搭建LNMP

安装部署LNMP

一:安装nginx 服务

1.1 关闭防火墙和selinux

systemctl restart firewalld 
systemctl disable  firewalld 
setenforce 0
 vim /etc/selinux/config 
SELINUX=disabled

1.2 安装依赖包,上传软件包到 /opt/目录

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

搭建LNMP


1.3 创建运行用户

useradd -M -s /sbin/nologin nginx

1.4 编译安装

#需要将nginx 源码包上传到/opt目录下
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


1.5 优化路径

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

1.6 添加nginx 服务

如果使用免交互,要注意有变量,不可以让变量被替换

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

1.7 访问测试

firefox http://192.168.23.103

搭建LNMP


二: 安装mysql 服务

2.1 安装mysql 环境依赖包,上传软件包到/opt/目录

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

搭建LNMP


2.2 创建运行用户

useradd -M -s /sbin/nologin  mysql

2.3 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  \

-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

2.4 修改mysql 配置文件

#centos 7默认有 /etc/my.cnf,这是mariadb数据库的安装文件,可以先删除

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

2.5 修改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

2.6 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

搭建LNMP


2.7 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

搭建LNMP


2.8 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

2.9 修改mysql 登录密码

mysqladmin -u root -p password "abc123"

搭建LNMP


2.10 授权远程登录

mysql -u root -p"abc123" -e "grant all privileges on *.* to 'root'@'%' identified by 'abc123';"

搭建LNMP


交互式修改root密码

mysql -u root -p  #先初始空密码登录,当要求输入密码,直接回车

#修改root密码
set password for 'root'@'localhost'=password('abc123');
#远程登录可选
set password for 'root'@'%'=password('abc123');
#授权远程登录
grant all privileges on *.* to 'root'@'%' identified by 'abc123';

三: 安装配置PHP

3.1 上传软件包到/opt/目录下,并安装依赖包

yum -y install gd \
libjpeg libjpeg-devel \
libpng libjpeg-turbo-devel  \
freetype freetype-devel \
libxml2 libxml2-devel \
zlib zlib-devel \
curl curl-devel \
openssl openssl-devel

搭建LNMP


3.2 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

#php -m 可以查看安装的模块

3.3 路径优化

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

3.4 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

3.4.1 调整主配置文件

cp /opt/php-7.1.10/php.ini-development /usr/local/php/lib/php.ini
cp /usr/local/php/lib/php.ini{,.bak}

#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

3.4.2 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

搭建LNMP


3.4.3 调整扩展配置文件

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

#因为在进程服务配置文件里有   include=/usr/local/php/etc/php-fpm.d/*.conf  项

搭建LNMP


3.5 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

搭建LNMP


3.6 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
	include        fastcgi_params;
}


systemctl restart nginx.service

搭建LNMP


3.7 验证php测试页面

7、验证PHP 测试页
vim /usr/local/nginx/html/index.php
<?php
phpinfo();
?>

浏览器访问
http://192.168.80.10/index.php

搭建LNMP


3.8 测试数据库工作是否正常

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
<?php
$link=mysqli_connect('192.168.23.103','bbsuser','admin123');
if($link) echo "<h1>Success!!</h1>";
else echo "Fail!!";
?>



#浏览器访问
http://192.168.23.103/index.php

搭建LNMP


四 部署社区论坛web应用

4.1 将软件包上传到/opt目录下

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/

搭建LNMP


4.2 调整论坛目录的权限

cd /usr/local/nginx/html/bbs/
chown -R nobody ./config/
chown -R nobody ./data/
chown -R nobody ./uc_client/
chown -R nobody ./uc_server/

或
chmod -R 777 ./config/
chmod -R 777 ./data/
chmod -R 777 ./uc_client/
chmod -R 777 ./uc_server/

#这里是使用了 php-fpm,启动用户是nobody

搭建LNMP


4.3 访问论坛页面

firefox http://192.168.23.103/bbs/install/index.php

数据库服务器:localhost     ###本地架设就用localhost,如何不是在在本机上就要填写IP地址和端口号
数据库名字:bbs
数据库用户名:bbsuser
数据库密码:admin123
管理员账号:admin
管理员密码:admin123

五 fpm 参数优化

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
