CentOS 6系统手动安装LAMP环境（通用版）

一、安装/配置Apache

1.更新系统&安装Apache

yum update
yum install httpd

推荐：使用如下命令备份Apache配置文件

cp /etc/httpd/conf/httpd.conf ~/httpd.conf.backup

为了给大家拓展思路，本次在CentOS上的教程，和大家分享Apache的另外一种绑定域名和创建虚拟机的方式~

2.编辑/etc/httpd/conf.d/vhost.conf，假设我们要绑定example.com和example.org两个域名，则参照下面内容加入文件，

NameVirtualHost *:80

     ServerAdmin webmaster@example.com
     ServerName example.com
     ServerAlias www.111com.net
     DocumentRoot /srv/www/example.com/public_html/
     ErrorLog /srv/www/example.com/logs/error.log
     CustomLog /srv/www/example.com/logs/access.log combined

     ServerAdmin webmaster@example.org
     ServerName example.org
     ServerAlias www.example.org
     DocumentRoot /srv/www/example.org/public_html/
     ErrorLog /srv/www/example.org/logs/error.log
     CustomLog /srv/www/example.org/logs/access.log combined

3.因为我们上文指定了几个目录而这几个目录还不存在，所以，使用如下命令创建相应目录，

mkdir -p /srv/www/example.com/public_html
mkdir /srv/www/example.com/logs

mkdir -p /srv/www/example.org/public_html
mkdir /srv/www/example.org/logs

4.启动Apache

/etc/init.d/httpd start

日后每次修改vhost.conf文件，都需要使用如下命令使Apache重新载入配置文件

/etc/init.d/httpd reload

5.设置Apache开机启动

/sbin/chkconfig --levels 235 httpd on

二、安装/配置MySQL

1.安装MySQL

yum install mysql-server

2.设置MySQL开机自动启动

/sbin/chkconfig --levels 235 mysqld on

3.启动MySQL

/etc/init.d/mysqld start

MySQL的配置文件位于/etc/my.cnf

4.安装mysql_secure_installation（MySQL安全设置）

mysql_secure_installation

5.附上常用的MySQL命令

登录MySQL

mysql -u root -p

创建数据库vmvps（注意MySQL命令行下都需要以;结尾），并将该数据库所有权限赋予vmvps_user(密码为123)

create database vmvps;
grant all on vmvps.* to 'vmvps_user' identified by '123';

退出MySQL

quit

三、安装/配置PHP

1.安装PHP

yum install php php-pear php-mysql

2.编辑配置文件/etc/php.ini，修改如下内容

error_reporting = E_COMPILE_ERROR|E_RECOVERABLE_ERROR|E_ERROR|E_CORE_ERROR
display_errors = Off
log_errors = On
error_log = /var/log/php.log
max_execution_time = 300
memory_limit = 64M
register_globals = Off

最后，重启Apache，大功告成~

/etc/init.d/httpd restart

四、CentOS配置VSFTP服务器

[1] 安装VSFTP

[root@localhost ~]# yum -y install vsftpd

[2] 配置vsftpd.conf文件

[root@localhost ~]# vi /etc/vsftpd/vsftpd.conf

# Example config file /etc/vsftpd/vsftpd.conf
#
# The default compiled in settings are fairly paranoid. This sample file
# loosens things up a bit, to make the ftp daemon more usable.
# Please see vsftpd.conf.5 for all compiled in defaults.
#
# READ THIS: This example file is NOT an exhaustive list of vsftpd options.
# Please read the vsftpd.conf.5 manual page to get a full idea of vsftpd's
# capabilities.
#
# Allow anonymous FTP? (Beware - allowed by default if you comment this out).
#anonymous_enable=YES
#
# Uncomment this to allow local users to log in.
local_enable=YES
#
# Uncomment this to enable any form of FTP write command.
write_enable=YES
#
# Default umask for local users is 077. You may wish to change this to 022,
# if your users expect that (022 is used by most other ftpd's)
local_umask=022
#
# Uncomment this to allow the anonymous FTP user to upload files. This only
# has an effect if the above global write enable is activated. Also, you will
# obviously need to create a directory writable by the FTP user.
#anon_upload_enable=YES
#
# Uncomment this if you want the anonymous FTP user to be able to create
# new directories.
#anon_mkdir_write_enable=YES
#
# Activate directory messages - messages given to remote users when they
# go into a certain directory.
dirmessage_enable=YES
#
# The target log file can be vsftpd_log_file or xferlog_file.
# This depends on setting xferlog_std_format parameter
xferlog_enable=YES
#
# Make sure PORT transfer connections originate from port 20 (ftp-data).
connect_from_port_20=YES
#
# If you want, you can arrange for uploaded anonymous files to be owned by
# a different user. Note! Using "root" for uploaded files is not
# recommended!
#chown_uploads=YES

