Installation and configuration method of Nginx+tomcatLVS cluster

LVS cluster nginx+tomcat

Project topology map:

1. Install nginx +
tomcat

The configurations on the 192.168.1.248 and 192.168.1.249 servers are as follows:

1. JDK installation

Put the downloaded installer in the /soft directory

cd /soft

chmod a+x jdk-6u23-linux-i586.bin

./jdk-6u23-linux-i586.bin

mkdir -p /data/conf

mv jdk1.6.0_23/ /data/conf/jdk

Delete the old version from the system

rm -rf /usr/bin/java

rm -rf /usr/bin/javac

Create a link, set a new version

ln -s /data/conf/jdk/bin/java /usr/bin/java

ln -s /data/conf/jdk/bin/javac /usr/bin/javac

View new version information

java-version

javac-version

Check whether the jdk version is 1.6. At this point, the JDK has been installed

2. Tomcat installation

Unzip the compressed file

cd /soft

tar xzvf apache-tomcat-6.0.32.tar.gz

mv apache-tomcat-6.0.32 /data/conf/tomcat

cd /data/conf/tomcat/bin/

Add user

useradd webuser -s /sbin/nologin

chown -R webuser:webuser /data/

tomcat optimization options

(1) Add tomcat administrator

# vi /usr/local/www/tomcat/conf/tomcat-users.xml

Add in the middle of

Where username=”tomcat” is the username and password=”li147258369″ is the password

(2) Modify the JVM

JAVA_OPTS=”-Xms1024m -Xmx1024m -Xmn256m
-Djava.awt.headless=true”

(3) server.xml parameter modification

<Connector port="8080" protocol="HTTP/1.1" 

maxHttpHeaderSize=”8192″ useBodyEncodingForURI=”true”

maxThreads=”600″ Maximum number of connections

redirectPort=”8443″

enableLookups=”false” disable DNS lookups

compression=”on”

compressiOnMinSize=”2048″ compression, compression size

compressableMimeType=”text/html,text/xml,text/Javascript,text/css,text/plain” 

cOnconnectionTimeout=”20000″

disableUploadTimeout=”true”

/>

Set the environment directory

vi /etc/profile

TOMCAT_HOME=/data/conf/tomcat

JAVA_HOME=/data/conf/jdk

JRE_HOME=/data/conf/jdk/jre

export JAVA_HOME JRE_HOME TOMCAT_HOME

Backup tomcat configuration file

cd /data/conf/tomcat/conf

mv server.xml server.xml.bak

Set the tomcat configuration file and configure the virtual host

vi server.xml

Add after

start tomcat

/data/conf/tomcat/bin/startup.sh

View startup process

ps -ef |grep tomcat

Visit the tomcat test page, if the cat head page appears, the installation is successful!

3. Install nginx

Unzip the compressed file

tar zxvf pcre-8.02.tar.gz

cd pcre-8.02/

Compile and install

./configure

make && make install

tar zxvf nginx-0.8.50.tar.gz

cd nginx-0.8.50/

Compile and install

./configure –prefix=/data/conf/nginx
–with-http_stub_status_module

make && make install

Configure nginx configuration file

cd /data/conf/nginx

Backup nginx.conf configuration file

mv nginx.conf nginx.conf.bak

vi nginx.conf

}

Set expiration time for favicon.ico and robots.txt;
Here favicon.ico is 99 days, robots.txt is 7 days and does not record 404 error logs

location ~(favicon. ico) {

       
log_not_found off;

expires 99d;

break;

}

location ~(robots.txt) {

       
log_not_found off;

expires 7d;

break;

}

Set the expiration time of a file; here it is 600 seconds, no access log is recorded

location ^~ /html/scripts/loadhead_1.js {

       
access_log off;

       
root /opt/lampp/htdocs/web;

expires 600;

break;

}

File anti-hotlinking and set expiration time
The return 412 here is a custom http status code, the default is 403, which is convenient for finding the correct hotlink request
“rewrite ^/ http://leech.c1gstudio.com/leech.gif;” displays an anti-leech picture
“access_log off;” does not record access logs, reducing pressure
“expires 3d” browser cache for all files for 3 days

location ~* ^.+/.(jpg|jpeg|gif|png|swf|rar|zip|css|js)$ {

valid_referers none blocked *.c1gstudio.com *.c1gstudio.net
localhost 208.97.167.194;

if ($invalid_referer) {

  rewrite ^/
http://leech.c1gstudio.com/leech.gif;

return 412;

break;

}

       
access_log off;

       
root /opt/lampp/htdocs/web;

expires 3d;

break;

}

Only allow fixed ip to access the website, and add a password

root /opt/htdocs/www;

allow 208.97.167.194;

allow 222.33.1.2;

allow 231.152.49.4;

deny all;

auth_basic “C1G_ADMIN”;

auth_basic_user_file htpasswd;

Convert the files in the multi-level directory into one file to enhance the seo effect
/job-123-456-789.html points to /job/123/456/789.html

rewrite ^/job-([0-9]+)-([0-9]+)-([0-9]+)/.html$
/job/$1/$2/jobshow_$3.html last;

Point a folder under the root directory to the level 2 directory
For example, /shanghaijob/ points to
/area/shanghai/
If you change last to permanent, the address bar of the browser will display /location/shanghai/

rewrite ^/([0-9a-z]+)job/(.*)$ /area/$1/$2 last;

The problem with the above example is that it will not match when accessing /shanghai

rewrite ^/([0-9a-z]+)job$ /area/$1/ last;

rewrite ^/([0-9a-z]+)job/(.*)$ /area/$1/$2 last;

In this way, /shanghai can also be accessed, but the relative links in the page cannot be used,
For example, the real address of ./list_1.html is /area/shanhia/list_1.html and it will become /list_1.html, making it inaccessible.

Then it won’t work if I add automatic jump
(-d $request_filename) It has a condition that it must be a real directory, but my rewrite is not, so it has no effect

if (-d $request_filename){

rewrite ^/(.*)([^/])$ http://$host/$1$2/ permanent;

}

It’s easy to handle after knowing the reason, let me jump manually

rewrite ^/([0-9a-z]+)job$ /$1job/ permanent;

rewrite ^/([0-9a-z]+)job/(.*)$ /area/$1/$2 last;

Redirect when files and directories do not exist:

if (!-e $request_filename) {

proxy_pass http://127.0.0.1;

}
