LNMP搭建

 Linux + Nginx(FastCGI) + PHP(php-fpm) + MySQL

php安装在mysql后

 [扩展]

mysql安装：略（同LAMP）

注:

1.nginx没有apache的apachectl工具，需要写一个

2.LNMP需要开启php服务

3.nginx本身不能解析php，它只是一个简单的web服务软件，但nginx有一个很好的功能就是可以作为代理服务器，而php-fpm是可以解析php的，所以只要nginx代理一下php-fpm就可以解析php啦，nginx和php是单独跑的。

4.mysql、php各需要一个用户来监听

php安装

 

5.4是企业常用版本

1.下载php到/usr/local/src/: 

wget http://cn2.php.net/get/php-5.4.45.tar.bz2/from/this/mirror

2.解压:

tar jxvf  php-5.4.45.tar.bz2

cd php-5.4.45

 安装库

yum install -y libxml2-devel;
yum install -y libjpeg libjpeg-devel;
yum install -y libpng libpng-devel;
yum install -y freetype freetype-devel;
yum install -y bzip2 bzip2-devel;
yum install -y openssl openssl-devel;
rpm -ivh "http://www.aminglinux.com/bbs/data/attachment/forum/month_1211/epel-release-6-7.noarch.rpm";
yum install -y  libmcrypt-devel
yum install -y pcre-devel

创建账号

useradd -s  /sbin/nologin php-fpm

配置编译参数

cd /usr/local/src/php-5.4.45

./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

make

make install 

修改配置文件

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

拷贝启动脚本：
cp /usr/local/src/php-5.4.45/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

编辑php-fpm.conf文件，在其中添加下面一段配置：

[www]
listen = /tmp/php-fcgi.sock  #名字可以自定义
user = php-fpm
group =php-fpm
pm = dynamic  #动态的管理下面的内容
pm.max_childre = 50 #子进程最大有50个
pm.start_servers = 20 #最开始启动20个
pm.min_spare_servers = 5 #空闲的时候最小不能低于5个
pm.max_spare_servers = 35 # 最多的时候不能多与35个子进程
pm.max_requests = 500 #一个子进程在一个生命周期内处理多少个请求然后销毁
rlimit_files = 1024 #  每个进程使用的文件描述符的限制（可调大一点）
listen.mode = 777

 

启动php-fpm
chmod 755 /etc/init.d/php-fpm 
chkconfig --add php-fpm;chkconfig php-fpm on
service php-fpm start 

检测是否启动:

ps aux |grep php-fpm

nginx安装：

 官网：nginx.org

下载nginx

cd /usr/local/src/

wget http://nginx.org/download/nginx-1.6.2.tar.gz

解压nginx

tar zxvf nginx-1.6.2.tar.gz

配置编译参数

cd nginx-1.6.2

./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

make 

make install

把/usr/local/nginx/sbin加入系统路径

启动nginx：  
nginx

停止nginx:

nginx -s stop

重载：nginx -s reload

 

编写nginx启动脚本，并加入系统服务

 这样在控制台就很容易的操作nginx了：查看Nginx当前状态、启动Nginx、停止Nginx、重启Nginx…

vim /etc/init.d/nginx

#!/bin/bash
# chkconfig: - 30 21

        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　

 chmod 755 /etc/init.d/nginx

 chkconfig --add nginx

 

 开机启动

chkconfig nginx on
