FastDFS性能优化

1.linux系统优化

#linux优化
#查看性能
ulimit -a
#修改打开文件数量
vi /etc/security/limits.conf

#配置详情

* soft nofile 65536
* hard nofile 68836
* soft nproc 4096
* hard nproc 4096

2.nginx优化（集群每台都要优化）

#user  nobody;
#根据CPU的数量配置
worker_processes  4;

worker_rlimit_nofile 65535;
events {
    worker_connections  20480;
}

http {
    include       mime.types;
    default_type  application/octet-stream;
    #开启高效文件传输模式
    sendfile on;
    #减少网络报文段数量
    #tcp_nopush on;
    #提高I/O性能
    tcp_nodelay on;

    #keepalive_timeout  0;
    keepalive_timeout  65;
    #tracker节点负载均衡配置
    upstream fastdfs_tracker {
       server 172.16.1.83:8000 weight=1 max_fails=2 fail_timeout=30s;
       server 172.16.1.74:8000 weight=1 max_fails=2 fail_timeout=30s;
    }

    server {
        listen       80;
        server_name  localhost;

        location / {
            root   html;
            index  index.html index.htm;
        }

       
        error_page   500 502 503
