Centos7+nginx+tomcat 集群部署实战

来源：互联网发布：网络投资平台有哪些编辑：程序博客网时间：2024/06/13 08:48

1:安装centos7(链接：http://pan.baidu.com/s/1o80x36a 密码：xuwb)，安装步骤自己百度，并克隆4个虚拟机

我的ip为(192.168.72.129 192.168.72.130 192.168.72.131 192.168.72.132)

2:下载xshell,连接上这四台linux

3:在192.168.72.129安装nginx(链接：http://pan.baidu.com/s/1skAQ3X7 密码：lwrz)

安装步骤:先在192.168.72.129创建文件夹

------------------------nginx开始安装---------------------------

cd /usr/local

mkdir software/nginx

cd /usr/local/software/nginx

rz 这里把下载好的nginx复制到/usr/local/software/nginx目录下,

tar -xzvf nginx-1.8.1.tar.gz

cd /usr/local/software/nginx/nginx-1.8.1

./configure

这里会报错,一些包找不到

安装缺失的包

yum -y install pcre-devel

yum -y install openssl-devel

安装完成后执行

./configure

make

make install

测试nginx

cd /usr/local/nginx/sbin

./nginx -t

启动nginx

./nginx

访问nginx 192.168.72.129:80

--------------------nginx安装完成-----------------------

4:4个机器上安装tomcat,并分别部署测试项目(链接：http://pan.baidu.com/s/1i4VzLtF 密码：qnxv)

安装步骤略

5:修改nginx配置文件

#user nobody;
#启动进程,通常设置成和cpu的数量相等
worker_processes 1;

#全局错误日志及PID文件
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;

#pid        logs/nginx.pid;

events {
   #epoll是多路复用IO(I/O Multiplexing)中的一种方式,但是仅用于linux2.6以上内核,可以大大提高nginx的性能
    use   epoll;
   #单个后台worker process进程的最大并发链接数
    worker_connections 1024;
}

#设定http服务器，利用它的反向代理功能提供负载均衡支持
http {
   #设定mime类型,类型由mime.type文件定义
    include       mime.types;
    default_type application/octet-stream;
   #设定日志格式


#设定负载均衡的服务器列表
upstream tomcat {
   #weigth参数表示权值，权值越高被分配到的几率越大

6:启动tomcat,启动tomcat,观看效果

浏览器输入(http://192.168.72.129:8888/nginx/)，刷新看效果

每刷新一次,就切换一下

7:停止某个tomcat，观看效果.再启动观看效果
