一、环境介绍
1、系统：centos7
2、应用部署：weblogic 12c
2、nginx版本：nginx-1.7.2
3、应用1（weblogic1）：192.168.29.149:7018/realware
4、应用2（weblogic2）：192.168.29.150:7012/realware
5、nginx服务器：192.168.29.152:8080
二、下载nginx-1.7.2
mkdir -p /opt/src
cd opt/src
wget http://nginx.org/download/nginx-1.7.2.tar.gz
tar -xvf nginx-1.7.2.tar.gz
三、下载主动健康检查插件
cd opt/src
yum -y install wget
wget https://codeload.github.com/yaoweibin/nginx_upstream_check_module/zip/master
yum install unzip -y
unzip master.zip
四、安装主动健康检查插件
yum install patch -y
cd /opt/src/nginx-1.7.2
patch -p1 < /opt/src/nginx_upstream_check_module-master/check_1.7.2+.patch
五、编译安装nginx
cd /opt/src/nginx-1.7.2
yum -y install gcc pcre-devel zlib-devel openssl openssl-devel
./configure –prefix=/usr/local/nginx –add-module=/opt/src/nginx_upstream_check_module-master
make
make install
六、反向代理被动健康检查与反向代理主动健康检查
1、反向代理被动健康检查
配置文件修改：vim /usr/local/nginx/conf/nginx.conf
#user nobody;
worker_processes 1;
error_log logs/error.log;
error_log logs/error.log notice;
error_log logs/error.log info;
pid logs/nginx.pid;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
#upstream 后面要用nginx所在服务器的IP，不然可能会导致网络的css、js等外部连接无法调用。
upstream 192.168.29.152 {
#以5s为周期，5秒内只要有一次访问失败，则这5s内不会再向该ip发起访问。可以根据情况调整。
server 192.168.29.150:7012 max_fails=1 fail_timeout=5s;
server 192.168.29.149:7018 max_fails=1 fail_timeout=5s;
}
server {
listen 8080;
#server_name 后面要用web应用的名称
server_name realware;
location / {
proxy_pass http://192.168.29.152; #这里的IP要与upstream保持一致。
proxy_set_header X-Forwarded-Host $host;

}
}
}
2、反向代理主动健康检查
配置文件修改：vim /usr/local/nginx/conf/nginx.conf

}
}
五、启动nginx
cd /usr/local/nginx/sbin
./nginx
六、检验结果
在浏览器输入http://192.168.29.152:8080/realware 查看是否配置成功；
在浏览器输入http://192.168.29.152:8080/status
