02 tomcat核心概念及使用初步
配置环境
node1: CentOS 6.7 192.168.1.121
CentOS 6 部署Tomcat
[root@node1 ~]# rpm -ivh jdk-7u67-linux-x64.rpm
[root@node1 jdk1.7.0_67]# vim /etc/profile.d/java.sh
export JAVA_HOME=/usr/java/latest
export PATH=$JAVA_HOME/bin:$PATH
[root@node1 jdk1.7.0_67]# . /etc/profile.d/java.sh
[root@node1 ~]# tar xf apache-tomcat-8.0.38.tar.gz -C /usr/local/
[root@node1 ~]# cd /usr/local/
[root@node1 local]# ln -s apache-tomcat-8.0.38/ tomcat
[root@node1 local]# cd tomcat/
[root@node1 tomcat]# vim /etc/profile.d/tomcat.sh
export CATALINA_HOME=/usr/local/tomcat
export PATH=$CATALINA_HOME/bin:$PATH
[root@node1 tomcat]# . /etc/profile.d/tomcat.sh
#启动Tomcat
[root@node1 tomcat]# catalina.sh start
03 tomcat配置与应用
配置环境
node1: CentOS 7.2 192.168.1.131
1、CentOS 7 部署Tomcat
[root@node1 ~]# yum install jdk-8u25-linux-x64.rpm
[root@node1 ~]# vim /etc/profile.d/java.sh
export JAVA_HOME=/usr/java/latest
export PATH=$JAVA_HOME/bin:$PATH
[root@node1 ~]# . /etc/profile.d/java.sh
[root@node1 ~]# tar xf apache-tomcat-8.0.38.tar.gz -C /usr/local/
[root@node1 ~]# cd /usr/local/
[root@node1 local]# ln -s apache-tomcat-8.0.38 tomcat
[root@node1 local]# cd tomcat/
[root@node1 tomcat]# vim /etc/profile.d/tomcat.sh
export CATALINA_HOME=/usr/local/tomcat
export PATH=$CATALINA_HOME/bin:$PATH
[root@node1 tomcat]# . /etc/profile.d/tomcat.sh
#启动Tomcat
[root@node1 tomcat]# catalina.sh start
2、手动添加一个测试应用程序
[root@node1 webapps]# pwd
/usr/local/tomcat/webapps
[root@node1 webapps]# mkdir -p myapp/{lib,classes,WEB-INF,META-INF}
[root@node1 webapps]# tree myapp/
myapp/
├── classes
├── lib
├── META-INF
└── WEB-INF
[root@node1 webapps]# vim myapp/index.jsp
<%@ page language="java" %>
<%@ page import="java.util.*" %>
<html>
<head>
<title>JSP Test Page</title>
</head>
<body>
<% out.println("Hello,world."); %>
</body>
</html>
访问测试页：http://192.168.1.131:8080/myapp/
3、添加访问“Manager App”用户
[root@node1 tomcat]# cd conf/
[root@node1 conf]# vim tomcat-users.xml
添加
<role rolename="manager-gui"/>
<user username="tomcat" password="tomcat" roles="manager-gui"/>
[root@node1 conf]# catalina.sh stop
[root@node1 conf]# catalina.sh start
4、添加访问“Host Manager”用户
[root@node1 conf]# vim tomcat-users.xml
添加
<role rolename="manager-gui"/>
<role rolename="admin-gui"/>
<user username="tomcat" password="tomcat" roles="manager-gui,admin-gui"/>
[root@node1 conf]# catalina.sh stop
[root@node1 conf]# catalina.sh start
[root@node1 conf]# cp server.xml{,.bak}
[root@node1 conf]# vim server.xml
04 tomcat配置与应用
配置环境
node1: CentOS 7.2 192.168.1.131
node12: CentOS 7.2 192.168.1.132
1、定义虚拟主机1
[root@node1 tomcat]# vim conf/server.xml
添加Host段如下：
<Host name="web1.magedu.com" appBase="/data/webapps" unpackWARs="true" autoDeploy="false">
<Context path="" docBase="/data/webapps" reloadable="true" />
