This article mainly introduces the relevant knowledge of "how to use the server's Load Balancer nginx+tomcat to realize static separation." The editor shows you the operation process through actual cases. The operation method is simple, fast and practical. I hope this article "how to use the server's Load Balancer nginx+tomcat to realize static separation" can help you solve the problem.

Case study: tomcat server deployment
Prepare jdk and tomcat on two tomcat servers
jdk download
tomcat download
mkdir /toolscd /toolslsapache-tomcat-8.5.70.tar.gz jdk-8u181-linux-x64.tar.gz
install the JDK
mkdir -p /app/javatar xf jdk-8u181-linux-x64.tar.gz -C /app/ln -s /app/jdk1.8.0_181/ /app/jdkvim /etc/profileexport JAVA_HOME=/app/jdkexport CLASSPATH=.:$ JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jarexport PATH=$PATH:$JAVA_HOME/binsource /etc/profilejava -versionjava version "1.8.0_181"Java(TM) SE Runtime Environment (build 1.8.0_181-b13)Java HotSpot(TM) 64-Bit Server VM (build 25.181-b13, mixed mode)
Deploying tomcat
tar xf apache-tomcat-8.5.70.tar.gz -C /appln -s /app/apache-tomcat-8.5.70/ /app/tomcat
Start tomcat and test, tomcat default start port 8080
/app/tomcat/bin/startup.shss -anpt | grep 8080LISTEN 0 100 [::]:8080 [::]:* users:(("java",pid=2375,fd=52))
See the above page to indicate successful deployment
Create tomcat01 Site Home
rm -rf /app/tomcat/webapps/ROOT/*cat /app/tomcat/webapps/ROOT/index.jsp tomcat01
Create womcat02 Site Home
rm -rf /app/tomcat/webapps/ROOT/*cat /app/tomcat/webapps/ROOT/index.jsp tomcat02
Two tomcat servers restart service
The requested URL/app/tomcat/bin/shutdown.sh was not found on this server.
Install nginx dependencies
yum -y install gcc gcc-c++ autoconf pcre-devel make automake httpd-tools enopssl-devel
Configure nginx software sources
cat /etc/yum.repos.d/nginx.repo [nginx-stable]name=nginx stable repobaseurl=http://nginx.org/packages/centos/$releasever/$basearch/gpgcheck=1enabled=1gpgkey=https://nginx.org/keys/nginx_signing.keymodule_hotfixes=true
Install nginx service and start
yum clean allyum makecacheyum -y install nginxsystemctl enable --now nginx
yum installed nginx has profile separation enabled, we use the default profile
cat /etc/nginx/nginx.confinclude /etc/nginx/conf.d/*.conf;#Modify default configuration file vim /etc/nginx/conf.d/default.confserver { listen 80; server_name 192.168.10.3;
Create a new website
The requested URL/html/index.html was not found on this server. body { width: 35em; margin: 0 auto; font-family: Tahoma, Verdana, Arial, sans-serif; }
Restart nginx service
systemctl reload nginx
Ah, pictures.
Deploying nginx-lb servers
The installation steps are the same as the first three steps of nginx01
Create a Load Balancer Profile
vim /etc/nginx/conf.d/proxy.confupstream tomcat { server 192.168.10.4:8080; server 192.168.10.5:8080;}upstream static { server 192.168.10.3:80;}server { listen 80; server_name 192.168.10.2; location / { proxy_pass http://tomcat; } location ~* .*\. (png|gif|jpg)$ { proxy_pass http://static; }}
Restart nginx service
nginx -tnginx: the configuration file /etc/nginx/nginx.conf syntax is oknginx: configuration file /etc/nginx/nginx.conf test is successfulsystemctl reload nginx
The principle is that tomcat backend server will be accessed by default, but static backend will be accessed when there are static images in the web page.
