nginx常用配置文件
1.主配置文件
user www www;
worker_processes 2;
error_log logs/error.log;
pid logs/nginx.pid;
worker_rlimit_nofile 51200;
events {
use epoll;
worker_connections 51200;
}
http {
charset utf-8;
include mime.types;
default_type application/octet-stream;
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 60;
server_tokens off;
limit_conn_log_level error; #当达到最大限制连接数时,记录日志的等级
limit_conn_status 503; #该参数在1.3.15版本引入的。指定当超过限制时,返回的状态码(默认是503),code值只能设置在400到599之间。
limit_conn_zone $binary_remote_addr zone=one:10m;
#用于定义一个zone,该zome将会被用于存储会话状态。能够存储的会话数量是由定义的size大小和系统参数memory_max_size的大小决定的。
#zone是共享内存空间,作用是保存每个key对应的连接数,此处可以按照需求自己定义名字。
limit_conn_zone $server_name zone=perserver:10m; #
limit_req_zone $binary_remote_addr zone=allips:10m rate=10r/s;#对每个连接的速率限制。参数rate的单位是字节/秒,设置为0将关闭限速。
#按连接限速而不是按IP限制,因此如果某个客户端同时开启了两个连接,那么客户端的整体速率是这条指令设置值的2倍。
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for" "$request_time"';
access_log logs/access.log main;
gzip on;
gzip_min_length 1k;
gzip_buffers 4 16k;
gzip_http_version 1.1;
gzip_comp_level 2;
gzip_types text/plain application/x-javascript text/css application/xml;
gzip_vary on;
include vhosts/*.conf;
include upstream/*.conf;
}
2.主机配置文件
server {
listen 80;
server_name xxx.xxx.xxx;
root /data/web/myblog;
index index.html index.php;
access_log /usr/local/nginx/logs/blog/access.log main;
error_log /usr/local/nginx/logs/blog/error.log;
limit_conn one 10;
limit_conn perserver 1000;
limit_req zone=allips burst=10 nodelay;
location ~ \.php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
include fastcgi_params;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /opt/web/error_page/;
}
}
3.定制json格式的日志文件,记录客户端IP
log_format main escape=json '{"remote_addr":"$remote_addr",'
'"remote_user":"$remote_user",'
'"time_local":"$time_local",'
'"request":"$request",'
'"status":"$status",'
'"body_bytes_sent":"$body_bytes_sent",'
'"http_referer":"$http_referer",'
'"http_user_agent":"$http_user_agent",'
'"http_x_forwarded_for":"$http_x_forwarded_for"}';
access_log logs/access.log main;
