搭建環境：
操作系統：CentOS 6.7
nginx軟件：nginx-1.8.1.tar.gz
mysql軟件：mysql-5.5.51-linux2.6-x86_64.tar.gz
PHP軟件：php-5.6.11.tar.gz
一、LNMP安裝前環境準備
1、設置linux防火牆
1）在iptables上開放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-----重啓iptables服務
2）關閉selinux防火牆
[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)安裝依賴包
[root@db ~]#yum -y install gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel openldap openldap-devel openldap-clients openldap-servers make libtool* git tree bison pcre-devel perl gd gd-devel
4）編譯安裝其他軟件
A：安裝libiconv軟件（該軟件支持編碼轉換爲函數）
[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 && make install
[root@db libiconv-1.14]# echo $?
0
（顯示0，表示軟件編譯安裝成功了）
B：安裝libmcrypt （加密算法擴展庫，支持DES, 3DES, RIJNDAEL, Twofish, IDEA, GOST, CAST-256, ARCFOUR, SERPENT, SAFER+等算法)
[root@db software]# tar xf libmcrypt-2.5.7.tar.gz
[root@db software]# cd libmcrypt-2.5.7
[root@db libmcrypt-2.5.7]# ./configure
[root@db libmcrypt-2.5.7]# cd libltdl/
[root@db libltdl]# ./configure --enable-ltdl-install
[root@db libltdl]# make && make install
C: 安裝mhash（mhash的可以用於創建校驗數值，消息摘要，消息認證碼，以及無需原文的關鍵信息保存）
[root@db software]# tar xf mhash-0.9.9.9.tar.gz
[root@db software]# cd mhash-0.9.9.9
[root@db mhash-0.9.9.9]# ./configure && make && make install
D：安裝mcript（mcrypt 是 php 裏面重要的加密支持擴展庫，Mcrypt擴展庫可以實現加密解密功能，就是既能將明文加密，也可以密文還原。）
[root@db software]# tar xf mcrypt-2.6.8.tar.gz
[root@db software]# cd mcrypt-2.6.8
[root@db mcrypt-2.6.8]# export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH
[root@db mcrypt-2.6.8]# ./configure && make && make install
E：增加庫文件
[root@db software]# ln -s /usr/local/lib/libmcrypt.la /usr/lib/libmcrypt.la [root@db software]# ln -s /usr/local/lib/libmcrypt.so /usr/lib/libmcrypt.so [root@db software]# ln -s /usr/local/lib/libmcrypt.so.4 /usr/lib/libmcrypt.so.4 [root@db software]# ln -s /usr/local/lib/libmcrypt.so.4.4.8 /usr/lib/libmcrypt.so.4.4.8 [root@db software]# ln -s /usr/local/lib/libmhash.a /usr/lib/libmhash.a [root@db software]# ln -s /usr/local/lib/libmhash.la /usr/lib/libmhash.la [root@db software]# ln -s /usr/local/lib/libmhash.so /usr/lib/libmhash.so [root@db software]# ln -s /usr/local/lib/libmhash.so.2 /usr/lib/libmhash.so.2 [root@db software]# ln -s /usr/local/lib/libmhash.so.2.0.1 /usr/lib/libmhash.so.2.0.1 [root@db software]# ln -s /usr/local/bin/libmcrypt-config /usr/bin/libmcrypt-configF：安裝cmake （MySQL從5.5版本開始，通過./configure進行編譯配置方式已經被取消，取而代之的是cmake工具）
[root@db ~]# yum -y install cmake
二、安裝mysql數據軟件
1）創建mysql用戶
[root@db software]#groupadd -r mysql
[root@db software]# useradd -r -g mysql mysql -s /sbin/nologin
2）創建mysql的數據目錄
[root@db software]# mkdir -p /data/mysqldb
3）安裝mysql
[root@db ~]# cd /software/
[root@db software]# tar xf mysql-5.5.51-linux2.6-x86_64.tar.gz -C /usr/local/
[root@db software]# cd /usr/local/
[root@db local]# ll
total 48

drwxr-xr-x. 2 root root 4096 Sep 23 2011 etc

drwxr-xr-x. 8 root root 4096 Aug 18 11:41 share
drwxr-xr-x. 2 root root 4096 Sep 23 2011 src
[root@db local]# ln -sv mysql-5.5.51-linux2.6-x86_64/ mysql
`mysql' -> `mysql-5.5.51-linux2.6-x86_64/'
修改mysql目錄權限
[root@db mysql]# chown -R mysql:mysql .
[root@db mysql]# cd /data/mysqldb/
[root@db mysqldb]# chown -R mysql:mysql .
初始化mysql數據庫
[root@db ~]# cd /usr/local/mysql
[root@db mysql]# ./scripts/mysql_install_db --user=mysql --datadir=/data/mysqldb
編輯mysql配置文件/etc/my.cnf
[mysqld]
datadir=/data/mysqldb
socket=/tmp/mysql.sock
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
複製MySQL啓動文件及其命令加入PATH
[root@db mysql]# cp support-files/mysql.server /etc/init.d/mysqld
[root@db mysql]# chmod +x /etc/init.d/mysqld
[root@db mysql]# chkconfig mysqld on
[root@db mysql]# vim /etc/profile.d/mysqld.sh
PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH[root@db mysql]# source /etc/profile.d/mysql.sh
啓動mysql服務器
[root@db etc]# service mysqld start
Starting MySQL.. [ OK ]
修改root用戶的密碼及授權普通用戶test可以遠程連接到mysql數據庫
mysql> grant all on *.* to 'root'@'localhost' identified by 'test123';
Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
mysql> grant all on *.* to 'test'@'%' identified by 'test1234';
Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec
