Nginx virtual host, reverse proxy instance

First, the main configuration file configuration:

#user nobody;
Worker_processes 4;

Error_log Logs/error.log debug_http;
#error_log Logs/error.log Notice;
#error_log Logs/error.log Info;

#pid Logs/nginx.pid;


Events {
Use Epoll; One way in #epoll是多路复用IO (I/O multiplexing),
Worker_connections 1024; Maximum number of concurrent links #单个后台worker process processes

# Concurrent totals are the product of worker_processes and Worker_connections
# that is max_clients = worker_processes * worker_connections
# in the case of a reverse proxy set, max_clients = worker_processes * WORKER_CONNECTIONS/4 why
# Why the reverse proxy above is divided by 4, should be said to be an empirical value
# Depending on the above conditions, the maximum number of connections that the Nginx server can cope with normally is: 4 * 8000 = 32000
# The setting of the Worker_connections value is related to the physical memory size
# Because of concurrent IO constraints, the value of max_clients must be less than the maximum number of files that the system can open
# while the maximum number of files that the system can open is proportional to the size of the memory, the number of files that can be opened on a 1GB memory machine is about 100,000 or so.
# Let's take a look at the number of file handles that the VPS of 360M memory can open:
# $ Cat/proc/sys/fs/file-max
# Output 34336
# 32000 < 34336, that is, the total number of concurrent connections is less than the total number of file handles that the system can open, which is within the operating system's reach
# Therefore, the value of worker_connections should be set appropriately based on the number of worker_processes processes and the maximum number of files that the system can open
# makes the number of concurrent totals less than the maximum number of files that the operating system can open
# Its essence is configured based on the host's physical CPU and memory
# Of course, the total number of concurrent sums in theory can be somewhat skewed, as the host has other worker processes that consume system resources.
# Ulimit-shn 65535

HTTP {
Include Mime.types;#设定mime类型, the type is defined by the Mime.type file

include/usr/local/nginx/conf/conf.d/*.conf; #包含其他文件
Default_type Application/octet-stream;

Sendfile on;

#sendfile instruction Specifies whether Nginx calls the Sendfile function (zero copy mode) to output the file,
#对于普通应用, must be set to ON,
#如果用来进行下载等应用磁盘IO重负载应用, can be set to OFF,
#以平衡磁盘与网络I/O processing speed, reducing the uptime of the system.

#tcp_nopush on;

Tcp_nodelay on;

server {
Listen 80;
server_name localhost;
Access_log Logs/access.log;
Error_log Logs/error.log;
CharSet Utf-8;

Location/{
Index index.html index.htm;
root HTML;
}

Error_page 502 503 504/50x.html;
Location =/50x.html {
root HTML;
}
}
}

Second, the virtual host:

Add vhosts.conf under the CONF.D directory

server {
Listen 172.16.171.101:80;
server_name www.wushank.com;
CharSet Utf-8;
Error_log Logs/wushank/error.log;
Access_log Logs/wushank/access.log;
Location/{
Root/var/www/html/wushank;
Index index.html index.htm;
}
}
server {
Listen 172.16.171.101:80;
server_name www.test.com;
CharSet Utf-8;
Error_log Logs/test/error.log;
Access_log Logs/test/access.log;

Location/{
Root/var/www/html/test;
Index index.html index.htm;
}
}
server {
Listen 10.1.1.100:8000;
server_name localhost;
CharSet Utf-8;
Error_log Logs/wang/error.log;
Access_log Logs/wang/access.log;

Location/{
Root/wang;
Index index.html index.htm;
}
}

Third, reverse proxy configuration:

Upstream F5-test {
Server 172.16.171.100:8080;
Server 172.16.171.110:80;
Server 172.16.171.120:80;
}

server {
Listen 80;
server_name 172.16.171.100 f5.sky.com;

Location ~ \.php$ {
root/var/www/html;
Fastcgi_pass 127.0.0.1:9000;
Fastcgi_index index.php;
Fastcgi_param script_filename $document _root$fastcgi_script_name;
Include Fastcgi_params;
}

#设置反向代理的全局信息

Proxy_set_header X-real-ip $remote _addr;
Proxy_set_header x-forwarded-for $proxy _add_x_forwarded_for;
Client_max_body_size 50m;
Client_body_buffer_size 256k;
Proxy_connect_timeout 30;

Proxy_buffer_size 16k;
Proxy_buffers 4 32k;
Proxy_busy_buffers_size 64k;

#根据URI对不同的目录进行反向代理

location/f5/{

Error_log Logs/f5/error.log;
Proxy_pass http://f5-test/f5/;
Proxy_redirect default;
}
location/wushank/{

}
}
