2015-05-11LNMP第一部分环境搭建

1. MySQL安装（同LAMP里面的安装方法）
2.  php安装
wget  http://cn2.php.net/distributions/php-5.4.37.tar.bz2
tar jxf php-5.4.37.tar.bz2
useradd -s /sbin/nologin php-fpm 
cd php-5.4.37
./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-curl

yum install   -y  libxml2*   libcurl*  mcrypt*  libmcrypt*  gcc

make && make install

make   test
Wrote PEAR system config file at: /usr/local/php/etc/pear.conf

You may want to add: /usr/local/php/lib/php to your php.ini include_path

/usr/local/mysql/php-5.4.37/build/shtool install -c ext/phar/phar.phar /usr/local/php/bin

ln -s -f /usr/local/php/bin/phar.phar /usr/local/php/bin/phar

Installing PDO headers:          /usr/local/php/include/php/ext/pdo/
cp php.ini-production /usr/local/php/etc/php.ini 
拷贝启动脚本：
cp /usr/local/src/php-5.4.37/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm 
mv /usr/local/php/etc/php-fpm.conf.default  /usr/local/php/etc/php-fpm.conf
chmod 755 /etc/init.d/php-fpm 
chkconfig --add php-fpm
service php-fpm start 
chkconfig php-fpm on 
3. 安装nginx
cd /usr/local/src/
wget http://nginx.org/download/nginx-1.6.2.tar.gz
tar zxvf nginx-1.6.2.tar.gz 
cd nginx-1.6.2
./configure   --prefix=/usr/local/nginx   --with-pcre

yum install  -y  pcre*  zlib*   
make 
make install
启动nginx：  
/usr/local/nginx/sbin/nginx
4. 编写nginx启动脚本
vim /etc/init.d/nginx  //加入如下内容
#!/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，执行
chmod a+x /etc/init.d/nginx
chkconfig --add nginx
chkconfig nginx on
5. 配置解析php
vim  /usr/local/nginx/conf/nginx.conf   //把下面的配置，前面的#删除，并更改fastcgi_param SCRIPT_FILENAME 那一行

1.         location ~ \.php$ {
2.             root           html;
3.             fastcgi_pass   127.0.0.1:9000;
4.             fastcgi_index  index.php;
5.             fastcgi_param  SCRIPT_FILENAME  /usr/local/nginx/html$fastcgi_script_name;
6.             include        fastcgi_params;
7.         }

复制代码

重新加载 /usr/local/nginx/sbin/nginx -s  reload
vim  /usr/local/nginx/html/1.php 
增加  
<?php
    phpinfo();
?>
测试： curl localhost/1.php 
[root@centos-03 nginx]# find  /  -name  error.log
/usr/local/nginx/logs/error.log
less  /usr/local/php/var/log/php-fpm.log
