Linode Center OS 6.5(x64) 用Nginx 反向代理多个Tomcat 负载均衡。
#安装Java JDK
yum install java-1.7.0-openjdk.x86_64
#安装Tomcat
cd /usr/local
mkdir tomcat
wget http://archive.apache.org/dist/tomcat/tomcat-6/v6.0.37/bin/apache-tomcat-6.0.37.tar.gz
tar -zxf apache-tomcat-6.0.37.tar.gz
mv apache-tomcat-6.0.37 tomcat6-8080
cp -R tomcat6-8080 tomcat6-8081
vim tomcat6-8081/conf/server.xml
#修改以下位置

#安装Nginx
#1.安装所需环境
yum -y install gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel 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-server krb5-devel libidn libidn-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers
yum install pcre-devel zlib-devel
#2.安装Nginx
wget http://nginx.org/download/nginx-1.0.14.tar.gz
tar xzf nginx-1.0.14.tar.gz
cd nginx-1.0.14
./configure --prefix=/usr/local/nginx
make && make install
#配置Nginx实现负载均衡
cp /usr/local/nginx/conf/nginx.conf /usr/local/nginx/conf/nginx.conf.bak
vim /usr/local/nginx/conf/nginx.conf
删除 nginx.conf 中全部内容 并加入以下内容
