linux系统架构-----LNMP
LNMP概述
- LNMP为Linux平台，Nginx web服务软件，mysql数据库软件，PHP编辑语言
- LNMP系统架构相对于LAMP的优点是LNMP比较节省内存，主要支持静态请求，但在访问量大的时候php-fpm容易僵死，容易发生502 bad gateway错误，LAMP适合处理动态请求
一安装nginx
//将安装包挂载mnt目录下
mount.cifs //192.168.10.138/LNMP-C7 /mnt将安装包解压到opt目录下 安装环境包
tar zxvf nginx-1.12.2.tar.gz -C /opt
yum install gcc gcc-c++ pcre* zlib-devel make -y创建nginx用户
useradd -M -s /sbin/nologin nginx安装nginx
cd /opt/nginx-1.12.2/
./configure \
--prefix=/usr/local/nginx \
--user=nginx \
--group=nginx \
--with-http_stub_status_module编译
make && make install优化nginx
//为nginx创建软连接
ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin
//创建service工具
vim /etc/init.d/nginx
#!/bin/bash
#chkconfig: - 99 20
#description: Nginx Server Control Script
PROG="/usr/local/nginx/sbin/nginx"
PIDF="/usr/local/nginx/logs/nginx.pid"
case "$1" in

kill -s QUIT $(cat $PIDF)

kill -s HUP $(cat $PIDF)
;;
*)
echo "Usage: $0 {start|stop|restart|reload}"
exit 1
esac
exit 0
//添加权限
chmod +x /etc/init.d/nginx
//添加为系统服务
chkconfig --add /etc/init.d/nginx 关闭防火墙 增强性功能 开启nginx服务
systemctl stop firewalld.service
setenforce 0
service nginx start第二步安装MYSQL
解压安装包
tar -xzvf mysql-boost-5.7.20.tar.gz -C /opt安装环境包
yum install ncurses ncurses-devel bison cmake autoconf -y创建用户
useradd -s /sbin/nologin mysql
安装配置环境
cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock \
-DSYSCONFDIR=/etc \
-DSYSTEMD_PID_DIR=/usr/local/mysql \

-DWITH_PERFSCHEMA_STORAGE_ENGINE=1 \
-DMYSQL_DATADIR=/usr/local/mysql/data \
-DWITH_BOOST=boost \
-DWITH_SYSTEMD=1编译
make && make install
调整MySQL数组
chown -R mysql:mysql /usr/local/mysql
调整配置文件参数
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设置环境变量
echo 'PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH' >> /etc/profile
//设置全局变量
echo 'export PATH' >> /etc/profile
//启动文件
source /etc/profile初始数据库
cd /usr/local/mysql
bin/mysqld \
--initialize-insecure \
--user=mysql \
--basedir=/usr/local/mysql \
--datadir=/usr/local/mysql/data优化mysql服务控制，使用systemctl工具控制mysql服务
cp /usr/local/mysql/usr/lib/systemd/system/mysqld.service /lib/systemd/system
开启mysql服务
systemctl start mysqld.service设置数据库密码
mysqladmin -u root -p password安装php
将安装包解压到opt
tar xjvf php-7.1.10.tar.bz2 -C /opt安装环境包
yum -y install \
libjpeg \
libjpeg-devel \
libpng libpng-devel \
freetype freetype-devel \
libxml2 \
libxml2-devel \
zlib zlib-devel \
curl curl-devel \
openssl openssl-devel配置服务，安装且编译
./configure \
--prefix=/usr/local/php \
--with-mysql-sock=/usr/local/mysql/mysql.sock \
--with-mysqli \
--with-zlib \
--with-curl \
--with-gd \
--with-jpeg-dir \
--with-png-dir \
--with-freetype-dir \
--with-openssl \
--enable-fpm \
--enable-mbstring \
--enable-xml \
--enable-session \
--enable-ftp \
--enable-pdo \
--enable-tokenizer \
--enable-zip编译
make && make install拷贝核心配置文件
cp php.ini-development /usr/local/php/lib/php.ini编辑核心配置文件
vim /usr/local/php/lib/php.ini
#指定路经
mysqli.default_socket = /usr/local/mysql/mysql.sock
date.timezone = Asia/Shanghai
验证模块
/usr/local/php/bin/php -m配置FPM模块
cd /usr/local/php/etc/
cp php-fpm.conf.default php-fpm.conf
vim php-fpm.conf
#去掉注释
pid = run/php-fpm.pid启动php
/usr/local/php/sbin/php-fpm -c /usr/local/php/lib/php.ini建立软链接
vim /usr/local/nginx/conf/nginx.conf
ln -s /usr/local/php/bin/* /usr/local/bin/使得Nginx支持PHP
location ~ \.php$ {
#指定站点目录
root html;
#FPM模块的位置
fastcgi_pass 127.0.0.1:9000;
#支持php的网页格式
fastcgi_index index.php;
#加载脚本类型和位置
fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html$fastcgi_script_name;
#把nginx中的变量转化为php中的变量
include fastcgi_params;
}创建PHP首页，且重启nginx服务
vim /usr/local/nginx/html/index.php
<?
phpphpinfo();
?>
systemctl restart nginx
