Starting php_fpm eAccelerator: Could not allocate

注：今天64位机器碰到同样情况，转之 启动PHP错误信息如下： 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 /p

注：今天64位机器碰到同样情况，转之

启动PHP错误信息如下：

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

解决办法如下：

/etc/sysctl.conf 新增：
kernel.shmmax = 128000000

sysctl -p

#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）
