LNMP环境配置（一）

一、安装MySQL

　　这里安装MySQL和之前发过的LAMP配置中安装MySQL步骤一样，就不详细说了。

二、安装PHP

1、下载PHP源码包

2、解压源码包，创建账号：

　　# tar -zxf php-5.6.30.tar.gz

　　# useradd -s /sbin/nologin php-fpm //该账号用来运行php-fpm服务

3、配置编译选项：

　　# cd php-5.6.30

　　#./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-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 --with-gd-native-ttf --enable-ftp --enable-mbstring --enable-exif --disable-ipv6 --with-pear --with-curl --with-openssl

为避免编译时出现错误，请提前安装以下工具：

　　# yum install -y libjpeg-devel

　　# yum install -y libxml2-devel

　　# yum install -y openssl-devel

　　# yum install -y bzip2-devel

　　# yum install -y libpng-devel

　　# yum install -y freetype-devel

　　# yum install -y epel-release

　　# yum install -y libmcrypt-devel

　　# yum install -y gcc

　　# yum install -y libcurl-devel

　　# yum install -y perl-Module-Install

编译PHP:

　　#make && make install

修改配置文件:

　　# cp php.ini-production /usr/local/php-fpm/etc/php.ini

　　# vim /usr/local/php-fpm/etc/php-fpm.conf //写入以下内容

　　[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

　　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

检验配置是否正确：

　　#/usr/local/php-fpm/sbin/php-fpm -t

出现以下内容即为成功：

 

启动php-fpm：

　　# cp /usr/local/src/php-5.6.30/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm

　　# chmod 755 /etc/init.d/php-fpm

　　# service php-fpm start

　　# chkconfig php-fpm on

　　# ps aux |grep php-fpm   //检测php-fpm是否启动

 

三、安装Nginx：

1、下载和解压Nginx：

　　# cd /usr/local/src/

　　# tar -zxf nginx-1.12.2.tar.gz

2、配置编译：

　　# cd nginx-1.12.2

　　# ./configure --prefix=/usr/local/nginx

3、编译和安装：

　　# make && make install

4、编写脚本：

　　# vim /etc/init.d/nginx //写入以下内容　

#!/bin/bash
# chkconfig: - 30 21
# description: http service.
# Source Function Library
. /etc/init.d/functions
# Nginx Settings

NGINX_SBIN="/usr/local/nginx/sbin/nginx"
NGINX_CONF="/usr/local/nginx/conf/nginx.conf"
NGINX_PID="/usr/local/nginx/logs/nginx.pid"
RETVAL=0
prog="Nginx"

start()
{
echo -n $"Starting $prog: "
mkdir -p /dev/shm/nginx_temp
daemon $NGINX_SBIN -c $NGINX_CONF
RETVAL=$?
echo
return $RETVAL
}

stop()
{
echo -n $"Stopping $prog: "
killproc -p $NGINX_PID $NGINX_SBIN -TERM
rm -rf /dev/shm/nginx_temp
RETVAL=$?
echo
return $RETVAL
}

reload()
{
echo -n $"Reloading $prog: "
killproc -p $NGINX_PID $NGINX_SBIN -HUP
RETVAL=$?
echo
return $RETVAL
}

restart()
{
stop
start
}

configtest()
{
$NGINX_SBIN -c $NGINX_CONF -t
return 0
}

case "$1" in
start)
start
;;
stop)
stop
;;
reload)
reload
;;
restart)
restart
;;
configtest)
configtest
;;
*)
echo $"Usage: $0 {start|stop|reload|restart|configtest}"
RETVAL=1
esac

exit $RETVAL

保存脚本后更改权限：

　　# chmod 755 /etc/init.d/nginx

　　# chkconfig --add nginx

　　# chkconfig nginx on

5、更改Nginx配置文件：

　　# > /usr/local/nginx/conf/nginx.conf

　　# vim /usr/local/nginx/conf/nginx.conf //写入以下内容　

user nobody nobody;
worker_processes 2;
error_log /usr/local/nginx/logs/nginx_error.log crit;
pid /usr/local/nginx/logs/nginx.pid;
worker_rlimit_nofile 51200;

events
{
use epoll;
worker_connections 6000;
}

http
{
include mime.types;
default_type application/octet-stream;
server_names_hash_bucket_size 3526;
server_names_hash_max_size 4096;
log_format combined_realip '$remote_addr $http_x_forwarded_for [$time_local]'
' $host "$request_uri" $status'
' "$http_referer" "$http_user_agent"';
sendfile on;
tcp_nopush on;
keepalive_timeout 30;
client_header_timeout 3m;
client_body_timeout 3m;
send_timeout 3m;
connection_pool_size 256;
client_header_buffer_size 1k;
large_client_header_buffers 8 4k;
request_pool_size 4k;
output_buffers 4 32k;
postpone_output 1460;
client_max_body_size 10m;
client_body_buffer_size 256k;
client_body_temp_path /usr/local/nginx/client_body_temp;
proxy_temp_path /usr/local/nginx/proxy_temp;
fastcgi_temp_path /usr/local/nginx/fastcgi_temp;
fastcgi_intercept_errors on;
tcp_nodelay on;
gzip on;
gzip_min_length 1k;
gzip_buffers 4 8k;
gzip_comp_level 5;
gzip_http_version 1.1;
gzip_types text/plain application/x-javascript text/css text/htm
application/xml;

server
{
listen 80;
server_name localhost;
index index.html index.htm index.php;
root /usr/local/nginx/html;

location ~ \.php$
{
include fastcgi_params;
fastcgi_pass unix:/tmp/php-fcgi.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html$fastcgi_script_name;
}
}
}

测试是否有错误：

　　# /usr/local/nginx/sbin/nginx -t

出现以下这两行代码就没有错误：

 

6、启动Nginx：

　　# service nginx start

　　# ps aux |grep nginx

7、测试是否正确解析PHP：

　　# vi /usr/local/nginx/html/2.php

　　<?php

 　　    echo “2222.php”;

　　?>

　　# curl localhost/2.php       //出现下图内容为PHP解析正常
