LNMP服务

lnmp是指一组通常一起使用来运行动态网站或者服务器的自由软件名称首字母缩写。L指Linux，N指Nginx，M一般指MySQL，也可以指MariaDB，P一般指PHP，也可以指Perl或Python

lnmp代表的就是：Linux系统下Nginx+MySQL+PHP这种网站服务器架构

• LNMP服务
• • Nginx
  • Mysql
  • PHP
  • 测试
  • fpm参数优化
  • LNMP一键部署脚本

systemctl stop firewalld				#关闭防火墙
systemctl disable firewalld
setenforce 0							#关闭Selinux

1、安装依赖包

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

2、创建运行用户

useradd -M -s /sbin/nologin nginx

3、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

4、优化路径

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

5、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			#赋予权限
systemctl start nginx.service						#启动nginx
systemctl enable nginx.service

1、安装Mysql环境依赖包

yum -y install 
ncurses 
ncurses-devel 
bison 
cmake

2、创建运行用户

useradd -M -s /sbin/nologin  mysql

3、编译安装

cd /opt
tar zxvf mysql-boost-5.7.20.tar.gz
mkdir -p /usrlocal/mysql

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 
-DWITH_SYSTEMD=1

make && make install

4、修改mysql 配置文件

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

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

6、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

7、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

8、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

9、修改mysql 的登录密码

mysqladmin -u root -p password "abc123"

10、授权远程登录

mysql -u root -p

1、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

2、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 && make install

3、路径优化

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

4、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.conf		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
--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

5、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，需要由 Nginx 把动态请求交给 php-fpm 进程进行解析。

cd /opt/php-7.1.10/sapi/fpm
cp php-fpm.service /usr/lib/systemd/system/php-fpm.service
systemctl restart php-fpm.service

6、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
   #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;
}

systemctl restart nginx.service

7、验证PHP 测试页

vim /usr/local/nginx/html/index.php


浏览器访问
http://192.168.237.138/index.php

8、验证数据库工作是否正常

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;

vim /usr/local/nginx/html/index.php      		#替换原来的测试页内容


浏览器访问
http://192.168.237.138/index.php

部署 Discuz，社区论坛 Web 应用

cd /opt
unzip Discuz_X3.4_SC_UTF8.zip  -d /opt/dis
cd /opt/dis/dir_SC_UTF8/
cp -r upload/ /usr/local/nginx/html/bbs/

调整论坛目录的权限：
cd /usr/local/nginx/html/bbs/
chown -R nginx ./config/
chown -R nginx ./data/
chown -R nginx ./uc_client/
chown -R nginx ./uc_server/
或
chmod -R 777 ./config/
chmod -R 777 ./data/
chmod -R 777 ./uc_client/
chmod -R 777 ./uc_server/

论坛页面访问
http://192.168.237.138/bbs/install/index.php

vim /usr/local/php/etc/php-fpm.conf 
pid = run/php-fpm.pid

vim /usr/local/php/etc/php-fpm.d/www.conf
--96行--
pm = dynamic				#fpm进程启动方式，动态的
--107行--
pm.max_children=20			#fpm进程启动的最大进程数
--112行--
pm.start_servers = 5		#动态方式下启动时默认开启的进程数，在最小和最大之间
--117行--
pm.min_spare_servers = 2	#动态方式下最小空闲进程数
--122行--
pm.max_spare_servers = 8	#动态方式下最大空闲进程数

kill -USR2 `cat /usr/local/php/var/run/php-fpm.pid`			#重启php-fpm
netstat -anpt | grep 9000
ps -elf | grep php-fpm

前提：需把源码包提前放入opt目录下，并根据自己源码包的版本，更换脚本中版本

#！/bin/bash

systemctl stop firewalld
systemctl disable firewalld
setenforce 0

echo "现在开始安装nginx"
yum -y install pcre-devel zlib-devel gcc gcc-c++ make

useradd -M -s /sbin/nologin nginx

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

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

cat >/lib/systemd/system/nginx.service < /etc/my.cnf <> /etc/profile </usr/local/nginx/html/index.php <
