CentOS7 安装Gitlab

1、安装依赖

sudo yum install -y curl openssh-server ca-certificates tzdata perl libsemanage-devel

2、安装邮件服务工具

sudo yum install -y postfix

3、配置GitLab 软件源镜像

curl -fsSL https://packages.gitlab.cn/repository/raw/scripts/setup.sh | /bin/bash

4、安装Gitlab

sudo yum install gitlab-jh

5、制作私钥、公钥证书（开启https访问才需要）

openssl version

生成私钥：openssl genrsa -des3 -out server.key 3072

通过key文件生成.csr文件：openssl req -new -key server.key -out server.csr

免除.key文件的密码：openssl rsa -in server.key -out server.key

通过.key和.csr文件生成.crt文件：openssl x509 -req -days 3650 -in server.csr -signkey server.key -out server.crt

修改gitlab.rb文件：vim /etc/gitlab/gitlab.rb

需要修改配置有：

external_url "https://IP"

nginx['redirect_http_to_https']= true

nginx['ssl_certificate']= "/etc/gitlab/ssl/server.crt"

nginx['ssl_certificate_key']= "/etc/gitlab/ssl/server.key"

nginx['enable'] = true

nginx['redirect_http_to_https_port'] = 80

6、配置Gitlab实例

sudo gitlab-ctl reconfigure

7、启动Gitlab、查看状态
sudo gitlab-ctl start

sudo gitlab-ctl status

8、关闭防火墙

systemctl disable firewall.service

systemctl stop firewall.service

9、开启服务自启动

systemctl enable gitlab-runsvdir.service

10、本地git客户端工具关闭ssl安全校验，自己制作的证书没通过校验。

git config --global http.sslVerify false

11、使用IP登录Gitlab

root密码通过一下方式获取：

# cat /etc/gitlab/initial_root_password
Password: ARVVjpDcF5g/ZG2DScarmU9s9TKUT09HQd3qUj4jq/c=

或者重置密码：

# cd /opt/gitlab/bin
# gitlab-rails console
