CentOS 7.4搭建LNMP环境

之前有一篇博客写的是LAMP的环境搭建，今天来详细介绍一下另外一个模式LNMP=Linux+Nginx+MySQL+PHP。和LAMP不同的是，LNMP中的N指的是Nginx（类似于Apache的一种WEB服务软件），并且PHP是作为一个独立服务存在的，这个服务叫做php-fpm，Nginx直接处理静态请求，动态请求会转发给php-fpm。

目前LNMP环境的应用非常多。在静态页面的处理上，Nginx比Apache更强；但在动态页面的处理上，Nginx并不占优势。

一、目录

• 准备工作
  
• 安装Nginx服务
  
• 安装Mysql服务
  
• 搭建PHP运行环境
  

二、准备工作

1、服务器信息

软件版本：

Nginx：1.13.4

MYSQL：5.7.22

PHP：7.2.9

2、下载软件包

#Nginx软件包

https://mirrors.yangxingzhen.com/nginx/nginx-1.13.4.tar.gz

3、将防火墙与selinux关闭

[root@localhost ~]# systemctl stop firewalld

[root@localhost ~]# systemctl disable firewalld

[root@localhost ~]# sed -i '/SELINUX/s/enforcing/disabled/' /etc/selinux/config

三、安装Nginx服务

1、下载软件包和安装编译工具及依赖包

[root@localhost ~]# yum -y install wget gcc gcc-c++ make pcre-devel pcre perl openssl openssl-devel

[root@localhost ~]# wget -c https://mirrors.yangxingzhen.com/nginx/nginx-1.13.4.tar.gz

2、解压软件包

[root@localhost ~]# tar zxf nginx-1.13.4.tar.gz

3、创建用户和隐藏版本号

[root@localhost nginx-1.13.4]# sed -i 's/1.13.4/ /;s/nginx///nginx/' src/core/nginx.h

[root@localhost nginx-1.13.4]# useradd -s /sbin/nologin www

4、预编译

[root@localhost ~]# cd nginx-1.13.4

[root@localhost nginx-1.13.4]# ./configure --prefix=/usr/local/nginx --user=www --group=www --with-http_ssl_module --with-http_stub_status_module

5、编译及安装

[root@localhost nginx-1.13.4]# make && make install

6、创建软连接

[root@localhost nginx-1.13.4]# ln -s /usr/local/nginx/sbin/nginx /usr/sbin

7、启动Nginx服务

[root@localhost nginx-1.13.4]# nginx -t

[root@localhost nginx-1.13.4]# nginx

8、访问测试

#浏览器访问服务器（192.168.0.117），如下图

四、安装MySQL服务

#MYSQL安装

1、下载boost库（MYSQL5.7及以上需要，必须安装）

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

[root@localhost ~]# wget -c https://mirrors.yangxingzhen.com/mysql/boost_1_59_0.tar.gz

[root@localhost ~]# tar zxf boost_1_59_0.tar.gz -C /usr/local/

2、下载依赖包

[root@localhost ~]# yum -y install ncurses ncurses-devel perl perl-devel gcc gcc-c++ cmake make openssl-devel openssl

3、建立MYSQL用户

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

4、下载MYSQL-5.7.22源码包

[root@localhost ~]# wget -c https://mirrors.yangxingzhen.com/mysql/mysql-5.7.22.tar.gz

[root@localhost ~]# tar zxf mysql-5.7.22.tar.gz

[root@localhost ~]# cd mysql-5.7.22

[root@localhost mysql-5.7.22]# cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql /

-DMYSQL_UNIX_ADDR=/tmp/mysql.sock /

-DMYSQL_DATADIR=/data/mysql /

-DSYSCONFDIR=/etc /

-DENABLED_LOCAL_INFILE=1 /

-DMYSQL_TCP_PORT=3306 /

-DWITH_READLINE=1 /

-DMYSQL_USER=mysql /

-DWITH_SSL=yes

[root@localhost mysql-5.7.22]# make && make install

5、创建MYSQL数据存储目录

[root@localhost mysql-5.7.22]# mkdir -p /data/mysql

[root@localhost mysql-5.7.22]# chown -R mysql.mysql /data/mysql

6、编辑MYSQL主配置文件

[root@localhost mysql-5.7.22]# vim /etc/my.cnf

[client]
default-character-set=utf8
socket = /usr/local/mysql/mysql.sock

[mysql]
port = 3306
default-character-set=utf8
socket = /usr/local/mysql/mysql.sock

[mysqld]
user = mysql
basedir = /usr/local/mysql
datadir = /data/mysql
port = 3306
character_set_server=utf8
pid-file = /usr/local/mysql/mysqld.pid
socket = /usr/local/mysql/mysql.sock
log-error = /tmp/mysqld.log
server-id = 1
log-bin =mysql
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_AUTO_VALUE_ON_ZERO,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,PIPES_AS_CONCAT,ANSI_QUOTES

7、初始化数据库（生成空密码，生成随机密码--initialize）

[root@localhost mysql-5.7.22]# cd /usr/local/mysql/bin

[root@localhost bin]# ./mysqld --initialize-insecure --user=mysql --datadir=/data/mysql --basedir=/usr/local/mysql

8、配置成系统服务

[root@localhost bin]# cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld

[root@localhost bin]# chmod o+x /etc/init.d/mysqld

[root@localhost bin]# chown -R mysql.mysql /usr/local/mysql

[root@localhost bin]# service mysqld start

[root@localhost bin]# chkconfig --add mysqld

[root@localhost bin]# chkconfig mysqld on

[root@localhost bin]# ln -s /usr/local/mysql/bin/* /usr/bin

[root@localhost bin]# mysql

#数据库安装配置成功，退出则输入"quit"

五、安装PHP运行环境

#安装libiconv

1、下载libiconv软件包

[root@localhost ~]# wget -c https://mirrors.yangxingzhen.com/libiconv/libiconv-1.15.tar.gz

2、解压libiconv软件包

[root@localhost ~]# tar zxf libiconv-1.15.tar.gz

[root@localhost ~]# cd libiconv-1.15

3、预编译

[root@localhost libiconv-1.15]# ./configure --prefix=/usr/local/libiconv

    }
    location ~ /.php$ {
    fastcgi_pass 127.0.0.1:9000;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include fastcgi_params;
    }
}
}

#保存退出

7、重启Nginx服务，启动php-fpm服务

[root@localhost html]# nginx -s reload

[root@localhost html]# /usr/local/php/sbin/php-fpm

8、浏览器访问服务器：http://192.168.0.117

9、测试数据库

[root@localhosthtml]# mysql

mysql> create database test;

mysql> grant all on test.* to test@'%' identified by '123456';

mysql> flush privileges;

[root@localhost html]# vim info_mysql.php

<?php
$link=mysqli_connect('192.168.0.117','test','123456');
if($link) echo "<h1>Success!!</h1>";
else echo "Fail!!";
?>

10、访问测试

浏览器访问http://192.168.0.117/info_mysql.php

至此，Liunx环境LNMP环境搭建完毕。
