Ubuntu 系统环境安装前准备

配置ubuntu 远程连接

[wang@ubuntu1804 ~]$ sudo su - root
[sudo] password for wang:
root@ubuntu:~# passwd 
Enter new UNIX password: 
Retype new UNIX password: 
passwd: password updated successfully
[root@ubuntu1804 ~]# vim /etc/ssh/sshd_config
PermitRootLogin yes

配置ubuntu网卡和主机名

[root@ubuntu1804 ~]#cat /etc/netplan/01-netcfg.yaml
# This file describes the network interfaces available on your system
# For more information, see netplan(5).
network:
  version: 2
  renderer: networkd
  ethernets:
    eth0:
      addresses:
      - 10.0.0.100/24
      gateway4: 10.0.0.2
      nameservers:
        search: [magedu.com, magedu.org]
        addresses: [180.76.76.76, 223.6.6.6]

配置ubuntu 仓库

配置阿里云仓库实现加速

[root@ubuntu1804 ~]#vim /etc/apt/sources.list

安装常见软件

[root@ubuntu1804 ~]# apt update
[root@ubuntu1804 ~]# apt install iproute2 ntpdate tcpdump telnet traceroute nfs-kernel-server nfs-common lrzsz tree openssl libssl-dev libpcre3 libpcre3-dev zlib1g-dev ntpdate tcpdump telnet traceroute gcc openssh-server lrzsz tree openssl libssl-dev libpcre3 libpcre3-dev zlib1g-dev ntpdate tcpdump telnet traceroute iotop unzip zip ipmitool

Centos 系统环境安装前准备

基于最小化服务器安装，准备配置如下：

# yum install vim gcc gcc-c++ wget net-tools lrzsz iotop lsof iotop bash-completion -y
# yum install curl policycoreutils openssh-server openssh-clients postfix -y
# wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
# systemctl disable firewalld
# sed -i '/SELINUX/s/enforcing/disabled/' /etc/sysconfig/selinux
# hostnamectl set-hostname gitlab.example.com
# reboot

初始化服务

执行配置并启动服务：

#修改完配置文件要执行此操作
[root@ubuntu1804 ~]# gitlab-ctl  reconfigure 

验证gitlab启动完成

常用命令

gitlab-rails #用于启动控制台进行特殊操作，如修改管理员密码、打开数据库控制台( gitlab-rails dbconsole)等
gitlab-psql #数据库命令行
gitlab-rake #数据备份恢复等数据操作

gitlab-ctl  #客户端命令行操作行
gitlab-ctl stop #停止gitlab
gitlab-ctl start #启动gitlab
gitlab-ctl restar #重启gitlab
gitlab-ctl  status #查看组件运行状态
gitlab-ctl  tail nginx #查看某个组件的日志

范例：

[root@ubuntu1804 ~]#gitlab-psql
psql (9.6.11)
Type "help" for help.

gitlabhq_production=# help
You are using psql, the command-line interface to PostgreSQL.
Type:  /copyright for distribution terms
       /h for help with SQL commands
       /? for help with psql commands
       /g or terminate with semicolon to execute query
       /q to quit
gitlabhq_production=# /db
         List of tablespaces
    Name    |    Owner    | Location
------------+-------------+----------
 pg_default | gitlab-psql |
 pg_global  | gitlab-psql |
(2 rows)

gitlabhq_production-# /q
[root@ubuntu1804 ~]#

验证端口及状态

80端口是在初始化gitlib的时候启动的，因此如果之前的有程序占用会导致初始化失败或无法访问

[root@ubuntu1804 ~]#lsof -i :80
COMMAND   PID       USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
nginx   28851       root    7u  IPv4  88801      0t0  TCP *:http (LISTEN)
nginx   28852 gitlab-www    7u  IPv4  88801      0t0  TCP *:http (LISTEN)
nginx   28853 gitlab-www    7u  IPv4  88801      0t0  TCP *:http (LISTEN)
