#=======================在不停止Nginx服务的情况下平滑变更Nginx配置======================================
 1、修改/usr/local/nginx/conf/nginx.conf配置文件后，请执行以下命令检查配置文件是否正确：
/usr/local/nginx/sbin/nginx -t
/*
 如果屏幕显示以下两行信息，说明配置文件正确：
 　　the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
 　　the configuration file /usr/local/nginx/conf/nginx.conf was tested successfully
 */
 2、平滑重启：
 ①、对于Nginx 0.8.x版本，现在平滑重启Nginx配置非常简单，执行以下命令即可：
/usr/local/nginx/sbin/nginx -s reload

②、对于Nginx 0.8.x之前的版本，平滑重启稍微麻烦一些，按照以下步骤进行即可。输入以下命令查看Nginx主进程号：
ps -ef | grep "nginx: master process" | grep -v "grep" | awk -F ' ' '{print $2}'
屏幕显示的即为Nginx主进程号，例如：
 　　6302
 这时，执行以下命令即可使修改过的Nginx配置文件生效：
kill -HUP 6302
#或者无需这么麻烦，找到Nginx的Pid文件：
 kill -HUP `cat /usr/local/nginx/nginx.pid`

#===========================编写每天定时切割Nginx日志的脚本==============================================

 Starting php_fpm eAccelerator: Could not allocate 67108864 bytes, the maximum size the kernel allows is 33554432 bytes. Lower the amount of memory request or increase the limit in /proc/sys/kernel/shmmax.
 PHP Warning:  [eAccelerator] Can not create shared memory area in Unknown on line 0
 PHP Fatal error:  Unable to start eAccelerator module in Unknown on line 0
  failed
 
 #说明

php.ini中设置的eAccelerator，eaccelerator.shm_size="64"，解释：eaccelerator可使用的共享内存大小(单位为MB)，即64M
 在Linux下，单个进程的最大内存使用量受/proc/sys/kernel/shmmax中设置的数字限制(单位为字节)  /proc/sys/kernel/shmmax = 33554432 （32M）
 临时更改该值：
 echo 128000000 > /proc/sys/kernel/shmmax
 或者
 vi /etc/sysctl.conf
 kernel.shmmax = 128000000