#chown_username=whoever
#
# The name of log file when xferlog_enable=YES and xferlog_std_format=YES
# WARNING - changing this filename affects /etc/logrotate.d/vsftpd.log
#xferlog_file=/var/log/xferlog
#
# Switches between logging into vsftpd_log_file and xferlog_file files.
# NO writes to vsftpd_log_file, YES to xferlog_file
xferlog_std_format=YES
#
# You may change the default value for timing out an idle session.
idle_session_timeout=600
#
# You may change the default value for timing out a data connection.
data_connection_timeout=120
#
# It is recommended that you define on your system a unique user which the
# ftp server can use as a totally isolated and unprivileged user.
#nopriv_user=ftpsecure
#
# Enable this and the server will recognise asynchronous ABOR requests. Not
# recommended for security (the code is non-trivial). Not enabling it,
# however, may confuse older FTP clients.
#async_abor_enable=YES
#
# By default the server will pretend to allow ASCII mode but in fact ignore
# the request. Turn on the below options to have the server actually do ASCII
# mangling on files when in ASCII mode.
# Beware that on some FTP servers, ASCII support allows a denial of service
# attack (DoS) via the command "SIZE /big/file" in ASCII mode. vsftpd
# predicted this attack and has always been safe, reporting the size of the
# raw file.
# ASCII mangling is a horrible feature of the protocol.
ascii_upload_enable=YES
ascii_download_enable=YES

#
# You may fully customise the login banner string:
ftpd_banner=Welcome to lightnear FTP service.
#
# You may specify a file of disallowed anonymous e-mail addresses. Apparently
# useful for combatting certain DoS attacks.
#deny_email_enable=YES
# (default follows)
#banned_email_file=/etc/vsftpd/banned_emails
#
# You may specify an explicit list of local users to chroot() to their home
# directory. If chroot_local_user is YES, then this list becomes a list of
# users to NOT chroot().
chroot_local_user=YES
#chroot_list_enable=YES
# (default follows)
#chroot_list_file=/etc/vsftpd/chroot_list
#
# You may activate the "-R" option to the builtin ls. This is disabled by
# default to avoid remote users being able to cause excessive I/O on large
# sites. However, some broken FTP clients such as "ncftp" and "mirror" assume
# the presence of the "-R" option, so there is a strong case for enabling it.
ls_recurse_enable=YES
#
# When "listen" directive is enabled, vsftpd runs in standalone mode and
# listens on IPv4 sockets. This directive cannot be used in conjunction
# with the listen_ipv6 directive.
listen=YES
#
# This directive enables listening on IPv6 sockets. To listen on IPv4 and IPv6
# sockets, you must run two copies of vsftpd with two configuration files.
# Make sure, that one of the listen options is commented !!
#listen_ipv6=YES

pam_service_name=vsftpd
userlist_enable=YES
userlist_deny=NO
local_root=/var/public_root
tcp_wrappers=YES

use_localtime=YES

[3] 增加FTP帐户

[root@localhost ~]# useradd cent -s /sbin/nologin
[root@localhost ~]# passwd cent

[4] 编辑user_list文件，允许cent用户访问FTP

[root@localhost ~]# vi /etc/vsftpd/user_list
# vsftpd userlist
# If userlist_deny=NO, only allow users in this file
# If userlist_deny=YES (default), never allow users in this file, and
# do not even prompt for a password.
# Note that the default vsftpd pam config also checks /etc/vsftpd/ftpusers
# for users that are denied.
root
bin
daemon
adm
lp
sync
shutdown
halt
mail
news
uucp
operator
games
nobody
cent

[5] 建立我们的根目录，并设置访问权限

[root@localhost ~]# mkdir /var/public_root
[root@localhost ~]# chown -R cent /var/public_root
[root@localhost ~]# chmod -R 755 /var/public_root
[6] 开启vsftpd服务

[root@localhost ~]# service vsftpd start
Starting vsftpd for vsftpd:                                [  OK  ]
[7] 默认开启vsftp服务

[root@localhost var]# chkconfig vsftpd on

五、防火强配置

iptables 常用配置

iptables有多个参数，iptable因为是按照顺序来执行的，有匹配的就不进行下一步了。
-I表示插入一条，这个用的较多
-A表示追加到最后
-D表示删除一条

-A RH-Firewall-1-INPUT -p icmp -m icmp --icmp-type any -j ACCEPT
接收ping包

禁止所有数据包，一般用在最后
-A RH-Firewall-1-INPUT -j REJECT --reject-with icmp-host-prohibited

常用的IPTABLES规则如下：

只能收发邮件，别的都关闭
iptables -I Filter -m mac –mac-source 00:0F:EA:25:51:37 -j DROP
iptables -I Filter -m mac –mac-source 00:0F:EA:25:51:37 -p udp –dport 53 -j ACCEPT
