LNMP-compile and install architecture

One, LNMP architecture

1. Install Nginx

Prepare the software package

cd /opt
放入软件包
systemctl stop firewalld
systemctl disable firewalld
setenforce 0
yum -y install pcre-devel zlib-devel gcc gcc-c++ make

3. Create and run users and groups and compile and install Nginx

(The Nginx service program runs as nobody by default. It is recommended to create a special user account for it to control its access permissions more accurately)

useradd -M -s /sbin/nologin nginx

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

cd nginx-1.12.0/
./configure \
--prefix=/usr/local/nginx \				      #指定nginx的安装路径
--user=nginx \										#指定用户名
--group=nginx \										#指定组名
--with-http_stub_status_module						#启用 http_stub_status_module 模块以支持状态统计
./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/		#让系统识别nginx的操作命令

3. Check, start, restart, and stop the nginx service

nginx -t								#检查配置文件是否配置正确
nginx							#启动		

查看nginx的进程号
四种方式
cat /usr/local/nginx/logs/nginx.pid 
ss -ntpl | grep 80        //推荐使用，读取速度快
netstat -natp | grep 80
netstat -natp | grep nginx
lsof -i :80

kill -3 <PID号>
kill -s QUIT <PID号>				#停止
killall -3 nginx
killall -s QUIT nginx

kill -1 <PID号>					#重载
kill -s HUP <PID号>
killall -1 nginx
killall -s HUP nginx
#日志分隔，重新打开日志文件
kill -USR1 <PID号>
#平滑升级
kill -USR2 <PID号>

4. Add Nginx system service

method one:

vim /etc/init.d/nginx
#!/bin/bash
#chkconfig: - 99 20
#description:Nginx Service Control Script
COM="/usr/local/nginx/sbin/nginx"
PID="/usr/local/nginx/logs/nginx.pid"
case "$1" in
start)
  $COM
;;

stop)
  kill -s QUIT $(cat $PID)
;;

restart)
  $0 stop
  $0 start
;;

reload)
  kill -s HUP $(cat $PID)
;;

*)
echo "Usage: $0 {start|stop|restart|reload}"
exit 1

esac
exit 0


chmod +x /etc/init.d/nginx
chkconfig --add nginx							#添加为系统服务
systemctl stop nginx
systemctl start nginx

Method Two:

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
ExecrReload=/bin/kill -s HUP $MAINPID
ExecrStop=/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

Two, install MySQL service

1. Install the Mysql environment dependency package and create a user

yum -y install \
ncurses \
ncurses-devel \
bison \
cmake
或者：
yum -y install  ncurses ncurses-devel bison cmake
useradd -M -s /sbin/nologin mysql

2. Compile and install Mysql

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_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    //编译安装

3. Adjust the permissions of the mysql data directory

chown -R mysql:mysql /usr/local/mysql

vim /etc/my.cnf

[client]
port = 3306
default-character-set=utf8
socket = /usr/local/mysql/mysql.sock

[mysql]
port = 3306
default-character-set=utf8
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
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

4. Set environment variables, and output, refresh the file

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

5. Initialize the data file

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

mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

6. Use systemctl for service control and restart the service

cp /usr/local/mysql/usr/lib/systemd/system/mysqld.service /lib/systemd/system/
systemctl daemon-reload
systemctl start mysqld.service  #开启服务
systemctl enable mysqld         #开机自启动
netstat -anpt | grep 3306       #查看端口

7. Set the password of the mysql database and log in

mysqladmin -u root -p password "123"

mysql -u root -p 
grant all privileges on *.* to 'root'@'%' identified by '123';
#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

Three, install PHP

1. Decompress and install the dependency package

tar jxvf php-7.1.10.tar.bz2

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

3. Configure the module

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

4. Modify the installation file

1.路径优化
ln -s /usr/local/php/bin/* /usr/local/bin/
ln -s /usr/local/php/sbin/* /usr/local/sbin/
2.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 
//在测试环境时使用php.ini-development文件，而在生产环境时使用php.ini-production文件
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

//调整扩展配置匹配文件
cd /usr/local/php/etc/php-fpm.d/
cp www.conf.default www.conf

5. Start php-fpm, configure Nginx to support PHP parsing

PHP-FPM (FastCGI Process Manager: FastCGI Process Manager) is a PHPFastCGI manager. Since the Nginx server cannot handle dynamic pages, Nginx needs to pass dynamic requests to the php-fpm process for analysis.

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

vim /usr/local/nginx/conf/nginx.conf
——65行——取消注释，修改

ocation ~ \.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;
        }

6. Create a home page and restart nginx

vim /usr/local/nginx/html/index.php
//可以改成显示php配置的web网页
<?php
phpinfo();
?>

systemctl restart nginx
http://192.168.221.15/index.php
