我是靠谱客的博主傲娇冬瓜，最近开发中收集的这篇文章主要介绍LNMT部署详细步骤并实现动静分离和负载均衡，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

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
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
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current

100  1572  100  1572    0     0   9484      0 --:--:-- --:--:-- --:--:--  9527
[root@linfan yum.repos.d]# sed -i 's/$releasever/7/g' /etc/yum.repos.d/163.repo
[root@linfan yum.repos.d]# sed -i 's/enabled=0/enabled=1/g' /etc/yum.repos.d/163.repo
[root@linfan yum.repos.d]# yum clean all
yum.repos.d]# yum -y install epel-release 
Loaded plugins: fastestmirror
Cleaning repos: base centosplus extras updates
Cleaning up everything
Maybe you want: rm -rf /var/cache/yum, to also free up space taken by orphaned data from disabled or removed repos
Cleaning up list of fastest mirrors

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
...
...
 -->
<Server port="8006" shutdown="SHUTDOWN">//修改为8006
  <Listener className="org.apache.catalina.startup.VersionLoggerListener" />
  <!-- Security listener. Documentation at /docs/config/listeners.html
  <Listener className="org.apache.catalina.security.SecurityListener" />
  -->
...
...
  -->
    <Connector port="8081" //修改为8081
    protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8444" />//修改为8444
    <!-- A "Connector" using the shared thread pool-->
    <!-- 
    ...
    ...
     <Connector port="8010" protocol="AJP/1.3" redirectPort="8444" />//修改为8010 修改为8444

    <!-- An Engine represents the entry point (within Catalina) that processes

在2个Tomcat上写不同字样的java页面

tomcat1 写“666”
tomcat2写“888”

[root@linfan src]# cd /usr/local/tomcat1/webapps/
[root@linfan webapps]# ls

[root@linfan webapps]# mkdir test
[root@linfan webapps]# cd test
[root@linfan test]# vim index.jsp

      <%
         out.println("666");
      %>

配置mysql

[root@linfan ~]# ln -sv /usr/local/mysql/include/ /usr/local/include/mysql
‘/usr/local/include/mysql’ -> ‘/usr/local/mysql/include/’
[root@linfan ~]# echo '/usr/local/mysql/lib' > /etc/ld.so.conf.d/mysql.conf
[root@linfan ~]# ldconfig -v

生成配置文件

[root@linfan ~]# cat > /etc/my.cnf <<EOF
> [mysqld]
> basedir = /usr/local/mysql
> datadir = /opt/data
> socket = /tmp/mysql.sock
> port = 3306
> pid-file = /opt/data/mysql.pid
> user = mysql
> skip-name-resolve
> EOF

配置服务启动脚本

[root@linfan ~]# cp -a /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
[root@linfan ~]# sed -ri 's#^(basedir=).*#1/usr/local/mysql#g' /etc/init.d/mysqld
[root@linfan ~]# sed -ri 's#^(datadir=).*#1/opt/data#g' /etc/init.d/mysqld

启动mysql

[root@linfan ~]# service mysqld start

修改密码
使用临时密码修改

[root@linfan ~]# mysql -uroot -p
Enter password:

配置nginx

在配置文件中配置nginx作为后端服务器192.168.24.131中2个tomcal的反向代理

[root@linfan ~]# vim /usr/local/nginx/conf/nginx.conf
...
...
http {
    include       mime.types;
    default_type  application/octet-stream;

    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';

    #access_log  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;
//在此添加以下内容
   upstream tomcat {
                      server 192.168.24.131:8080;
                      server 192.168.24.131:8081;

       }    

    server {
        listen       80;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;
 location / {
            root   html;
            index  index.html index.htm;
            在此添加以下内容
                       }
       location ~* .(jsp|do)$ {
                     proxy_pass http://tomcat;
        }

测试语法并加载nginx

[root@linfan ~]# nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
[root@linfan ~]# nginx -s reload

在ngin的网页根目录下面写入内容

[root@linfan logs]# cd /usr/local/nginx/html/
[root@linfan html]# echo "111" >> index.html
