3、配置Tomcat环境
4、修改Tomcat 2的主配置文件
5、修改启动和关闭脚本文件
6、启动Tomcat并查看
二、nginx和Tomcat的负载均衡和动静分离
1、部署nginx的负载均衡器
2、部署第一台Tomcat
3、部署第二台Tomcat
4、nginx的配置
一、nginx多实例 1、安装jdk
[root@localhost opt]# ls jdk-8u201-linux-x64.rpm rh [root@localhost opt]# rpm -ivh jdk-8u201-linux-x64.rpm java -version
2、安装Tomcat
tar zxvf apache-tomcat-9.0.16.tar.gz mkdir /usr/local/tomcat cp -a apache-tomcat-9.0.16 /usr/local/tomcat/tomcat1 cp -a apache-tomcat-9.0.16 /usr/local/tomcat/tomcat2
3、配置Tomcat环境变量
[root@localhost ~]# vim /etc/profile.d/tomcat.sh #tomcat1 export CATALINA_HOME1=/usr/local/tomcat/tomcat1 export CATALINA_BASE1=/usr/local/tomcat/tomcat1 export TOMCAT_HOME1=/usr/local/tomcat/tomcat1 #tomcat2 export CATALINA_HOME2=/usr/local/tomcat/tomcat2 export CATALINA_BASE2=/usr/local/tomcat/tomcat2 export TOMCAT_HOME2=/usr/local/tomcat/tomcat2 source /etc/profile.d/tomcat.sh
4、修改Tomcat的主配置文件
vim /usr/local/tomcat/tomcat2/conf/server.xml #在22行处进行修改#在69行处进行修改
5、修改启动和关闭脚本文件
vim /usr/local/tomcat/tomcat1/bin/startup.sh export CATALINA_BASE=$CATALINA_BASE1 export CATALINA_HOME=$CATALINA_HOME1 export TOMCAT_HOME=$TOMCAT_HOME1 vim /usr/local/tomcat/tomcat1/bin/shutdown.sh export CATALINA_BASE=$CATALINA_BASE1 export CATALINA_HOME=$CATALINA_HOME1 export TOMCAT_HOME=$TOMCAT_HOME1 vim /usr/local/tomcat/tomcat2/bin/startup.sh export CATALINA_BASE=$CATALINA_BASE2 export CATALINA_HOME=$CATALINA_HOME2 export TOMCAT_HOME=$TOMCAT_HOME2 vim /usr/local/tomcat/tomcat2/bin/shutdown.sh export CATALINA_BASE=$CATALINA_BASE2 export CATALINA_HOME=$CATALINA_HOME2 export TOMCAT_HOME=$TOMCAT_HOME26、启动Tomcat并查看
/usr/local/tomcat/tomcat1/bin/startup.sh /usr/local/tomcat/tomcat2/bin/startup.sh netstat -natp |grep java
二、nginx和Tomcat的负载均衡和动静分离 1、部署nginx均衡服务器
各服务器的配置
nginx服务器的配置：192.168.222.100
tomcat1服务器的配置：192.168.222.10
Tomcat2服务器的配置：192.168.222.20
1、安装依赖包 yum -y install pcre-devel zlib-devel openssl-devel gcc gcc-c++ make 2、新建用户 useradd -M -s /sbin/nologin nginx 3、切换到/opt目录下对压缩包进行解压 cd /opt tar -zxf nginx-1.12.2.tar.gz 4、进入解压目录进行编译，并安装 ./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_stub_status_module make -j 4 && make install 5、让系统识别nginx操作命令 ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin/ 6、让nginx加入系统服务 cd /lib/systemd/system vim nginx.service #!/bin.bash [Unit] Description=nginx After=network.target [Service] Type=forking PIDFile=/usr/local/nginx/logs/nginx.pid ExecStart=/usr/local/nginx/sbin/nginx ExecReload=/usr/bin/kill -s HUP $MAINPID ExecStop=/usr/bin/kill -s QUIT $MAINPID PrivateTmp=true [Install] WantedBy=multi-user.target 7、启动服务并验证 systemctl start nginx netstat -natp |grep nginx
2、部署第一台Tomcat
1、准备Tomcat安装包
[root@localhost opt]# ls
apache-tomcat-9.0.16.tar.gz jdk-8u201-linux-x64.rpm rh
2、安装jdk
rpm -ivh jdk-8u201-linux-x64.rpm
3、修改变量配置文件
vim /etc/profile
export JAVA_HOME=/usr/java/jdk1.8.0_201-amd64
export CLASSPATH=$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar
export PATH=$JAVA_HOME/bin:$PATH
4、刷新配置文件
source /etc/profile
5、切换至/opt下，解压tomcat包
cd /opt
tar -zxf apache-tomcat-9.0.16.tar.gz
6、将解压后的包拷贝至/usr/local/下并重命名
cp -r apache-tomcat-9.0.16 /usr/local/tomcat
7、添加用户并设置属主属组
useradd -s /sbin/nologin tomcat
chown tomcat:tomcat /usr/local/tomcat -R
8、新建服务文件
vim /etc/systemd/system/tomcat.service
[Unit]
Description=Tomcat
#After=syslog.target network.target remote-fs.target nss-lookup.target
After=syslog.target network.target
[Service]
Type=forking
ExecStart=/usr/local/tomcat/bin/startup.sh
ExecStop=/usr/local/tomcat/bin/shutdown.sh
RestartSec=3
PrivateTmp=true
User=tomcat
Group=tomcat
[Install]
WantedBy=multi-user.target
9、开启，查看是否成功启动
systemctl start tomcat
netstat -ntap |grep 8080
10、切换至webapp下，新建test目录
cd /usr/local/tomcat/webapps/
mkdir test
11、建立动态页面文件
vim test/index.jsp
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
JSP test1 page
<% out.println("动态页面1,http://www.test1.com");%>
11、修改主配置文件
vim /usr/local/tomcat/conf/server.xml
删除原来的站点模块
添加
12、重启服务
systemctl restart tomcat.service

apache-tomcat-9.0.16.tar.gz jdk-8u201-linux-x64.rpm
2、安装jdk
rpm -ivh jdk-8u201-linux-x64.rpm
3、修改环境配置文件
vim /etc/profile
export JAVA_HOME=/usr/java/jdk1.8.0_201-amd64
export CLASSPATH=$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar
export PATH=$JAVA_HOME/bin:$PATH

<% out.println("动态页面1,http://www.test2.com");%>
11、修改主配置文件
vim /usr/local/tomcat/conf/server.xml
删除原来的站点模块
添加
12、重启服务
systemctl restart tomcat.service
3、nginx配置
1. #切换至/usr/local/nginx/html/目录下
cd /usr/local/nginx/html/
2. #创建test文件夹，并在里面创建静态网页
mkdir test
cd test
vim test.html
this is static test web !
3. 拖一张图片至test下改名为1.jpg
b.jpg
4. 配置主配置文件
vim /usr/local/nginx/conf/nginx.conf
#配置负载均衡服务器列表，weight参数表示权重，权重越高，被分配到的概率越大
#gzip on;
upstream tomcat_server {
server 192.168.222.10:8080 weight=1;
server 192.168.222.20:8080 weight=1;
}
#动静分离
location ~ .*.jsp$ {
proxy_pass http://tomcat_server;
proxy_set_header HOST $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
#静态图片正则
location ~* .*.(jpg|html|png|gif)$ {
root /usr/local/nginx/html/test;
}
location / {
root html;
index index.html index.htm;
}
