php 启动报错如何解决

复制代码 代码如下:

[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.
[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

复制代码 代码如下:

[root@abc lnmp]# vi /etc/sysctl.conf
# kernel sysctl configuration file for red hat linux
#
# for binary values, 0 is disabled, 1 is enabled. see sysctl(8) and
# sysctl.conf(5) for more details.
# controls ip packet forwarding
net.ipv4.ip_forward = 0
# controls source route verification
net.ipv4.conf.default.rp_filter = 1
# do not accept source routing
net.ipv4.conf.default.accept_source_route = 0
# controls the system request debugging functionality of the kernel
kernel.sysrq = 0
# controls whether core dumps will append the pid to the core filename.
# useful for debugging multi-threaded applications.
kernel.core_uses_pid = 1
# controls the use of tcp syncookies
net.ipv4.tcp_syncookies = 1
# disable netfilter on bridges.
net.bridge.bridge-nf-call-ip6tables = 0
net.bridge.bridge-nf-call-iptables = 0
net.bridge.bridge-nf-call-arptables = 0
fs.file-max=65535
net.ipv4.tcp_max_syn_backlog = 65536
net.core.netdev_max_backlog = 32768
net.core.somaxconn = 32768
net.core.wmem_default = 8388608
net.core.rmem_default = 8388608
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216
net.ipv4.tcp_timestamps = 0
net.ipv4.tcp_synack_retries = 2
net.ipv4.tcp_syn_retries = 2
net.ipv4.tcp_tw_recycle = 1
#net.ipv4.tcp_tw_len = 1
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_mem = 94500000 915000000 927000000
net.ipv4.tcp_max_orphans = 3276800
# time_out后等待时间
#net.ipv4.tcp_fin_timeout = 30
#net.ipv4.tcp_keepalive_time = 120
net.ipv4.ip_local_port_range = 1024 65535
kernel.shmmax = 128000000

加上最后一句话 kernel.shmmax = 128000000
然后应用sysctl -p
复制代码 代码如下:

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