1. Tomcat相关参数修改
修改../conf/server.xml
<Connector executor="tomcatThreadPool"
port="8080" protocol="HTTP/1.1"
maxThreads="1500"
keepAliveTimeout="60000"
maxKeepAliveRequests="300"
minSpareThreads="300"
maxSpareThreads="1000"
acceptCount="200"
maxConnections="2000"
connectionTimeout="20000"
redirectPort="8443" />
增加初始化内存（初始2048M，最大3000M，以16G内存为例）：
vi bin/catalina.sh
JAVA_OPTS="-Xms2048m -Xmx3000m -XX:PermSize=512m -XX:MaxPermSize=512m"
1. Nginx 参数优化
修改配置文件nginx.conf
user www www;
worker_processes 8;
error_log logs/error.log info;
pid logs/nginx.pid;
worker_rlimit_nofile 65536;
events {
use epoll;
worker_connections 65536;
}
http {
include mime.types;
default_type application/octet-stream;
proxy_buffer_size 256k;
proxy_buffers 32 64k;
proxy_busy_buffers_size 256k;
fastcgi_buffer_size 256k;
fastcgi_buffers 32 64k;
fastcgi_connect_timeout 300;
fastcgi_read_timeout 300;
fastcgi_send_timeout 300;
proxy_connect_timeout 300;
proxy_read_timeout 300;
proxy_send_timeout 300;
server_names_hash_bucket_size 128;
sendfile on;
tcp_nopush on;
keepalive_timeout 65;
tcp_nodelay on;
gzip on;
client_max_body_size 40m;
fastcgi_intercept_errors on;
对于后台访问配置，由于柜员一般一直在线，因此我们建议采用长链接方式，这可以用来减少TCP链接数。长链接配置参数参考下述红色字体部分：
upstream khgl.httest.com
{
server 10.10.10.157:38883;
keepalive 128;
}
location / {
#proxy_pass http://192.168.0.1:38886;
proxy_pass http://xykhgl.httest.com;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-real-uri $request;
proxy_read_timeout 300s;
proxy_http_version 1.1;
proxy_set_header Connection "";
autoindex on;
}
}
