Linux 企业网站集群架构

一、企业环境架构介绍

二、Linux系统环境配置与优化

1. 部署流程：

   1.1）启动服务器

   1.2）配置CRT连接服务器

   1.3）查看硬件情况

   1.3.1）查看服务器产品名

   [[email protected]_server ~]# dmidecode | grep "Product Name"
           Product Name: VMware Virtual Platform
           Product Name: 440BX Desktop Reference Platform

   1.3.2）查看CPU情况

   [[email protected]_server ~]# grep name /proc/cpuinfo
   model name      : AMD A10-5800K APU with Radeon(tm) HD Graphics

   [[email protected]_server ~]# grep "physical id" /proc/cpuinfo
   1.3.3）查看内存信息

   [[email protected]_server ~]# grep Mem /proc/meminfo
   MemTotal:        1004412 kB
   MemFree:          426644 kB
   [[email protected]_server ~]# grep MemTotal /proc/meminfo
   MemTotal:        1004412 kB
   [[email protected]_server ~]#

   1.4）查看系统环境

   [[email protected]_server ~]# cat /etc/redhat-release
   CentOS release 6.5 (Final)
   [[email protected]_server ~]# uname -r
   2.6.32-431.el6.x86_64
   [[email protected]_server ~]# uname -m
   x86_64

   1.5）配置初始化系统

   1.5.1）配置防火墙和SELINUX

   [[email protected]_server ~]# chkconfig iptables off（关闭防火墙，如果联有外网需要启动防火墙）

   [[email protected]_server ~]# sed -i "s#SELINUX=enforcing#SELINUX=disabled#g" /etc/selinux/config

   [[email protected]_server ~]# setenforce 0

   1.5.2）添加一个系统用户
   [[email protected]_server ~]# useradd  oldboy

   [[email protected]_server ~]# echo "123456"|passwd --stdin oldboy

   1.5.3）配置yum源

   cd /etc/yum.repos.d/

   [[email protected]_server yum.repos.d]# wget http://mirrors.163.com/.help/CentOS6-Base-163.repo

   [[email protected]_server yum.repos.d]#yum clean all

   [[email protected]_server yum.repos.d]#yum makecache
