LNMP安装

安装 Nginx 服务

1、关闭防火墙

[root@localhost ~]# systemctl stop firewalld
[root@localhost ~]# systemctl disable firewalld
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
[root@localhost ~]# setenforce 0

2、安装依赖包

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

3、创建运行用户

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

4、编译安装

[root@localhost ~]# cd /opt/
[root@localhost opt]# tar zxvf nginx-1.12.0.tar.gz -C /opt/

[root@localhost opt]# cd nginx-1.12.0/
[root@localhost nginx-1.12.0]# ./configure \
> --prefix=/usr/local/nginx \
> --user=nginx \
> --group=nginx \
> --with-http_stub_status_module

[root@localhost nginx-1.12.0]# make && make install

5、优化路径

[root@localhost nginx-1.12.0]# ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin/

6、添加 Nginx 系统服务

[root@localhost nginx-1.12.0]# vim /lib/systemd/system/nginx.service

[Unit]
Description=nginx

[root@localhost nginx-1.12.0]# chmod 754 /lib/systemd/system/nginx.service
[root@localhost nginx-1.12.0]# systemctl start nginx.service
[root@localhost nginx-1.12.0]# systemctl enable nginx.service

安装 MySQL 服务

1、安装Mysql环境依赖包

[root@localhost ~]# yum -y install \
> ncurses \
> ncurses-devel \
> bison \
> cmake

2、创建运行用户

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

3、编译安装

[root@localhost ~]# cd /opt
[root@localhost opt]# tar zxvf mysql-boost-5.7.20.tar.gz

[root@localhost opt]# cd /opt/mysql-5.7.20/
[root@localhost mysql-5.7.20]# cmake \

[root@localhost mysql-5.7.20]# make -j 4 && make install

4、修改mysql 配置文件

[root@localhost mysql-5.7.20]# vim /etc/my.cnf

[client]
port = 3306
socket=/usr/local/mysql/mysql.sock

[mysqld]
user = mysql
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
port = 3306
character-set-server=utf8
pid-file = /usr/local/mysql/mysqld.pid
socket=/usr/local/mysql/mysql.sock
bind-address = 0.0.0.0
skip-name-resolve
max_connections=2048
default-storage-engine=INNODB
max_allowed_packet=16M
server-id = 1

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

5、更改mysql安装目录和配置文件的属主属组

[root@localhost mysql-5.7.20]# chown -R mysql:mysql /usr/local/mysql/
[root@localhost mysql-5.7.20]# chown mysql:mysql /etc/my.cnf

6、设置路径环境变量

[root@localhost mysql-5.7.20]# echo 'export PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH' >> /etc/profile
[root@localhost mysql-5.7.20]# source /etc/profile

7、初始化数据库

[root@localhost mysql-5.7.20]# cd /usr/local/mysql/bin/
[root@localhost bin]# ./mysqld \
> --initialize-insecure \
> --user=mysql \
> --basedir=/usr/local/mysql \
> --datadir=/usr/local/mysql/data

8、添加mysqld系统服务

[root@localhost bin]# cp /usr/local/mysql/usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system/
[root@localhost bin]# systemctl daemon-reload
[root@localhost bin]# systemctl start mysqld.service
[root@localhost bin]# systemctl enable mysqld
Created symlink from /etc/systemd/system/multi-user.target.wants/mysqld.service to /usr/lib/systemd/system/mysqld.service.

9、修改mysql 的登录密码

[root@localhost bin]# mysqladmin -u root -p password "abc123"
Enter password:

10、授权远程登录

[root@localhost bin]# mysql -u root -p
Enter password: 

mysql> 

安装配置 PHP 解析环境

1、安装环境依赖包

[root@localhost bin]# yum -y install gd \
> libjpeg libjpeg-devel \
> libpng libpng-devel \
> freetype freetype-devel \
> libxml2 libxml2-devel \
> zlib zlib-devel \
> curl curl-devel \
> openssl openssl-devel

2、编译安装

[root@localhost ~]# cd /opt/
[root@localhost opt]# tar jxvf php-7.1.10.tar.bz2

[root@localhost opt]# cd php-7.1.10
[root@localhost php-7.1.10]# ./configure \
> --prefix=/usr/local/php \
> --with-mysql-sock=/usr/local/mysql/mysql.sock \
> --with-mysqli \
> --with-zlib \
> --with-curl \
> --with-gd \
> --with-jpeg-dir \
> --with-png-dir \
> --with-freetype-dir \
> --with-openssl \
> --enable-fpm \
> --enable-mbstring \
> --enable-xml \
> --enable-session \
> --enable-ftp \
> --enable-pdo \
> --enable-tokenizer \
> --enable-zip

[root@localhost php-7.1.10]# make -j2 && make install

3、路径优化

[root@localhost php-7.1.10]# ln -s /usr/local/php/bin/* /usr/local/bin/
[root@localhost php-7.1.10]# ln -s /usr/local/php/sbin/* /usr/local/sbin/

4、调整PHP配置文件

调整主配置文件：

[root@localhost ~]# cp /opt/php-7.1.10/php.ini-development /usr/local/php/lib/php.ini
[root@localhost ~]# vim /usr/local/php/lib/php.ini

--1170行--修改
mysqli.default_socket = /usr/local/mysql/mysql.sock
--939行--取消注释，修改
date.timezone = Asia/Shanghai
[root@localhost ~]# php -m 

调整进程服务配置文件：

[root@localhost ~]# cd /usr/local/php/etc/
[root@localhost etc]# cp  php-fpm.conf.default php-fpm.conf
[root@localhost etc]# vim php-fpm.conf

--17行--去掉";"注释
pid = run/php-fpm.pi

调整扩展配置文件：

[root@localhost etc]# cd /usr/local/php/etc/php-fpm.d/
[root@localhost php-fpm.d]# cp www.conf.default www.conf

5、启动php-fpm

[root@localhost php-fpm.d]# /usr/local/php/sbin/php-fpm -c /usr/local/php/lib/php.ini
[root@localhost php-fpm.d]# netstat -anpt | grep 9000
tcp        0      0 127.0.0.1:9000          0.0.0.0:*               LISTEN      42128/php-fpm: mast 
[root@localhost php-fpm.d]# cd /opt/php-7.1.10/sapi/fpm
[root@localhost fpm]# cp php-fpm.service /usr/lib/systemd/system/php-fpm.service
[root@localhost fpm]# systemctl restart php-fpm.service

6、配置 Nginx 支持 PHP 解析

[root@localhost fpm]# vim /usr/local/nginx/conf/nginx.conf

--65行--取消注释，修改
location ~ \.php$ {
	root           html;
	fastcgi_pass   127.0.0.1:9000;
	fastcgi_index  index.php;
	fastcgi_param  SCRIPT_FILENAME  /usr/local/nginx/html$fastcgi_script_name;	#将 /scripts 修改为nginx的工作目录
   #fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;  #$document_root 代表当前请求在root指令中指定的值
	include        fastcgi_params;
}

[root@localhost fpm]# systemctl restart nginx.service

7、验证PHP 测试页

[root@localhost fpm]# vim /usr/local/nginx/html/index.php

<?php
phpinfo();
?>

8、验证数据库工作是否正常

[root@localhost ~]# mysql -u root -p
Enter password:
