centos安装gitlab

1.打开系统防火墙 HTTP 和 SSH 的访问,安装postfix

sudo yum install curl policycoreutils policycoreutils-python openssh-server openssh-clients
sudo systemctl enable sshd
sudo systemctl start sshd
sudo yum install postfix
sudo systemctl enable postfix
sudo systemctl start postfix
sudo firewall-cmd --permanent --add-service=http
sudo systemctl reload firewalld

2.下载gitlab rpm安装文件

crul下载：

> curl -s https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.rpm.sh | sudo bash
> sudo yum install gitlab-ce-10.1.0-ce.0.el7.x86_64

rpm下载

curl -LJO https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-10.1.0-ce.0.el7.x86_64.rpm
rpm -i gitlab-ce-10.1.0-ce.0.el7.x86_64.rpm

如果下载失败，可以到https://packages.gitlab.com/gitlab/gitlab-ce手动下载，再用 rpm的方式自己安装

出现 It looks like… 表示安装成功！

3.配置 gitlab 

vi /etc/gitlab/gitlab.rb

把external_url改成部署机器的域名或者IP地址。

4.对GitLab进行重配置 （这一步也是启动 GitLab）

gitlab-ctl reconfigure

遇到的坑：

ruby_block[supervise_redis_sleep] action run，会一直卡无法往下进行

解决方案：

1、按住CTRL+C强制结束；

2、运行：sudo systemctl restart gitlab-runsvdir；

3、再次执行：sudo gitlab-ctl reconfigure

找不到文件 /var/opt/gitlab/postgresql/.s.PGSQL.5432

怀疑可能是执行的时候没有权限创建

sudo chmod 755 postgresql/
