LNMP架构介绍,MySQL安装,PHP安装,Nginx介绍

LNMP架构介绍

和LAMP不同的是，提供web服务的是Nginx

并且php是作为一个独立服务存在的，这个服务叫做php-fpm

Nginx直接处理静态请求，动态请求会转发给php-fpm

安装顺序是mysql -php -nginx

MySQL安装

# cd /usr/local/src

# wget http://mirrors.sohu.com/mysql/MySQL-5.5/mysql-5.5.60-linux-glibc2.12-x86_64.tar.gz //下载

https://mirrors.huaweicloud.com/mysql/Downloads/MySQL-5.5/mysql-5.5.60-linux-glibc2.12-x86_64.tar.gz 华为镜像源站

# tar zxvf mysql-5.5.60-linux-glibc2.12-x86_64.tar.gz //解压

# mv mysql-5.5.60-linux-glibc2.12-x86_64 /usr/local/mysql 移动到你要放置的目录

# cd /usr/local/mysql

# useradd -s /sbin/nologin mysql -M 新建mysql独立用户

# mkdir /data/ 新建数据库存放目录

# ./scripts/mysql_install_db --user=mysql --datadir=/data/mysql 初始化

报错./bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory

解决办法：# yum install libaio -y

报错FATAL ERROR: please install the following Perl modules before executing scripts/mysql_install_db:

解决办法yum install -y perl perl-devel

# mv /etc/my.cnf /etc/my.cnf.bak

# cp support-files/my-large.cnf /etc/my.cnf

# cp support-files/mysql.server /etc/init.d/mysqld

# vi /etc/init.d/mysqld

定义basedir和datadir

# /etc/init.d/mysqld start //启动服务

# chkconfig --add mysqld 加入到服务列表里面

# chkconfig mysqld on 设置开机启动

PHP安装（上）（下）

和LAMP安装PHP方法有差别，需要开启php-fpm服务

# cd /usr/local/src/ 进入包存放目录

# wget http://mirrors.sohu.com/php/php-5.6.31.tar.gz

# tar -zxvf php-5.6.31.tar.gz

# useradd -s /sbin/nologin php-fpm -M 新建用户并禁止登入

#改账号用来运行php-fpm服务，在lnmp环境中，php以一个服务php-fpm的形式存在，独立存在linux系统中方便管理

# cd php-5.6.31

ps：安装的时候如果没有安装gcc的话就要先安装

# ./configure --prefix=/usr/local/php-fpm --with-config-file-path=/usr/local/php-fpm/etc --enable-fpm --with-fpm-user=php-fpm --with-fpm-group=php-fpm --with-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-pdo-mysql=/usr/local/mysql --with-mysql-sock=/tmp/mysql.sock --with-libxml-dir --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir --with-iconv-dir --with-zlib-dir --with-mcrypt --enable-soap --enable-gd-native-ttf --enable-ftp --enable-mbstring --enable-exif --with-pear --with-curl --with-openssl

报错：

configure: error: xml2-config not found. Please check your libxml2 installation.

# yum install libxml2-devel -y

报错configure: error: Cannot find OpenSSL's <evp.h>

# yum install openssl-devel -y

报错 easy.h should be in <curl-dir>/include/curl/

# yum install -y libcurl-devel

错误configure: error: Please reinstall the BZip2 distribution

# yum install -y bzip2-devel -y

错误：configure: error: jpeglib.h not found.

# yum install -y libjpeg-devel -y

错误configure: error: png.h not found.

# yum install -y libpng-devel -y

错误configure: error: freetype-config not found.

# yum install -y freetype-devel

错误configure: error: mcrypt.h not found. Please reinstall libmcrypt.

# yum install epel-release -y

# yum install -y libmcrypt-devel

然后重新执行下./configure

#make && make install

拷贝配置文件

#cp php.ini-production /usr/local/php-fpm/etc/php.ini 线上用的，，php.ini-development开发用的

定义配置文件php-fpm.conf

# cd /usr/local/php-fpm/etc/

# vi php-fpm.conf

[global]
pid = /usr/local/php-fpm/var/run/php-fpm.pid
error_log = /usr/local/php-fpm/var/log/php-fpm.log
[www]
listen = /tmp/php-fcgi.sock
# 用来定义sock的权限
listen.mode = 666
user = php-fpm
group = php-fpm  
pm = dynamic  
pm.max_children = 50  
pm.start_servers = 20  
pm.min_spare_servers = 5  
pm.max_spare_servers = 35  
pm.max_requests = 500  
rlimit_files = 1024

## /usr/local/php-fpm/sbin/php-fpm -t //验证配置是否正确

出现 test is successful则说明配置文件没有问题，否则需要根据报错提示检查配置文件

# cd /usr/local/src/php-5.6.31

# cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm 拷贝启动文件

# chmod 755 /etc/init.d/php-fpm 设置权限

# chkconfig --add php-fpm 加入开机服务

# chkconfig php-fpm on 开机启动

# service php-fpm start 启动php-fpm

# ps aux |grep php-fpm 检查php-fpm是否启动
