Implementation of Tomcat load balancing with Nginx reverse proxy in Centos6.5 system

1. View the kernel and system parameters and versions of the current system.

[Email protected] ~]# uname-alinux node1 2.6.32-431.el6.x86_64 #1 SMP Fri Nov 03:15:09 UTC-x86_64 x86_64 x86_64 Gnu/linux[[email protected] ~]# Cat/etc/issuecentos release 6.5 (Final) Kernel \ r on an \m

2. Install Nginx.

1) Install the GCC compiler and related tools and dependent libraries.

[Email protected] ~]# yum-y install gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype Freetype-dev El libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel Curl Curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel OpenSSL openssl-devel openldap openldap-devel NS S_ldap openldap-clients openldap-servers Pcre

2) Compile and install the Pcre library.

PCRE (perl Compatible Regular Expressions) is a Perl library that includes regular Perl-compatible expressions. The main function of Pcre is to make Nginx support HTTP rewrite module.

Creates a directory that specifies the placement of the compressed package.

[[email protected] ~]# mkdir-p/taokey/tools[[email protected] ~]# cd/taokey/tools/[[email protected] tools]# TAR-ZXF p Cre-8.33.tar.gz[[email protected] pcre-8.33]#/configure[[email protected] pcre-8.33]# make && make install[[ Email protected] nginx-1.5.8]#/configure--with-http_stub_status_module--with-http_ssl_module--prefix=/data/ Nginx[[email protected] nginx-1.5.8]# make && make install

Note: The installation successfully started Nginx, you may encounter the following error,

[Email protected] nginx-1.5.8]#/data/nginx/sbin/nginx-t/data/nginx/sbin/nginx:error while loading GKFX libraries: Libpcre.so.1:cannot open Shared object file:no such file or directory

Workaround:

[Email protected] ~]# cd/lib64/[[email protected] lib64]# ln-s libpcre.so.0.0.1 libpcre.so.1

3) Start Nginx again to see the next process and port.

[[Email protected] lib64]# /data/nginx/sbin/nginx -tnginx: the configuration  file /data/nginx/conf/nginx.conf syntax is oknginx: configuration file  /data/nginx/conf/nginx.conf test is successful[[email protected] lib64]# / data/nginx/sbin/nginx [[email protected] lib64]# ps -ef | grep  nginxroot      8991     1  0 16:43  ?         00:00:00 nginx: master process /data/ nginx/sbin/nginxnobody    8992  8991  0 16:43 ?         00:00:00 nginx: worker process root       8994  1907  0 16:44 pts/1    00:00:00  grep nginx[[email protected] lib64]# netstat -anpt | grep nginxtcp         0      0 0.0.0.0:80                   0.0.0.0:*                    LISTEN       8991/nginx

3. Configure the Nginx Web reverse proxy to achieve two Tomcat load balancing:

The Nginx configuration file is as follows:[[email protected] ~]# cat /data/nginx/conf/nginx.confuser  root; worker_processes  1; #error_log   logs/error.log  info;pid  /data/nginx/ logs/nginx.pid;worker_rlimit_nofile 65535;events {    use epoll;     worker_connections 65535;    multi_accept on;} http {    include       mime.types;     default_type  application/octet-stream;    charset    utf-8;    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;    sendfile       on;     tcp_nopush     on;    keepalive_timeout  60;     server_tokens  off;    limit_rate_after 3m;     limit_rate 512k;     tcp_nodelay on;     client_header_buffer_size 256k;    large_client_header_buffers 4 256k ;        # define nginx proxy module         proxy_http_version 1.1;         proxy_connect_timeout 60;        proxy_read_timeout 60;         proxy_send_timeout 60;        proxy_ buffer_size   16k;        proxy_buffers        4 64k;        proxy_busy_buffers_ Size     128k;        proxy_temp_file_write_ size 128k;        proxy_headers_hash_max_size 51200;         proxy_headers_hash_bucket_size 6400;      # Define Gzip compression module    gzip on;     gzip_vary on;    gzip_min_length  1k;     gzip_buffers    &Nbsp;4 16k;    gzip_http_version 1.0;    gzip_comp_level  2;    gzip_types       text/plain  application/x-javascript text/css application/xml;    # define  realserver pool    upstream  taokey.com {         ip_hash;        server 192.168.1.15:8080   max_fails=0  weight=5;        server  192.168.1.19:8080  max_fails=0  weight=5;   }    server  {        listen       80;         server_name  taoyake.cn www.taoyake.cn;         location / {                 proxy_set_header Host  $host;                 proxy_set_header X-Real-IP        $remote _addr;                proxy_ set_header x-forwarded-for  $proxy _add_x_forwarded_for;                 proxy_pass  http://taokey.com;                 expires 1d;                  access_log   logs/host.access.log  main;        }        &nbSp;       # define 404 502 503 504 error  page        error_page   404               /404.html;         error_page   500 502 503 504  /50x.html;         location = /50x.html {             root   html;         }    }}
