LNMP搭建

LNMP

• 一、安装Nginx服务
• 二、安装Mysql服务
• 三、安装配置PHP解析环境
• 四、部署 Discuz！社区论坛 Web 应用

一、安装Nginx服务

systemctl stop firewalld
systemctl disable firewalld
setenforce 0

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
systemctl start Nginx.service
systemctl enable Nginx.service

二、安装MysqL服务

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

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

三、安装配置PHP解析环境

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
	include        fastcgi_params;
}

systemctl restart Nginx.service

7、验证PHP 测试页

vim /usr/local/Nginx/html/index.PHP
<?PHP
PHPinfo();
?>

浏览器访问
http://192.168.22.123/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
<?PHP
$link=MysqLi_connect('192.168.22.123','bbsuser','admin123');
if($link) echo "<h1>Success!!</h1>";
else echo "Fail!!";
?>

浏览器访问
http://192.168.22.123/index.PHP

四、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://192.168.22.123/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

访问论坛页面：

http://192.168.22.123/bbs/index.PHP
http://192.168.22.123/bbs/admin.PHP
