nginx访问http自动跳转https

#这个指令是指当一个nginx 进程打开的最多文件描述符数目，理论值应该是最多打开文件数（ulimit -n）与nginx 进程数相除，但是nginx 分配请求并不是那么均匀，所以最好与ulimit -n 的值保持一致
#如果nginx 中worker_connections 值设置是1024，worker_processes 值设置是4，按反向代理模式下最大连接数的理论计算公式：
#最大连接数 = worker_processes * worker_connections / 4
#生产环境中worker_connections 建议值最好超过9000，计划将一台nginx 设置为10240，再观察一段时间
worker_rlimit_nofile 65535;
events {
    #默认最大的并发数为1024，如果你的网站访问量过大，已经远远超过1024这个并发数，那你就要修改worker_connecions这个值 ，这个值越大，并发数也有就大