<Valve className="org.apache.catalina.valves.AccessLogValve" directory="/data/logs"
prefix="web1_access_log" suffix=".txt"
pattern="%h %l %u %t "%r" %s %b" />
</Host>
[root@node1 tomcat]# mkdir -p /data/{webapps,logs}
[root@node1 tomcat]# cp -r /usr/local/tomcat/webapps/myapp/* /data/webapps/
[root@node1 tomcat]# catalina.sh stop
[root@node1 tomcat]# catalina.sh start
[root@node2 ~]# curl web1.magedu.com:8080/index.jsp
2、定义虚拟主机2
[root@node1 tomcat]# cd /data/webapps/
[root@node1 webapps]# ls
classes index.jsp lib META-INF WEB-INF
[root@node1 webapps]# mkdir ROOT
[root@node1 webapps]# mv classes/ index.jsp lib/ META-INF/ WEB-INF/ ROOT
[root@node1 ~]# cd /usr/local/tomcat/conf/
[root@node1 conf]# vim server.xml
添加Host段如下：
<Host name="web1.magedu.com" appBase="/data/webapps" unpackWARs="true" autoDeploy="true">
<Context path="" docBase="ROOT" reloadable="true" />
<Context path="/shop" docBase="shopxx" reloadable="true" />
<Valve className="org.apache.catalina.valves.AccessLogValve" directory="/data/logs"
prefix="web1_access_log" suffix=".txt"
pattern="%h %l %u %t "%r" %s %b" />
</Host>
[root@node1 conf]# mkdir /data/webapps/shopxx
[root@node1 conf]# catalina.sh stop
[root@node1 conf]# catalina.sh start
[root@node2 ~]# curl web1.magedu.com:8080
3、一个简单的示例
[root@node1 ~]# unzip shopxx-a5-Beta.zip
[root@node1 ~]# cd shopxx-v3.0-Beta/
[root@node1 shopxx-v3.0-Beta]# mv shopxx-3.0Beta/ /data/webapps/
[root@node1 shopxx-v3.0-Beta]# cd /data/webapps/
[root@node1 webapps]# rm -rf shopxx
[root@node1 webapps]# ln -s shopxx-3.0Beta shopxx
[root@node1 webapps]# catalina.sh stop
[root@node1 webapps]# catalina.sh start
[root@node1 webapps]# yum -y install mariadb-server
[root@node1 webapps]# systemctl start mariadb.service
[root@node1 webapps]# mysql
MariaDB [(none)]> grant all on shopxx.* to shopuser@‘localhost‘ identified by ‘shopuserpass‘;
MariaDB [(none)]> grant all on shopxx.* to shopuser@‘127.0.0.1‘ identified by ‘shopuserpass‘;
MariaDB [(none)]> flush privileges;
[root@node1 webapps]# cd shopxx
[root@node1 shopxx]# mv install/ backup
[root@node1 shopxx]# catalina.sh stop
[root@node1 shopxx]# catalina.sh start
4、拒绝某主机对网站的访问
[root@node1 ~]# vim /usr/local/tomcat/conf/server.xml
修改Host段的内容为（修改的内容为Context段）
<Host name="web1.magedu.com" appBase="/data/webapps" unpackWARs="true" autoDeploy="true">
<Context path="" docBase="ROOT" reloadable="true">
<Valve className="org.apache.catalina.valves.RemoteAddrValve"
deny="192\.168\.56\.97"/>
</Context>
<Context path="/shop" docBase="shopxx" reloadable="true" />
<Valve className="org.apache.catalina.valves.AccessLogValve" directory="/data/logs"
prefix="web1_access_log" suffix=".txt"
pattern="%h %l %u %t "%r" %s %b" />
</Host>
[root@node1 ~]# catalina.sh stop
[root@node1 ~]# catalina.sh start
测试成功
