LNMP架构搭建

         LNMP架构搭建及优化

1.1、下载所需要的软件包

# yum install -y wget

# cd /usr/local/src/

#wget http://mirrors.sohu.com/mysql/MySQL-5.1/mysql-5.1.72-linux-i686-glibc23.tar.gz

       # wget http://mirrors.sohu.com/php/php-5.4.44.tar.gz

       # wget http://mirrors.sohu.com/nginx/nginx-1.8.0.tar.gz

1.2、安装配置和编译时所需的软件包

    1、安装扩展yum源 

       # yum install -y epel-release

2、php所需软件包

       # yum install -y  libxml2-devel openssl openssl-devel  bzip2 bzip2-devel  libpng libpng-devel  freetype freetype-devel libjpeg-devel  libcurl-devel libmcrypt-devel gcc

     3、nginx所需软件包

         # yum install -y pcre-devel

1.3、安装mysql

        # tar zxvf mysql-5.1.72-linux-i686-glibc23.tar.gz

        # useradd -M -s /sbin/nologin mysql

        # mkdir -p /data/mysql

        # chown -R mysql:mysql /data/mysql

        # mv mysql-5.1.72-linux-i686-glibc23 /usr/local/mysql

        # cd !$

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

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

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

        # vim /etc/init.d/mysqld   修改内容如下

          basedir=/usr/local/mysql

datadir=/data/mysql

        # chmod 755 /etc/init.d/mysqld

        # chkconfig mysqld on

        # service mysqld start

        # ps aux | grep mysql

        # netstat -lnp| grep mysqld

        # vim /etc/profile.d/path.sh 加入环境变量

           export PATH=$PATH:/usr/local/mysql/bin

        # source !$

1.4、安装php

       # cd /usr/local/src/

       # useradd -M -s /sbin/nologin php-fpm

       # tar zxvf php-5.4.44.tar.gz

       # cd php-5.4.44

# ./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/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 --enable-gd-native-ttf --enable-ftp --enable-mbstring --enable-exif --disable-ipv6 --with-pear --with-curl --with-openssl

# echo $?

# make

# echo $?

# make install

# echo $?

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

# cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm

# chmod 755 /etc/init.d/php-fpm

# vim /usr/local/php/etc/php-fpm.conf

[global]

pid = /usr/local/php/var/run/php-fpm.pid

error_log = /usr/local/php/var/log/php-fpm.log

[www]

listen = /tmp/php-fcgi.sock

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

检测配置文 # /usr/local/php/sbin/php-fpm -t  看到successful表示没有问题

# chkconfig --add php-fpm

# chkconfig php-fpm on

# service php-fpm start

# ps aux|grep php-fpm

1.5、安装nginx

# cd /usr/local/src/

# tar zxvf nginx-1.8.0.tar.gz

# cd nginx-1.8.0

#  ./configure --prefix=/usr/local/nginx --with-http_realip_module --with-http_sub_module --with-http_gzip_static_module --with-http_stub_status_module  --with-pcre

# echo $?

# make

# echo $?

# make install

# /usr/local/nginx/sbin/nginx -t   (测试配置文件，出现ok，successful 表示没问题）

# /usr/local/nginx/sbin/nginx   （启动）

# ps aux | grep nginx

1.6、编写nginx配置文件，使nginx支持php解析

1、修改配置文件

# vim /usr/local/nginx/conf/nginx.conf

找到如下

location / {

root   html;

index  index.html index.htm;

}

在下面添加

location ~ \.php$ {

root           html;

fastcgi_pass   unix:/tmp/php-fcgi.sock;

fastcgi_index  index.php;

fastcgi_param  SCRIPT_FILENAME  /usr/local/nginx/html$fastcgi_script_name;

include        fastcgi_params;

}

2、nginx 加入全局变量

# vim /etc/profile.d/path.sh

# source /etc/profile.d/path.sh

2、检测配置文件是否正确并重新加载

# nginx -t

# nginx -s reload

# service php-fpm restart

3、编写测试php解析文件

# vim /usr/local/nginx/html/info.php

phpinfo();

?>

浏览器访问测试

192.168.230.130/info.php

或者 # curl localhost/info.php -I

1.7、nginx启动脚本和配置文件

1、nginx启动脚本

# vim /etc/init.d/nginx

#!/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

更改权限加入系统服务并开机启动，启动服务

# chmod 755 !$

# chkconfig --add nginx

# chkconfig nginx on

# service nginx start

# service nginx restart

2、编写自定义的nginx配置文件

清空原来的配置文件

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

# vim /usr/local/nginx/conf/nginx.conf

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;

include vhosts/*.conf;    ##（将虚拟主机的位置指向了/usr/local/nginx/conf/vhosts/*.conf 这个位置，没有指向的话需要在此配置文件中定义虚拟主机）

}
