一、安装MYSQL,二、安装PHP,三、安装nginx,四、测试是否解析php文件

一、安装MYSQL


1.下载MYSQL: cd /usr/local/user

wget http://www.lishiming.net/data/at ... -icc-glibc23.tar.gz


2.解压: tar zxvf mysql-5.1.40-linux-i686-icc-glibc23.tar.gz


3.把解压后的mysql包移动到/usr/local/mysql

mv mysql-5.1.40-linux-i686-icc-glibc23.tar.gz /usr/local/mysql


4.创建mysql账户

useradd -s /sbin/nologin mysql //-s /sbin/nologin 表示mysql账号不能登陆linux


5.创建mysql的数据库存放路径并初始化数据库

cd /usr/local/mysql

mkdir -p /data/mysql

chown -R mysql:mysql /data/mysql

./scripts/mysql_install_db --user=mysql --datadir=/data/mysql //--user定义所属主,datadir 为数据库存放路径;这一步若出现两个OK就说明进行正确。


6.复制配置文件

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


7.复制启动脚本到/etc/init.d目录下,并修改权限

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

chmod 755 /etc/initd/mysqld


8.修改启动脚本

vim /etc/init.d/mysqld 找到“datadir=”改过 datadir=/data/mysql


9.把mysql添加到开机启动

chkconfig -add mysqld

chkconfig mysqld on

service mysqld start //如果启动不了,请到 /data/mysql/ 下查看错误日志,这个日志通常是主机名.err. 检查mysql是否启动的命令为: ps aux |grep mysqld


二、安装PHP


1.下载PHP

cd /usr/local/src

wget http://am1.php.net/distributions/php-5.3.27.tar.gz


2.解压

tar zxvf php-5.3.27.tar.gz


3.配置编译参数

cd /php-5.3.27.tar.gz

./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

--enable-zend-multibyte

--disable-ipv6

--with-pear

--with-curl

--with-openssl

配置参数前,最好把这些包都安装上: yum install -y gcc gcc-c++ libxml2 libxml2-devel openssl-devel libcurl-devel openjpeg openjpeg-devel gd gd-devel libmcrypt-devel 其中libmcrypt-devel需要安装扩展源后才能用yum安装(扩展源下载地址http://www.lishiming.net/data/at ... ease-6-7.noarch.rpm


4.编译

make(在这一步若出现 “/usr/bin/ld: cannot find -lltdl

collect2: ld returned 1 exit status make: *** [sapi/fpm/php-fpm] 错误 1”解决的办法是

yum install -y libtool-ltdl-devel)


5.安装

make install


6.修改配置文件

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

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

把下面的内容写入此文件内:

[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

保存配置文件后,检验配置文件是否正确:

/usr/local/php/sbin/php-fpm -t

若出现有 "test is successful" 的字段,则说明配置正确。


7.启动php-fpm

useradd -s /sbin/nologin php-fpm

cp /usr/local/src/php-5.3.27/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm

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

chkconfig php-fpm on //开机启动php-fpm服务,如果不想开机启动,此步可省略

service php-fpm start //启动php-fpm

ps aux |grep php-ftm //看看是否有开启,一共有20多个进程


三、安装nginx


1.下载nginx

cd /usr/local/src

wget

http://nginx.org/download/nginx-1.4.4.tar.gz


2.解压

tar zxvf nginx-1.4.4.tar.gz


3.配置编译参数

cd nginx-1.4.4

./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

这一步如果报错出现 “PCRE”则 yum install yum install -y pcre pcre-devel即可


4.编译和安装

make && make install

因为nginx不是很大,所以安装的很快,用“echo $?”检测上一步有没有出错,若为“0”则安装正确


5.编写nginx启动脚本并加入系统服务

vim /etc/init.d/nginx

写入如下内容:

#!/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


保存后,更改权限:

chmod 755 /etc/init.d/nginx

chkconfig --add nginx

chkconfig nginx on //些操作为开机启动nginx,若是不想可忽略;


6.更改配置文件

> /usr/local/nginx/conf/nginx.conf //">"符号为重定向,单独用它可以把一个文本文档快速的清空;

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


写入如下内容:

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;

}

}

}

保存配置后,先检验配置文件是否有错误存在:


/usr/local/nginx/sbin/nginx -t //若显示有"syntax is ok"和"test is successful"的字段则说明配置文件没有问题,否则需要根据错误提示来修改配置文件;


启动 nginx:

service nginx start

ps aux |grep nginx //查看是否有nginx的进程,是否启动;


四、测试是否解析php文件

创建测试文件:

vim /usr/local/nginx/html/1/php

写入如下内容:

echo "是否解析php"

?>php


保存后,测试:


curl localhost/1.php


是否解析php[root@username nginx-1.4.4]# //只有显示这种形式才说明正确解析,否则需要修改配置文件;


至此LNMP的环境算是搭建完成了!