5、测试tomcat支持静态图片
[root@node1 ~]# cd /data/webapps/ROOT/
[root@node1 ROOT]# mkdir images
[root@node1 ROOT]# cd images/
[root@node1 images]# ls #上传两个图片
1.jpg 2.jpg
访问：
http://web1.magedu.com:8080/images/1.jpg
能正常访问
[root@node1 ~]# vim /usr/local/tomcat/conf/server.xml
[root@node1 ~]# cd /data/webapps/
[root@node1 webapps]# mv shopxx-3.0Beta/ /root/
[root@node1 webapps]# rm shopxx
[root@node1 webapps]# mkdir shopxx
[root@node1 webapps]# catalina.sh stop
[root@node1 webapps]# catalina.sh start
6、LNMT
（1）用nginx反向解析tomcat全部内容
[root@node2 ~]# yum -y install nginx
[root@node2 ~]# cd /etc/nginx/
[root@node2 nginx]# vim nginx.conf
修改location /段的内容为
location / {
proxy_pass http://192.168.1.131:8080/;
}
[root@node2 nginx]# nginx -t
[root@node2 nginx]# systemctl start nginx.service
（2）用nginx反向解析tomcat指定网站（web1.magedu.com）
[root@node2 nginx]# vim /etc/hosts
添加：
192.168.1.131 web1.magedu.com
[root@node2 nginx]# vim nginx.conf
修改location /段的内容为：
location / {
proxy_pass http://web1.magedu.com:8080/;
}
[root@node2 nginx]# systemctl reload nginx.service
（3）动态内容发往tomcat主机(node1)，静态内容留在本机(node2)
[root@node2 nginx]# vim nginx.conf
添加
index index.jsp index.html;
修改location /段的内容为：
location / {
}
location ~* \.(jsp|do)$ {
proxy_pass http://web1.magedu.com:8080;
}
[root@node2 nginx]# systemctl reload nginx.service
[root@node2 nginx]# mkdir -p /data/webpics/images
[root@node2 nginx]# cd /data/webpics/images/
[root@node2 images]# ls #下载两张图片
1.jpg 2.jpg
[root@node2 images]# vim /etc/nginx/nginx.conf
修改
root /usr/share/nginx/html
为
root /data/webpics;
[root@node2 images]# systemctl reload nginx
7、LAMT
（1）proxy_module_http方式
[root@node2 images]# systemctl stop nginx.service
[root@node2 images]# yum -y install httpd
[root@node2 images]# cd /etc/httpd/
[root@node2 httpd]# vim conf/httpd.conf
注释
#DocumentRoot "/var/www/html"
[root@node2 httpd]# vim conf.d/vhosts.conf
添加以下内容：
<VirtualHost *:80>
ServerName web1.magedu.com
ProxyVia On
ProxyRequests Off
ProxyPreserveHost On
<Proxy *>
Require all granted
</Proxy>
ProxyPass / http://192.168.1.131:8080/
ProxyPassReverse / http://192.168.1.131:8080/
<Location />
Require all granted
</Location>
</VirtualHost>
[root@node2 httpd]# httpd -t
[root@node2 httpd]# systemctl start httpd.service
（2）proxy_module_ajp:
[root@node2 httpd]# vim conf.d/vhosts.conf
<VirtualHost *:80>
ServerName web1.magedu.com
ProxyVia On
ProxyRequests Off
ProxyPreserveHost On
<Proxy *>
Require all granted
</Proxy>
ProxyPass / ajp://192.168.1.131:8009/
ProxyPassReverse / ajp://192.168.1.131:8009/
<Location />
Require all granted
</Location>
</VirtualHost>
[root@node2 httpd]# systemctl start httpd.service
（3）status不使用反向解析
[root@node2 httpd]# vim conf.d/vhosts.conf
在ProxyPass前面添加
ProxyPass /status !
[root@node2 httpd]# vim conf/httpd.conf
