復制代碼 代碼如下:
[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
復制代碼 代碼如下:
[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后等待時間
#NET.ipv4.tcp_fin_timeout = 30
#NET.ipv4.tcp_keepalive_time = 120
NET.ipv4.ip_local_port_range = 1024 65535
kernel.shmmax = 128000000
加上最后一句話 kernel.shmmax = 128000000
然后應用sysctl -p
復制代碼 代碼如下:
[root@abc lnmp]# service php-fpm start
Starting php-fpm done
[root@abc lnmp]# /usr/bin/memcachedstart
