实验环境
| 主机名 | IP | 操作系统 | 所需配置 |
|---|---|---|---|
| A | 192.168.24.131 | centos7 | 2个Tomcat |
| B | 192.168.24.146 | centos7 | mysql，nginx |
实验需求
主机B作为nginx服务器，主机A作为2个Tomcat服务器，客户端发来的请求首先经由nginx处理，由nignx反代至后端的Tomcat服务器实现负载均衡
实验部署如下
在主机A操作如下
部署2个Tomcat服务器
实验准备
关闭防火墙以及SELINX
[root@linfan ~]# systemctl stop firewalld
[root@linfan ~]# systemctl disable firewalld
[root@linfan ~]# sed -ri 's/^(SELINUX=).*/\1disabled/g' /etc/selinux/config
[root@linfan ~]# setenforce 0
setenforce: SELinux is disabled安装yum源
[root@linfan ~]# cd /etc/yum.repos.d/
[root@linfan yum.repos.d]# curl -o 163.repo http://mirrors.163.com/.help/CentOS7-Base-163.repo

安装jdk环境
[root@linfan ~]# yum -y install java-1.8.0-openjdk java-1.8.0-openjdk-devel查看安装版本
[root@linfan ~]# java -version

下载tomcat
[root@linfan ~]cd /usr/src
[root@linfan src]# wget https://archive.apache.org/dist/tomcat/tomcat-9/v9.0.8/bin/apache-tomcat-9.0.8.tar.gz
[root@linfan src]# ls
apache-tomcat-9.0.8.tar.gz debug kernels解压部署
因为要部署2个tomcal，所以这里要实现2次解压
//第一次解压
root@linfan src]# tar xf apache-tomcat-9.0.8.tar.gz -C /usr/local/
[root@linfan src]# cd /usr/local/
[root@linfan local]# mv apache-tomcat-9.0.8/ doudou //解压后重命名为doudou，防止第二次解压在同一目录下同名
[root@linfan local]# ls doudou
bin conf lib LICENSE logs NOTICE RELEASE-NOTES RUNNING.txt temp webapps work
//第二次解压
[root@linfan local]# cd /usr/src
[root@linfan src]# ls
apache-tomcat-9.0.8.tar.gz debug kernels
[root@linfan src]# tar xf apache-tomcat-9.0.8.tar.gz -C /usr/local/
[root@linfan src]# cd /usr/local/
[root@linfan local]# ls

[root@linfan local]# ln -s doudou/ tomcat1 //软连接为tomcat1
[root@linfan local]# ln -s apache-tomcat-9.0.8/ tomcat2 //软连接为tomcat2

tomcat1的端口改为8081
