centos 安装gitlab
1.开始安装依赖软件：yum -y install policycoreutils openssh-server openssh-clients postfix
2.设置postfix开机自启动,postfix支持gitlab发信功能：systemctl enable postfix && systemctl start postfix
如果出现：
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.下载gitlab包（建议去网站下载最新版本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
如果报错：
error: Failed dependencies:
policycoreutils-python is needed by gitlab-ce-10.7.3-ce.0.el7.x86_64
安装环境
yum install policycoreutils-python
别的网站下载后有时候会报错
4.修改gitlab 端口和ip
vim /etc/gitlab/gitlab.rb
IP地址+端口号： external_url 'http://192.168.0.217:8010'
5.配置并启动gitlab
gitlab-ctl reconfigure (可能会一段时间)
gitlab-ctl restart
下图表示成功
6.页面打开 如果出现这个错误
1.更改端口号 vim /etc/gitlab/gitlab.rb（更改后要重新运行）
gitlab-ctl reconfigure (可能会一段时间)
gitlab-ctl restart
2.权限问题，解决方法：chmod -R 755 /var/log/gitlab
3.内存大于4G
7.首次进入会让你修改密码：修改后进入
.后来把端口改为8081后就可以了
9.创建用户
1.点击小工具
2.添加user
10.关于发送邮箱。postfix默认用的25端口，但是阿里云又不让开启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'] = "2833xxx@qq.com" # 你自己QQ号 gitlab_rails['smtp_password'] = "*************" # QQ授权码 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'] = '2833xxx@qq.com' # 你自己QQ号
3.打开自己的qq邮箱
打开QQ邮箱-设置-账户-帐户安全-开启服务-POP3/SMTP服务-生成授权码-发个短信
gitlab-ctl reconfigure 重新配置
4.进入gitlab-rails console
Notify.test_email('yoyo_你自己随便邮箱@qq.com', '邮件标题_test', '邮件正文_test').deliver_now
[root@iZ2ze9m7ocdxc43mxwv5uwZ ~]# gitlab-rails console
