Centos7 yum安装LNMP

1、Centos7系统库中默认是没有nginx的rpn包的，所以我们需要先更新下rpm依赖库

(1)：使用yum安装nginx，安装nginx库

rpm -Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

(2)：使用下面命令安装nginx

yum -y install nginx

(3)：启动nginx

service nginx start   #centos6
或
systemctl start nginx.service   #centos7

(4)：防火墙允许通过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)：重启防火墙

service iptables restart

(6)：访问网站，查看是否出现 'Welcome To Nginx'，如果想更改网站根目录，修改地址：vim /etc/nginx/conf.d/default.conf，修改Root 后面的路径，详细请参考：Liscookie

2、安装Mysql，先更新yum源

(1)：yum源下载地址，根据自己需要的版本选择相应的源

https://dev.mysql.com/downloads/repo/yum/

(2)：我们版本是6.x的，所以选择linux 6 下载

wget https://repo.mysql.com//mysql57-community-release-el6-11.noarch.rpm

(3)：安装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)：安装Mysql

yum -y install mysql-community-server
#时间有点长，稍微等一下

(6)：开始mysql服务

service mysqld start

(7)：Mysql安装成功之后，会自动创建root的密码，存储在/var/log/mysqld.log，可以通过以下命令来查看

grep 'temporary password' /var/log/mysqld.log

(8)：登录mysql，修改密码

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'Wang123!';

(9)：开启远程链接，iptables开放3306端口

vim /etc/sysconfig/iptables

(10)：重启防火墙使iptables生效

service iptables restart

3、安装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)：安装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，关闭php信息头

vim /etc/php.ini
#366行左右
expose_php = Off #关闭phpxinxi

(4)：启动PHP，设置开机启动

service php-fpm restart #启动php
chkconfig php-fpm --level 2345 on #设置开机启动

OK，至此，已经安装完成了LNMP
