nginx+tomcat+jvm+keepalived部署实验手册
简单拓扑如下：nginx（主负载均衡器）：192.168.0.130
nginx（从负载均衡器）：192.168.0.136
VIP地址： 192.168.0.135
tomcat1的IP 192.168.0.131
tomcat2的IP 192.168.0.140
布置整个环境用到的软件为：
apache-tomcat-6.0.29.tar.gz
jdk-6u23-linux-i586.bin
nginx-0.8.53.tar.gz
nginx-upstream-jvm-route-0.1.tar.gz
pcre-8.10.tar.gz
keepalived-1.1.15.tar.gz
实验运行的操作系统：centos5.3
一、 nginx服务器的安装和配置(192.168.0.130,192.168.0.136)
1. 安装openssl-devel
yum –y installopenssl-devel
2. 安装pcre
cd /usr/local
wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.10.tar.gz
tar -zxvf pcre-8.10.tar.gz
cd pcre-8.10
./configure
make && make install
cp /usr/local/lib/libpcre.a /usr/include/pcre/libpcre.a
cp /usr/local/lib/libpcre.a /usr/include/pcre/libpcre.la
cp /usr/local/include/pcre.h /usr/include/pcre/pcre.h
mkdir /usr/include/pcre/.libs
cp /usr/local/lib/libpcre.a /usr/include/pcre/.libs/libpcre.a
cp /usr/local/lib/libpcre.a /usr/include/pcre/.libs/libpcre.la
cp /usr/local/include/pcre.h /usr/include/pcre/.libs/pcre.h
安装pcre-devel
yum –y install prce-devel
3．nginx+jvm-router安装
添加nginx使用的用户和组
# groupadd www #nginx使用的组；
# useradd -g www www #nginx使用用户；
cd /usr/local
到http://code.google.com/p/nginx-upstream-jvm-route/downloads/list 下载 nginx-upstream-jvm-route-0.1.tar.gz
tar -zxvf nginx-upstream-jvm-route-0.1.tar.gz
wget http://www.nginx.org/download/nginx-0.8.53.tar.gz
tar -zxvf nginx-0.8.53.tar.gz
cdnginx-0.8.53
patch -p0 < ../nginx_upstream_jvm_route/jvm_route.patch
./configure --user=www --group=www --prefix=/usr/local//nginx --with-http_stub_status_module --with-http_ssl_module--add-module=/usr/local/nginx_upstream_jvm_route/
make && make install
4．Nginx的配置文件 (主、辅配置一样)
vi/usr/local/nginx/conf/nginx.conf
userwwwwww;
worker_processes1;
#error_loglogs/error.log;
#error_loglogs/error.lognotice;
#error_loglogs/error.loginfo;
#pid logs/nginx.pid;
events {
worker_connections1024;
}
http {
include mime.types;
default_typeapplication/octet-stream;
keepalive_timeout120;
tcp_nodelay on;
upstream oa.com {
server 192.168.0.131:8080 srun_id=a;
server 192.168.0.140:8080 srun_id=b;
jvm_route $cookie_JSESSIONID|sessionid reverse;
}
server {
listen 80;
server_nameoa.com;
#charset koi8-r;
#access_loglogs/host.access.logmain;
location / {
root /home/oa;
indexindex.jsp index.html index.htm;
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://oa.com;
}
log_format access '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" $http_x_forwarded_for';
access_log /var/log/access.log access;
}
}
5. 启动nginx
/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
Nginx 的重启：
ps -ef | grep "nginx: master process" | grep -v "grep" | awk -F ' ' '{print $2}'
kill -HUB3944
/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
6.设置ngnix为系统开机自动启动
#vi /etc/rc.d/rc.local
/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
