1.開始安裝依賴軟件：yum -y install policycoreutils openssh-server openssh-clients postfix
2.設置postfix開機自啓動,postfix支持gitlab發信功能：systemctl enable postfix && systemctl start postfix
如果出現：
Job for postfix.service failed because the control process exited with error code. See "systemctl status postfix.service" and "journalctl -xe" for details.
vim /etc/postfix/main.cf
inet_protocols = ipv4 inet_interfaces = all
3.下載gitlab包（建議去網站下載最新版本https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/?C=M&O=A）
wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-11.3.3-ce.0.el7.x86_64.rpm
rpm -i gitlab-ce-11.3.3-ce.0.el7.x86_64.rpm
如果報錯：
error: Failed dependencies:
policycoreutils-python is needed by gitlab-ce-10.7.3-ce.0.el7.x86_64
安裝環境
yum install policycoreutils-python
別的網站下載後有時候會報錯
4.修改gitlab 端口和ip
vim /etc/gitlab/gitlab.rb
IP地址+端口號： external_url 'http://192.168.0.217:8010'
5.配置並啓動gitlab
gitlab-ctl reconfigure (可能會一段時間)
gitlab-ctl restart
下圖表示成功
6.頁面打開 如果出現這個錯誤
1.更改端口號 vim /etc/gitlab/gitlab.rb（更改後要重新運行）
gitlab-ctl reconfigure (可能會一段時間)
gitlab-ctl restart
2.權限問題，解決方法：chmod -R 755 /var/log/gitlab
3.內存大於4G
7.首次進入會讓你修改密碼：修改後進入
.後來把端口改爲8081後就可以了
9.創建用戶
1.點擊小工具
2.添加user
10.關於發送郵箱。postfix默認用的25端口，但是阿里雲又不讓開啓25端口。
vim /etc/gitlab/gitlab.rb
gitlab_rails['smtp_enable'] = true gitlab_rails['smtp_address'] = "smtp.qq.com" gitlab_rails['smtp_port'] = 465 gitlab_rails['smtp_user_name'] = "[email protected]" # 你自己QQ號 gitlab_rails['smtp_password'] = "*************" # QQ授權碼 gitlab_rails['smtp_domain'] = "smtp.qq.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]' # 你自己QQ號
3.打開自己的qq郵箱
打開QQ郵箱-設置-賬戶-帳戶安全-開啓服務-POP3/SMTP服務-生成授權碼-發個短信
gitlab-ctl reconfigure 重新配置
4.進入gitlab-rails console
Notify.test_email('yoyo_你自己隨便郵箱@qq.com', '郵件標題_test', '郵件正文_test').deliver_now
[root@iZ2ze9m7ocdxc43mxwv5uwZ ~]# gitlab-rails console

5.現在創建用戶就會發送郵件
