搭建环境：

操作系统：CentOS 6.7

Nginx软件：Nginx-1.8.1.tar.gz

MysqL软件：MysqL-5.5.51-linux2.6-x86_64.tar.gz

PHP软件：PHP-5.6.11.tar.gz

一、LNMP安装前环境准备

1、设置linux防火墙

1）在iptables上开放80,3306,443端口

[root@db ~]# vim /etc/sysconfig/iptables

# Firewall configuration written by system-config-firewall

# Manual customization of this file is not recommended.

*filter

:INPUT ACCEPT [0:0]

:FORWARD ACCEPT [0:0]

:OUTPUT ACCEPT [0:0]

-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT

-A INPUT -p icmp -j ACCEPT

-A INPUT -i lo -j ACCEPT

-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT

-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT

-A INPUT -m state --state NEW -m tcp -p tcp --dport 443 -j ACCEPT

-A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT

-A INPUT -j REJECT --reject-with icmp-host-prohibited

-A FORWARD -j REJECT --reject-with icmp-host-prohibited

COMMIT

[root@db ~]# service iptables restart-----重启iptables服务

2）关闭selinux防火墙

[root@db ~]# vim /etc/sysconfig/selinux

# This file controls the state of SELinux on the system.

# SELINUX= can take one of these three values:

# enforcing - SELinux security policy is enforced.

# permissive - SELinux prints warnings instead of enforcing.

# disabled - No SELinux policy is loaded.

SELINUX=disabled

# SELINUXTYPE= can take one of these two values:

# targeted - Targeted processes are protected,

# mls - Multi Level Security protection.

SELINUXTYPE=targeted

[root@db ~]#setenforc 0

3)安装依赖包

[root@db ~]#yum-yinstallgccgcc-c++autoconflibjpeglibjpeg-devellibpnglibpng-develfreetypefreetype-devellibxml2libxml2-develzlibzlib-develglibcglibc-develglib2glib2-develbzip2bzip2-develncursesncurses-develcurlcurl-devele2fsprogse2fsprogs-develkrb5krb5-devellibidnlibidn-developensslopenssl-developenldapopenldap-developenldap-clientsopenldap-serversmakelibtool*gittreebisonpcre-develperlgdgd-devel

4）编译安装其他软件


A：安装libiconv软件（该软件支持编码转换为函数）

[root@db software]# tar xf libiconv-1.14.tar.gz

[root@db libiconv-1.14]#./configure--prefix=/usr/local

[root@db libiconv-1.14]#make&&makeinstall

[root@db libiconv-1.14]# echo $?

0

（显示0，表示软件编译安装成功了）

B：安装libmcrypt （加密算法扩展库，支持DES,3DES,RIJNDAEL,Twofish,IDEA,GOST,CAST-256,ARCFOUR,SERPENT,SAFER+等算法)

[root@db software]# tar xf libmcrypt-2.5.7.tar.gz

[root@db software]# cd libmcrypt-2.5.7

[root@db libmcrypt-2.5.7]# ./configure

[root@db libmcrypt-2.5.7]# cd libltdl/

[root@db libltdl]# ./configure --enable-ltdl-install

[root@db libltdl]# make && make install

C: 安装mhash（mhash的可以用于创建校验数值，消息摘要，消息认证码，以及无需原文的关键信息保存）

[root@db software]# tar xf mhash-0.9.9.9.tar.gz

[root@db software]# cd mhash-0.9.9.9

[root@db mhash-0.9.9.9]# ./configure && make && make install

D：安装mcript（mcrypt 是 PHP 里面重要的加密支持扩展库，Mcrypt扩展库可以实现加密解密功能，就是既能将明文加密，也可以密文还原。）

[root@db software]# tar xf mcrypt-2.6.8.tar.gz

[root@db software]# cd mcrypt-2.6.8

[root@db mcrypt-2.6.8]# export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH

[root@db mcrypt-2.6.8]# ./configure && make && make install

E：增加库文件
