lnmt服务的搭建及其负载轮询

1、前提条件

准备三台服务器

服务器 ip 部署
服务端 192.168.7.10 mysql、nginx、tomcat
客户端1 192.168.7.11 tomcat9
客户端2 192.168.7.12 tomcat9

三台同时关闭防火墙

# systemctl stop firewalld
# systemctl disable firewalld
#  setent 0

2、server端部署

2.1安装nginx

nginx加入systemctl启动脚本:https://files.cnblogs.com/files/liuzhijun666/nginx启动脚本.rar

nginx 下载地址: :http://nginx.org/download/nginx-1.14.0.tar.gz

#  yum -y install pcre-devel openssl openssl-devel gd-devel lrzsz
#  yum -y groups mark install ‘Development Tools‘ 
#  useradd -r -M -s /sbin/nologin nginx
//创建日志目录
# mkdir -p /var/log/nginx
# chown -R nginx.nginx /var/log/nginx
# wget http://nginx.org/download/nginx-1.14.0.tar.gz
# tar -xf nginx-1.14.0.tar.gz
nginx-1.14.0.tar.gz nginx-1.14.0
# pwd
/root/nginx-1.14.0
# ./configure --prefix=/usr/local/nginx \		//编译
--user=nginx --group=nginx \ 
--with-debug \ 
--with-http_ssl_module --with-http_realip_module \ 
--with-http_image_filter_module \ 
--with-http_gunzip_module \ 
--with-http_gzip_static_module \ 
--with-http_stub_status_module \ 
--http-log-path=/var/log/nginx/access.log \ 
--error-log-path=/var/log/nginx/error.log
#  make -j $(grep ‘processor‘ /proc/cpuinfo | wc -l) && make install 		//安装
# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
# cd /usr/local/nginx/sbin/
# ls
nginx 
# cd /etc/init.d
# rz	//上传ngin的启动脚本
# ls
...  nginx .....
# chmod +x nginx
# source nginx	//执行该脚本
# systemctl restart nginx
# ss -antl

3.2安装mysql

下载地址: https://dev.mysql.com/downloads/mysql/

# yum -y install ncurses-devel openssl-devel openssl cmake mariadbdevel
# tar xf mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz ?-C /usr/local/

# groupadd -r mysql    //mysql创建组和用户
# useradd -M -s /sbin/nologin -g mysql mysql
# chown -R mysql.mysql mysql
# echo "export PATH=/usr/local/mysql/bin/:$PATH" > /etc/profile.d/mysql.sh       //环境变量

LISTEN     0      80                    					:::3306         #mysql端口号

3、部署tomcat

tomcat9 下载地址:

# yum -y install java-1.8.0-openjdk java-1.8.0-openjdk-devel  	//下载java
# wget https://mirror.bit.edu.cn/apache/tomcat/tomcat-9/v9.0.36/bin/apache-tomcat-9.0.36.tar.gz
# ls
apache-tomcat-9.0.36.tar.gz
# tar -xf apache-tomcat-9.0.36.tar.gz -C /usr/local
# echo "export PATH=/usr/local/apache-tomcat-9.0.33/bin:$PATH" > /etc/profile.d/tomcat.sh  //环境变量
# startup.sh 
# ss -antl
State       Recv-Q Send-Q               Local Address:Port                              Peer Address:Port              
LISTEN      0      128                              *:80                                           *:*                  
LISTEN      0      128                              *:22                                           *:*                  
LISTEN      0      100                      127.0.0.1:25                                           *:*                  
LISTEN      0      100                             :::8080                                        :::*                  
LISTEN      0      128                             :::22                                          :::*                  
LISTEN      0      100                            ::1:25                                          :::*                  
LISTEN      0      1                 ::ffff:127.0.0.1:8005                                        :::*                  
LISTEN      0      80                              :::3306                                        :::*    

3、实现负载均衡

客户端1:

#  cd /usr/local/apache-tomcat-9.0.36/webapps/
# mkdir test
# cd test
# vim index.jsp
<html>
<head>
<title>第一个</title>
</head>
<body>
1111
<body>
</html>

客户端2:

#  cd /usr/local/apache-tomcat-9.0.36/webapps/
# mkdir test
# cd test
# vim index.jsp
<html>
<head>
<title>第二个</title>
</head>
<body>
2222
<body>
</html>

服务端

修改配置文件:/usr/local/nginx/conf/nginx.conf

......
#添加
upstream www{
           server 192.168.7.12:8080;		#客户端2
           server 192.168.7.11:8080;		#客户端1
	   
        }
server {
		listen       80;					# 端口
         server_name  xxx.example.com;		#设置域名
	    access_log  logs/host.access.log;	#指定日志文件
 location  ~*/test/*.(do|jsp) {							#两个客户端的test
         proxy_pass   http://www;		#www要与upstream 一样
	    index index.html index.htm;
   }

}
......
