php-fpm由TCP端口通信改为Unit socket通信

标签:port 情况 直接 cycle client 而且 php 大数据 min 原理上来说,unix socket方式肯定要比tcp的方式快而且消耗资源少,因为socket之间在nginx和php-fpm的进程之间通信,而tcp需要经过本地回环驱动,还要申请临时端口和tcp相关资源,unix socket会显得不是那么稳定,当并发连接数爆发时,会产生大量的长时缓存,在没有面向连接协议支撑的情况下,大数据包很有可能就直接出错并不会返回异常。而TCP这样的面向连接的协议,多少可以保证通信的正确性和完整性。 修改www.conf 修改nginx配置文件; 修改sysctl.conf; //上面参数是必须的,1是增加端口数量,2是减少time_wait连接过多 先restart php-fpm 进行测试 www.conf示例内容: php-fpm由TCP端口通信改为Unit socket通信 标签:port 情况 直接 cycle client 而且 php 大数据 min 原文地址:https://blog.51cto.com/liujingyu/2530179touch /var/run/php-fcgi.sock
chmod 777 /var/run/php-fcgi.sock
chown nginx. /var/run/php-fcgi.sock
listen = /var/run/php-fcgi.sock
listen.owner = nginx
listen.group = nginx
listen.mode = 0666
user = nginx
group = nginx
# fastcgi_pass 127.0.0.1:9000;
fastcgi_pass unix:/var/run/php-fcgi.sock;
# vi /etc/sysctl.conf
net.ipv4.ip_local_port_range = 1024 65535
net.ipv4.tcp_syncookies = 1
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_tw_recycle = 1
net.ipv4.tcp_fin_timeout = 30
# sysctl –p
然后:nginx -s stop
Nginx
不能用restart,会出错,解决步骤:ps -aux | grep nginx | awk ‘{print $2}’| xargs kill -9
