执行
yum install policycoreutils-python再重新执行rpm的安装
显示安装成功
[root@iZm5e452n3se0jvpdlgbdpZ local]# whereis gitlab
gitlab: /etc/gitlab
[root@iZm5e452n3se0jvpdlgbdpZ local]# vim /etc/gitlab/gitlab.rb
设置external_url ‘http://ip地址’，保存
修改puma端口号puma['port'] = xxxx，默认为8080，不修改可能会有端口冲突导致gitlab报502
执行：
[root@bd ~]# gitlab-ctl reconfigure// 可能会打印许多信息
#最后提示成功信息语句

Chef Infra Client finished, 572/1516 resources updated in 04 minutes 33 seconds
Notes:
Default admin account has been configured with following details:
Username: root
Password: You didn't opt-in to print initial root password to STDOUT.
Password stored to /etc/gitlab/initial_root_password. This file will be cleaned up in first reconfigure run after 24 hours.
NOTE: Because these credentials might be present in your log files in plain text, it is highly recommended to reset the password following https://docs.gitlab.com/ee/security/reset_user_password.html#reset-your-root-password.
gitlab Reconfigured!如果reconfigure卡在ruby_block[wait for logrotate service socket]
执行systemctl restart gitlab-runsvdir
[root@bd ~]# gitlab-ctl restart
[root@bd ~]# gitlab-ctl status //查看状态

#启动成功输入刚才设置的ip和端口号，输入访问页面，正常
如果出现问题可使用tail命令查看日志定位问题，看看是否有端口占用的情况
gitlab-ctl tail如果gitlab报错502，不仅要看external_url的端口，同时要看puma和unicorn的端口占用情况
3.修改root密码
’root初始密码在下面这个文件中，24小时候会自动删除，root账号登陆后需要尽快修改密码
/etc/gitlab/initial_root_password4.常用操作命令
#配置重新加载
gitlab-ctl reconfigure
# 启动gitlab
gitlab-ctl start
# 停止gitlab
gitlab-ctl stop
# 查看gitlab命令
gitlab-ctl --help
#查看gitlab日志
gitlab-ctl tail [process name] #[process name可选]5.卸载gitlab
#先杀死进程
kill -9 xxx
#卸载gitlab（ce是社区版）
rpm -e gitlab-ce
#最后删除文件
find / -name gitlab | xargs rm -rf6.docker安装gitlab
# 拉取社区版镜像
docker pull gitlab/gitlab-ce 新建宿主机映射文件夹
mkdir -p /home/docker/gitlab/etc
mkdir -p /home/docker/gitlab/logs
mkdir -p /home/docker/gitlab/data
启动gitlab的docker镜像
docker run
-d #后台运行，全称：detach
-p 8443:443 #将容器内部端口向外映射
-p 8061:80 #将容器内80端口映射至宿主机8090端口，这是访问gitlab的端口
-p 8022:22 #将容器内22端口映射至宿主机8022端口，这是访问ssh的端口
--restart always #容器自启动
--name my-gitlab #设置容器名称为my-gitlab
-v /home/docker/gitlab/etc:/etc/gitlab #将容器/etc/gitlab目录挂载到宿主机/home/docker/gitlab/etc目录下，若宿主机内此目录不存在将会自动创建
-v /home/docker/gitlab/log:/var/log/gitlab #与上面一样
-v /home/docker/gitlab/data:/var/opt/gitlab #与上面一样
--privileged=true #让容器获取宿主机root权限
gitlab/gitlab-ce #镜像的名称，这里也可以写镜像ID
修改配置文件
vim /home/docker/gitlab/etc/gitlab.rb需修改的内容同linux直接安装一样，调整为docker映射过后的宿主机的对应配置（需注意docker容器需要映射宿主机端口，这里external_url ‘http://ip地址’，不需要额外填写端口号）
然后进入容器
docker exec -it my-gitlab bash修改配置文件
cd /opt/gitlab/embedded/service/gitlab-rails/config
//打开编辑gitlab.yml文件
vim gitlab.yml修改此处为之前对应配置的ip+port
# 重启gitlab
gitlab-ctl restart
# 退出容器
exit
使用docker安装gitlab安装完毕！
