1、Centos6系統庫中默認是沒有nginx的rpn包的，所以我們需要先更新下rpm依賴庫
(1)：使用yum安裝nginx，安裝nginx庫
rpm -Uvh http://nginx.org/packages/centos/6/noarch/RPMS/nginx-release-centos-6-0.el6.ngx.noarch.rpm
(2)：使用下面命令安裝nginx
yum -y install nginx
(3)：啟動nginx
service nginx start #centos6
或
systemctl start nginx.service #centos7
(4)：防火牆允許通過80端口
vim /etc/sysconfig/iptables # Generated by iptables-save v1.4.7 on Thu Dec 28 19:47:19 2017 *filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [21691:949300] -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT -A INPUT -p icmp -j ACCEPT -A INPUT -i lo -j ACCEPT -A INPUT -p tcp -m state --state NEW -m tcp --dport 22 -j ACCEPT -A INPUT -p tcp -m state --state NEW -m tcp --dport 80 -j ACCEPT -A INPUT -j REJECT --reject-with icmp-host-prohibited -A FORWARD -j REJECT --reject-with icmp-host-prohibited COMMIT
(5)：重啟防火牆
service iptables restart
(6)：訪問網站，查看是否出現 'Welcome To Nginx'，如果想更改網站根目錄，修改地址：vim /etc/nginx/conf.d/default.conf，修改Root 后面的路徑，詳細請參考：Liscookie
2、安裝Mysql，先更新yum源
(1)：yum源下載地址，根據自己需要的版本選擇相應的源
https://dev.mysql.com/downloads/repo/yum/
(2)：我們版本是6.x的，所以選擇linux 6 下載
wget https://repo.mysql.com//mysql57-community-release-el6-11.noarch.rpm
(3)：安裝mysql的yum源
rpm -Uvh mysql57-community-release-el6-11.noarch.rpm
或
yum -y localinstall mysql57-community-release-el6-11.noarch.rpm
(4)：查看是否配置mysql源成功
在/etc/yum.repos.d下面
(5)：安裝Mysql
yum -y install mysql-community-server #時間有點長，稍微等一下
(6)：開始mysql服務
service mysqld start
(7)：Mysql安裝成功之后，會自動創建root的密碼，存儲在/var/log/mysqld.log，可以通過以下命令來查看
grep 'temporary password' /var/log/mysqld.log
(8)：登錄mysql，修改密碼
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'Wang123!';
(9)：開啟遠程鏈接，iptables開放3306端口
vim /etc/sysconfig/iptables
(10)：重啟防火牆使iptables生效
service iptables restart
3、安裝PHP
(1)：更新yum源
rpm -Uvh http://ftp.iij.ad.jp/pub/linux/fedora/epel/6/x86_64/epel-release-6-8.noarch.rpm
rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
(2)：安裝PHP
yum -y install --enablerepo=remi --enablerepo=remi-php56 php php-bcmath php-opcache php-devel php-mbstring php-mcrypt php-mysqlnd php-gd php-xml php-memcache php-redis php-fpm php-mysql php-common php-mssql
(3)：配置php.ini文件，關閉php信息頭
vim /etc/php.ini #366行左右 expose_php = Off #關閉phpxinxi
(4)：啟動PHP，設置開機啟動
service php-fpm restart #啟動php chkconfig php-fpm --level 2345 on #設置開機啟動
OK，至此，已經安裝完成了LNMP
