PHP与nginx及linux的性能设置.

##PHP配置##

php-fpm设置:

一./etc/php/5.5/fpm/pool.d/www.conf中

pm.max_children = 200

pm.start_servers = 9

pm.min_spare_servers = 9

pm.max_spare_servers = 150

listen.backlog = 4096

PHP.ini配置:

二./etc/php/5.5/fpm/php.ini

memory_limit= 10240M

php opcache设置:

三./etc/php/5.5/fpm/conf.d/10-opcache.ini:

opcache.enable=1

opcache.enable_cli  1

opcache.fast_shutdown  1

opcache.file_update_protection   0

opcache.max_accelerated_files  100000

opcache.memory_consumption  5120

opcache.revalidate_freq  10

##nginx配置##

/etc/nginx/nginx.conf

worker_processes auto;

worker_rlimit_nofile 200000;

events {

worker_connections 10240;

#multi_accept on;

}

access_log off;

##linux 内核参数##

编辑文件vi /etc/sysctl.conf，加入以下内容：解决大量TIME_WAIT

net.ipv4.tcp_syncookies = 1

net.ipv4.tcp_tw_reuse = 1

net.ipv4.tcp_tw_recycle = 1

net.ipv4.tcp_fin_timeout = 30

解决高并发的时候PHP-fpm出现一些错误  connect() to unix:/var/run/php-fpm.sock failed (11: Resource temporarily unavailable) :

net.ipv4.tcp_max_syn_backlog = 4096

net.core.netdev_max_backlog = 4096

然后执行 sysctl -p 让参数生效。

/etc/security/limits.conf:

* soft nofile 1048576

* hard nofile 1048576

root soft nofile 1048576

root hard nofile 1048576

然后重启服务器

临时修改的话ulimit -n 1048576就可以了,不用重启服务器

查看是否生效

ulimit -a
