Nginx - installation configuration + clear cache module installation

Please indicate the source for reprinting: https://blog.csdn.net/l1028386804/article/details/80077664

1. Environment

Operating System: CentOS, RedHat
IP Address: 192.168.209.121

2. Download the software package

yum install -y gcc gcc-c++ autoconf wget
yum -y install wget gcc-c++ ncurses ncurses-devel cmake make perl bison openssl openssl-devel gcc* libxml2 libxml2-devel curl-devel libjpeg* libpng* freetype*
yum install pcre*
yum install openssl*

cd /usr/local/src
Nginx:
wget http://www.nginx.org/download/nginx-1.9.3.tar.gz
Nginx cache purge module (optional):
wget http://labs.frickle.com/files/ngx_cache_purge-2.3.tar.gz

3. Edit and install

tar -zxvf nginx-1.9.3.tar.gz
tar -zxvf ngx_cache_purge-2.3.tar.gz
cd nginx-1.9.3
./configure  --prefix=/usr/local/nginx-1.9.3 --with-http_stub_status_module --with-http_ssl_module --with-http_realip_module --add-module=/usr/local/src/ngx_cache_purge-2.3
make
make install

4. Kernel parameter optimization

# vim /etc/sysctl.conf Add the following configuration
net.ipv4.netfilter.ip_conntrack_tcp_timeout_established = 1800
net.ipv4.ip_conntrack_max = 16777216 # If the default parameters are used, network packet loss is prone to occur
net.ipv4.netfilter.ip_conntrack_max = 16777216 # If the default parameters are used, network packet loss is prone to occur
net.ipv4.tcp_max_syn_backlog = 65536
net.core.netdev_max_backlog = 32768
net.core.somaxconn = 32768
net.core.wmem_default = 8388608
net.core.rmem_default = 8388608
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216
net.ipv4.tcp_timestamps = 0
net.ipv4.tcp_synack_retries = 2
net.ipv4.tcp_syn_retries =
net.ipv4.tcp_tw_recycle = 1
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_mem = 94500000 915000000 927000000
net.ipv4.tcp_max_orphans = 3276800
net.ipv4.ip_local_port_range = 1024 65535

Configuration takes effect

# sysctl –p

Modify the iptables startup script and add it to the star() function

# vim /etc/init.d/iptables
/sbin/sysctl -p

6. Modify the nginx configuration file

vim nginx.conf

user nobody nobody; # The group and owner of running nginx
worker_processes 2; # Start two nginx worker processes, generally write a few CPU cores
error_log logs/error.log notice; # error log path
pid logs/nginx.pid; # pid 路径
events {
	worker_connections 1024; # A process can handle 1024 requests at the same time
}
http {
	include mime.types;
	default_type application/octet-stream;
	log_format main '$remote_addr – $remote_user [$time_local] "$request"'
	'$status $body_bytes_sent "$http_referer" '
	'"$http_user_agent" "$http_x_forwarded_for"';
	access_log logs/access.log main; # Default access log path
	sendfile on;
	keepalive_timeout 65; # keepalive timeout
	# Start to configure a domain name, a server configuration section generally corresponds to a domain name
	server {
		listen 80; #
		# Monitor 80 on all ips of this machine, or it can be written as 192.168.209.121:80, in this case, only monitor port 80 on 192.168.209.121
		server_name www.heytool.com; # domain name
		root /www/html/www.heytool.com; # Site root directory (program directory)
		index index.html index.htm; # index file
		location / { # can have multiple locations
			root /www/html/www.heytool.com; # Site root directory (program directory)
		}
		error_page 500 502 503 504 /50x.html;
		# Define the error page, if it is a 500 error, return 50x.html in the root directory of the site to the user
		location = /50x.html {
			root /www/html/www.heytool.com;
		}
	}
	#Start configuring the site bbs.heytool.com
	server {
		listen 80;
		server_name bbs.heytool.com;
		root /www/html/bbs.heytool.com;
		index index.html index.htm; # index file
		location / {
			root /www/html/bbs.heytool.com;
		}
		error_page 500 502 503 504 /50x.html;
		location = /50x.html {
			root /www/html/bbs.heytool.com;
		}
	}
}

7. Nginx startup and shutdown

# /usr/local/nginx-1.9.3/sbin/nginx //Start nginx
# /usr/local/nginx-1.9.3/sbin/nginx –t //Test the accuracy of the nginx configuration file
# /usr/local/nginx-1.9.3/sbin/nginx –s reload //Reload nginx
# /usr/local/nginx-1.9.3/sbin/nginx –s stop //Close nginx

8. Test

Create a test site

# mkdir -p /www/html/www.heytool.com
# mkdir -p /www/html/bbs.heytool.com
# echo "www.heytool.com" > /www/html/www.heytool.com/index.html
# echo "bbs.heytool.com" > /www/html/bbs.heytool.com/index.html

9. Bind hosts and test

Point the two domain names to 192.168.209.121

192.168.209.121 www.heytool.com
192.168.209.121 bbs.heytool.com
