Main PID: 31821 (firewalld)
Tasks: 2
CGroup: /system.slice/firewalld.service

May 28 16:54:59 localhost.localdomain systemd[1]: Started firewalld - dynamic firewall daemon.
若为开启，则关闭防火墙：
[root@localhost ~]# systemctl stop firewalld
取消开机启动防火墙：
[root@localhost ~]# systemctl disable firewalld

修改gitlab端口
修改gitlab配置文件，并重新载入
[root@gitlab etc]#vim /opt/gitlab/etc/gitlab.rb
external_url '10.18.218.22:81' #修改为81端口
[root@gitlab etc]#gitlab-ctl reconfigure #执行此命令重新加载配置且同时启动gitlab所有服务
配置系统邮件
[root@gitlab etc]#vim /opt/gitlab/etc/gitlab.rb
gitlab_rails['smtp_enable'] = true
gitlab_rails['smtp_address'] = "mail.eee.com"
gitlab_rails['smtp_port'] = 465
gitlab_rails['smtp_user_name'] = "[email protected]"
gitlab_rails['smtp_password'] = "bbb"
#gitlab_rails['smtp_domain'] = "example.com"
gitlab_rails['smtp_authentication'] = "login"
gitlab_rails['smtp_enable_starttls_auto'] = true
gitlab_rails['smtp_tls'] = true
gitlab_rails['gitlab_email_from'] = '[email protected]'
[root@gitlab etc]#gitlab-ctl reconfigure #执行此命令重新加载配置且同时启动gitlab所有服务
