查看php-fpm慢日志

目前出现的问题基本上都是too many open file的错误,

优化建议：

1，代码层面，减少api项目内部curl调用(继续优化ichuntapi项目内部的curl调用)

2，迁移项目到其它服务器（增加php-fpm资源）
user.ichunt.net
perm.ichunt.net
so.ichunt.com

2.1优化php-fpm参数调优

2.2根据php-fpm慢日志（上面的请求慢日志）优化代码

3，增加内存，服务器内存已不足

4,linux性能调优

查看当前TCP连接的状态和对应的连接数量：
[huntadmin@iZwz9diw9y2w5pkse0cx3jZ wwwroot]$ netstat -n | awk '/^tcp/ {++S[$NF]} END {for(a in S) print a, S[a]}'
TIME_WAIT 3397
CLOSE_WAIT 214
FIN_WAIT1 9
FIN_WAIT2 2

vim /etc/sysctl.conf

net.ipv4.tcp_syncookies= 1 #开启SYNCookies。当SYN等待队列溢出时，启用cookies处理，可防范少量SYN攻击，默认0，表关闭；
net.ipv4.tcp_tw_reuse= 1 #开启重用。允许将TIME-WAITsockets重用于新的TCP连接，默认0，表示关闭；
net.ipv4.tcp_tw_recycle= 1 #开启TCP连接中TIME-WAITsockets的快速回收，默认0，表关闭；
net.ipv4.tcp_fin_timeout= 30 #修改系統默认的 TIMEOUT 时间。

#输入下面的命令，让内核参数生效：
