Nginx server nginxconf configuration file description

: This article describes the Nginx server nginxconf configuration file. if you are interested in the PHP Tutorial, refer to it. Record the description of the Nginx. conf configuration file on the nginx server, partial annotation collection and network.

Running user

User www-data;

Start the process, usually set to equal to the number of CPUs

Worker_processes 1;

Global error logs and PID files

Error_log/var/log/nginx/error. log;
Pid/var/run/nginx. pid;

Working mode and maximum number of connections

Events {
Use epoll; # epoll is a method of Multiplexing IO (I/O Multiplexing), but it is only used for Linux and later kernels, which can greatly improve nginx performance.
Worker_connections 1024; # maximum number of concurrent connections of a single backend worker process
# Multi_accept on;
}

Sets the http server and uses its reverse proxy function to provide load balancing support

# The sendfile command specifies whether nginx calls the sendfile function (zero copy mode) to output files. for common applications, # it must be set to on. if it is used for downloading and other application disk I/O heavy load applications, it can be set to off to balance the disk and network I/O processing speed and reduce the system uptime. sendfile on; # tcp_nopush on; # connection timeout # keepalive_timeout 0; keepalive_timeout 65; tcp_nodelay on; # enable gzip compression gzip on; gzip_disable "MSIE [1-6] \.

Server {

}

The above are some basic configurations. The biggest advantage of using Nginx is load balancing.

To use server load balancer, you can modify and configure the http node as follows:

Sets the http server and uses its reverse proxy function to provide load balancing support

Http {
# Set the mime type, which is defined by the mime. type file.
Include/etc/nginx/mime. types;
Default_type application/octet-stream;
# Set the log format
Access_log/var/log/nginx/access. log;

# Omit some of the above configuration nodes #.......... # Set the upstream mysvr {# The weigth parameter in the server list of server load balancer to indicate the weight. the higher the weight, the higher the probability of being allocated to the server 192.168.8.1x: 3128 weight = 5; # enable port 3128 of server 192.168.8.2x: 80 weight = 1; server 192.168.8.3x: 80 weight = 6 ;}

Upstream mysvr2 {
# The weigth parameter indicates the weight. a higher weight indicates a higher probability of being assigned.

server 192.168.8.x:80  weight=1;server 192.168.8.x:80  weight=6;}

# First Virtual Server
Server {
# Listen to port 80 of 192.168.8.x
Listen 80;
Server_name 192.168.8.x;

# Load balancing request location ~ for aspx suffix ~ . *\.
