Php startup error

Php startup reports an error. many of my friends may have encountered this problem. The following is a specific solution. The code is as follows:

[Root @ abc lnmp] # service php-fpm start
Starting php-fpm eAccelerator: cocould 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.
[04-Dec-2013 19:06:44] NOTICE: PHP message: PHP Warning: [eAccelerator] Can not create shared memory area in Unknown on line 0
[04-Dec-2013 19:06:44] NOTICE: PHP message: PHP Fatal error: Unable to start eAccelerator module in Unknown on line 0
Failed

The code is as follows:

[Root @ abc lnmp] # vi/etc/sysctl. conf

Kernel. shmmax = 128000000

Add the last statement kernel. shmmax = 128000000
Then apply sysctl-p

The code is as follows:

[Root @ abc lnmp] # service php-fpm start
Starting php-fpm done
[Root @ abc lnmp] #/usr/bin/memcachedstart
