nginx添加如下配置然后reload一下就好了：
worker_rlimit_nofile 655350;
worker_connections 60000; # 需要小于或等于 worker_rlimit_nofile
2019/12/14 20:24:12 [alert] 2642#2642: setrlimit(RLIMIT_NOFILE, 65535) failed (1: Operation not permitted)
setsebool -P httpd_setrlimit 1
kernel: TCP: request_sock_TCP: Possible SYN flooding on port 9000. Sending cookies. Check SNMP counters.[alert] 1319#1319: 1024 worker_connections are not enough
nginx配置代理转发，部分配置如下
location / {
# index index.html index.htm index.php;
# try_files $uri $uri/ /index.php$request_uri;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Real-Port $remote_port;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass https://10.29.185.61:8063;
}
$proxy_add_x_forwarded_forthe “X-Forwarded-For” client request header field with the $remote_addr variable appended to it, separated by a comma. If the “X-Forwarded-For” field is not present in the client request header, the $proxy_add_x_forwarded_for variable is equal to the $remote_addr variable.
“ X-Forward-For”客户端请求头字段，后面附加 $remote _ addr 变量，中间用逗号分隔。如果客户端请求头中没有“ X-Forward-For”字段，则 $proxy_add_x_forwarded_for 变量等于 $remote_addr 变量。
To set up the yum repository, create the file named /etc/yum.repos.d/nginx.repo with the following contents:
[nginx-stable] name=nginx stable repo baseurl=http://nginx.org/packages/centos/$releasever/$basearch/ gpgcheck=1 enabled=1 gpgkey=https://nginx.org/keys/nginx_signing.key
http://nginx.org/en/docs/http/ngx_http_core_module.html#client_max_body_size
| Syntax: | client_max_body_size size; |
|---|---|
| Default: |
client_max_body_size 1m;
|
| Context: | http, server, location |
这次不能忘记了啊
