LNMP(Linux、MySQL、Nginx、PHP)

安装Nginx服务

systemctl stop firewalld
systemctl disable firewalld
setenforce 0

安装依赖包
在安装前要查看是否配置了yum本地仓库源

yum -y install pcre-devel zlib-devel gcc gcc-c++ make

创建运行用户

useradd -M -s /sbin/nologin nginx 

编译安装

cd /opt
tar zxvf nginx-1.12.0.tar.gz -C /opt/

cd nginx-1.12.0/
./configure \
--prefix=/usr/local/nginx \
--user=nginx \
--group=nginx \
--with-http_stub_status_module

make && make install

优化路径

ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin/

添加nginx系统服务

vim /lib/systemd/system/nginx.service

[Unit]
Description=nginx
After=network.target
[Service]
Type=forking
PIDFile=/usr/local/nginx/logs/nginx.pid
ExecStart=/usr/local/nginx/sbin/nginx
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true
[Install]
WantedBy=multi-user.target

chmod 754 /lib/systemd/system/nginx.service
systemctl start nginx.service
systemctl enable nginx.service

安装MySQL服务

安装MySQL环境依赖包

yum -y install \
ncurses \
ncurses-devel \
bison \
cmake

创建运行用户

useradd -M -s /sbin/nologin mysql

编译安装

cd /opt
tar zxvf mysql-boost-5.7.20.tar.gz

cd /opt/mysql-5.7.20/
cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock \
-DSYSCONFDIR=/etc \
-DSYSTEMD_PID_DIR=/usr/local/mysql \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_EXTRA_CHARSETS=all \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_ARCHIVE_STORAGE_ENGINE=1 \
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
-DWITH_PERFSCHEMA_STORAGE_ENGINE=1 \
-DMYSQL_DATADIR=/usr/local/mysql/data \
-DWITH_BOOST=boost \  (这个和lamp不一样，且不能改)
-DWITH_SYSTEMD=1

make -j 2 && make install

修改MySQL配置文件

vim /etc/my.cnf   (原文档全删)
[client]
port = 3306        #等号两边要有空格
socket=/usr/local/mysql/mysql.sock

更改MySQL安装目录和配置文件的属主属组

chown -R mysql:mysql /usr/local/mysql/
chown mysql:mysql /etc/my.cnf

设置路径环境变量

echo 'export PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH' >> /etc/profile
source /etc/profile

初始化数据库

cd /usr/local/mysql/bin/
./mysqld \
--initialize-insecure \
--user=mysql \
--basedir=/usr/local/mysql \
--datadir=/usr/local/mysql/data \
--collation-server=utf8_general_ci

添加mysqld系统服务

cp /usr/local/mysql/usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system/
systemctl daemon-reload
systemctl start mysqld.service
systemctl enable mysqld

修改mysql的登陆密码

mysqladmin -u root -p password "abc123"
Enter password:  #直接回车

授权远程登录

mysql -u root -p

grant all privileges on *.* to 'root'@'%' identified by 'abc123';        （有分号）
#授予root用户可以在所有终端远程登录，使用的密码是abc123，并对所有数据库和所有表有操作权限
show databases;			 查看当前已有的数据库

安装配置PHP解析环境

安装环境依赖包

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

编译安装

cd /opt
tar jxvf php-7.1.10.tar.bz2

cd 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

make -j 2 && make install

路径优化

ln -s /usr/local/php/bin/* /usr/local/bin/

调整php配置文件
php有三个配置文件
php.ini 主配置文件
php-fpm.conf 进程服务配置文件
www.cong 扩展配置文件

调整主配置文件

cp /opt/php-7.1.10/php.ini-development /usr/local/php/lib/php.ini
vim /usr/local/php/lib/php.ini
1170行修改
mysqli.default_socket = /usr/local/mysql/mysql.sock    #注意空格
939行取消注释，修改
date.timezone = Asia/Shanghai
php -m               验证安装的模块

调整进程服务配置文件

cd /usr/local/php/etc/
cp php-fpm.conf.default php-fpm.conf
vim php-fpm.conf
17行去掉“；”注释
pid = run/php-fpm.pid

调整扩展配置文件

cd /usr/local/php/etc/php-fpm.d/
cp www.conf.default www.conf

启动php-fpm

/usr/local/php/sbin/php-fpm -c /usr/local/php/lib/php.ini
netstat -anpt | grep 9000

PHP-FPM(FastCGI Process Manager:FastCGI进程管理器)是一个PHPFastCGI管理器，
由于nginx服务器不能处理动态页面，需要nginx把动态请求交给php-fpm进程进行解析

配置nginx支持php解析

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
include            fastcgi_params;
}

systemctl restart nginx.service

验证php测试页

vim/usr/local/nginx/html/index.php
<?php
phpinfo();
?>

浏览器访问

http://192.168.238.40/index.php

创建数据库，并进行授权

mysql -u root -p
CREATE DATABASE bbs;
GRANT all ON bbs.* To 'bbsuser'@'%' IDENTIFIED BY 'admin123';
GRANT all ON bbs.* To 'bbsuser'@'localhost' IDENTIFIED BY 'admin123';
flush privileges;
show databases;

vim /usr/local/nginx/html/index.php   #替换原来的测试页内容
<?php
$link=mysqli_connect ('192.168.238.40','bbsuser','admin123');
if ($link) echo "<h1>Success!!</h1>";
else echo "Fail!!";
?>

浏览器访问

http://192.168.238.40/index.php
