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

LNMT部署详细步骤并实现动静分离和负载均衡_第1张图片
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

java环境安装

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
openjdk version "1.8.0_181"
OpenJDK Runtime Environment (build 1.8.0_181-b13)
OpenJDK 64-Bit Server VM (build 25.181-b13, mixed mode)

tomcat部署

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
apache-tomcat-9.0.8  bin  doudou  etc  games  include  lib  lib64  libexec  nginx  sbin  share  src
[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
[root@linfan local]# ll

lrwxrwxrwx   1 root root  20 Sep  5 01:37 tomcat2 -> apache-tomcat-9.0.8/

为了避免端口冲突，修改tomcat配置文件的端口号（修改其中一个即可）在这里我修改tomcat1的配置文件
tomcat1的端口改为8081

[root@linfan ~]# vim /usr/local/tomcat1/conf/server.xml
...
...
 -->
//修改为8006
  
  
...
...
  -->
    //修改为8444
