<b>CentOS 5.6 快速搭建LAMP</b>[服务器安全]

在虚拟机下安装了个CentOS,5.6版本的.操纵NAT情势与宿主pc同享上网!   
当然可以采取编译源码的方法搭建lamp.这里只是介绍快速搭建php开辟框架的办法.其实也没什么,主如果是是利用linux的yum来在线安装.假如上不了网请查找编译源码搭建lamp的文章.网上N多的哈^_^
   1.安装mysql数据库

     号令行下:yum -y install mysql mysql-server   

     Setting up Install Process
     Setting up repositories... ....

     ....................................................

     Installed: mysql-server.i386 0:4.1.20-1.RHEL4.1
     Dependency Installed: mysql.i386 0:4.1.20-1.RHEL4.1 perl-DBD-MySQL.i386 0:2.9004-3.1 perl-DBI.i386 0:1.40-8
     Complete!

    安装完毕,配置mysql:

   号令行下:vi /etc/my.cnf        提醒:红色字为增添的行,主如果设置数据库默许的字符集为utf8

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
# Default to using old password format for compatibility with mysql 3.x
# clients (those using the mysqlclient10 compatibility package).
old_passwords=1
default-character-set = utf8
# Disabling symbolic-links is recommended to prevent assorted security risks;
# to do so, uncomment this line:
# symbolic-links=0

[mysql]

default-character-set = utf8

 保存退出后,设置mysql服务随系统自启动,

号令行下:chkconfig mysqld on

       可以通过chkconfig --list mysqld 查看设置状况,显示 mysqld 0:off 1:off 2:on 3:on 4:on 5:on 6:off,2~5显示On便可以了.
 

  启动mysql服务, /etc/rc.d.init.d/mysqld start

      Initializing MySQL database:　　　　　　　　 [ OK ]
      Starting MySQL: 　　　　　　　　　　　　　[ OK ]

可以登录mysql举行测试:mysql -u -root                     *(默许root的密码是空的)

呈现提醒符“mysql〉”后,设置root的密码.

以下行动出于安全考虑:

号令行下:mysql> use  mysql;

                    mysql> set password for root@localhost = password('你的密码');

                    mysql> set password for root@localhost.localdomain=password('你的密码');

删除匿名用户: mysql> delete from user where user='';    

删除测试数据库: mysql> drop database test;

至此,mysql数据安装完成,可以用sql操作mysql测试.

2.安装apache

号令行下:yum -y install apache

Setting up Install Process
Setting up repositories

....................................

Complete!

接下来配置apache,编辑Apache的配置文件,号令行下:vi /etc/httpd/conf/httpd.conf

#
# Don't give away too much information about all the subcomponents
# we are running. Comment out this line if you don't mind remote sites
# finding out what major optional modules you are running
ServerTokens OS　 ← 找到这一行,将“OS”改成“Prod”（在呈现错误页的时刻不显示服务器操作系统的名称）
↓
ServerTokens Prod 　 ← 变成此状况

#
# Optionally add a line containing the server version and virtual host
# name to server-generated pages (internal error documents, FTP directory
# listings, mod_status and mod_info output etc., but not CGI generated
# documents or custom error documents).
# Set to "EMail" to also include a mailto: link to the ServerAdmin.
# Set to one of: On | Off | EMail
#
ServerSignature On　 ← 找到这一行,将“On”改成“Off”
↓
ServerSignature Off　 ← 在错误页中不显示Apache的版本

#
# ServerName gives the name and port that the server uses to identify itself.
# This can often be determined automatically, but we recommend you specify
# it explicitly to prevent problems during startup.
#
# If this is not set to valid DNS name for your host, server-generated
# redirections will not work. See also the UseCanonicalName directive.
#
# If your host doesn't have a registered DNS name, enter its IP address here.
# You will have to access it by its address anyway, and this will make
# redirections work in a sensible way.
#
#ServerName new.host.name:80　 ← 改正主机名
↓
ServerNam
