Linux环境之gitlab搭建

==----------------------------------------------------------------------------------------------------------------------

-----== LINUX gitlab搭建配置  参考：https://blog.youkuaiyun.com/duyusean/article/details/80011540  【成功！！！！】

注：centos环境需三个依赖：ssh、防火墙、postfix

1、安装依赖-ssh
    sudo yum install -y curl policycoreutils-pythonopenssh-server

    [root@iZm5eizpokikoertia0x31Z /]# sudo yum install -y curl policycoreutils-pythonopenssh-server
    Loaded plugins: fastestmirror
    Loading mirror speeds from cached hostfile
    base                                                                                              | 3.6 kB  00:00:00
    epel                                                                                              | 5.3 kB  00:00:00
    extras                                                                                            | 3.4 kB  00:00:00
    updates                                                                                           | 3.4 kB  00:00:00
    Package curl-7.29.0-51.el7.x86_64 already installed and latest version
    No package policycoreutils-pythonopenssh-server available.


2、将ssh服务设置为开机启动
    sudo systemctl enable sshd

3、启动ssh服务
    sudo systemctl start sshd

4、安装防火墙
    yum install firewalld systemd -y

    [root@iZm5eizpokikoertia0x31Z /]# yum install firewalld systemd -y
    Loaded plugins: fastestmirror
    Loading mirror speeds from cached hostfile
    Package firewalld-0.5.3-5.el7.noarch already installed and latest version
    Package systemd-219-62.el7_6.6.x86_64 already installed and latest version
    Nothing to do

5、开启防火墙
    service firewalld  start
    [root@iZm5eizpokikoertia0x31Z /]# service firewalld  start
    Redirecting to /bin/systemctl start firewalld.service

    [root@iZm5eizpokikoertia0x31Z /]# /bin/systemctl start firewalld.service
    [root@iZm5eizpokikoertia0x31Z /]#


6、添加http服务到firewalld,permanent表示永久生效，若不加--permanent，系统下次启动就会失效
    sudo firewall-cmd --permanent --add-service=http

    [root@iZm5eizpokikoertia0x31Z /]# sudo firewall-cmd --permanent --add-service=http
    success

7、重启防火墙
    /bin/systemctl restart firewalld.service

8、安装postfix邮件通知系统

    查看是否安装：rpm -q postfix

    sudo yum install postfix

    [root@iZm5eizpokikoertia0x31Z /]# sudo yum install postfix
    Loaded plugins: fastestmirror
    Loading mirror speeds from cached hostfile
    Package 2:postfix-2.10.1-7.el7.x86_64 already installed and latest version
    Nothing to do

9、将postfix服务设置为开机启动
    sudo systemctl enable postfix

10、启动postfix
    sudo systemctl start postfix

    [root@iZm5eizpokikoertia0x31Z system]# sudo systemctl start postfix
    Job for postfix.service failed because the control process exited with error code. See "systemctl status postfix.service" and "journalctl -xe" for details.


    查看postfix: rpm -qa | grep postfix


    [root@iZm5eizpokikoertia0x31Z lib]# systemctl status postfix.service
    ● postfix.service - Postfix Mail Transport Agent
       Loaded: loaded (/usr/lib/systemd/system/postfix.service; enabled; vendor preset: disabled)

    Jun 18 17:52:36 iZm5eizpokikoertia0x31Z systemd[1]: postfix.service failed.

    经过了一些列的处理：
    sudo systemctl enable postfix
    [root@iZm5eizpokikoertia0x31Z system]# sudo systemctl start postfix
    Job for postfix.service failed because the control process exited with error code. See "systemctl status postfix.service" and "journalctl -xe" for details.

    -------------------------------------------

    没成功，继续：
    vi /etc/postfix/main.cf
    修改 /etc/postfix/main.cf的设置
    inet_protocols = ipv4
    inet_interfaces = all
    重新启动postfix即可
    systemctl start postfix.service
