(2) Virtual machine network configuration process: https://blog.csdn.net/llwy1428/article/details/85058028

2. Install basic tools

[root@controller ~]# yum install -y curl policycoreutils-python openssh-server openssh-clirnts postfixcronie lokkit rpm

3. Close SELINUX permanently (restart to take effect)

Temporarily close SELINUX

[root@controller ~]# setenforce 0

4. Turn off the firewall (or open the designated port)

关闭防火墙    ： systemctl stop firewalld
查看状态      ： systemctl status firewalld
开机禁用      ： systemctl disable firewalld

Please refer to other firewall operations

5. Use the lokkit command to set up the firewall and open HTTP and SSH access permissions

[root@controller ~]# systemctl enable sshd

[root@controller ~]# systemctl start sshd

[root@controller ~]# systemctl enable postfix

[root@controller ~]# systemctl start postfix

[root@controller ~]# lokkit -s http -s ssh

6. Create a directory and download the installation package

[root@controller ~]# mkdir /opt/gitlab

[root@controller ~]# cd /opt/gitlab

Download the gitlab-ce-12.6.1-ce.0.el7.x86_64.rpm installation package (can be downloaded manually)

Download link: https://packages.gitlab.com/gitlab/gitlab-ce/

After downloading, put the file gitlab-ce-12.6.1-ce.0.el7.x86_64.rpm under the /opt/gitlab/ directory, and perform step 7.

(You can also execute the installation command on the official website)

reference:

[root@controller gitlab]# curl -s https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.rpm.sh | sudo bash

7. Perform installation gitlab-ce

[root@controller gitlab]# yum install gitlab-ce-12.6.1-ce.0.el7.x86_64.rpm -y

If the installation fails, as follows:

Manual download

[root@localhost gitlab]# wget --content-disposition https://packages.gitlab.com/gitlab/gitlab-ce/packages/el/7/gitlab-ce-12.9.10-ce.0.el7.x86_64.rpm/download.rpm

8. Modify the configuration file gitlab-ce

[root@controller ~]# vim /etc/gitlab/gitlab.rb

unicorn['port'] is recommended to be modified, otherwise a "502" error will be reported when the service is restarted, causing the system to fail to log in.

(The port does not conflict with the existing service port of the system)
