php 启动报错如何解决

[root@abc lnmp]# service php-fpm start 
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.

加上最后一句话 kernel.shmmax = 128000000
然后应用sysctl -p
