TOMCAT容器部署和tomcat虚拟主机及其优化

TOMCAT容器部署和tomcat虚拟主机及其优化

一、Tomcat部署

【1】上传JDK软件包和tomcat压缩包并解压

cd /opt 
mkdir tomcat
rpm -ivh jdk-8u201-linux-x64.rpm
tar zxvf apache-tomcat-9.0.16.tar.gz -C /usr/local

【2】声明JDK全局变量

cd /usr/java/jdk1.8.0_201-amd64/
pwd
/usr/java/jdk1.8.0_201-amd64/
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
source /etc/profile

【3】查看Java版本是否改变

java -version
   java version "1.8.0_201"
   Java(TM) SE Runtime Environment (build 1.8.0_201-b09)
   Java HotSpot(TM) 64-Bit Server VM (build 25.201-b09, mixed mode)

【4】优化命令为系统识别

ln -s /usr/local/apache-tomcat-9.0.16/bin/shutdown.sh /usr/bin/
ln -s /usr/local/apache-tomcat-9.0.16/bin/startup.sh /usr/bin/

【5】启动tomcat并验证

/usr/bin/startup.sh 
netstat -natp |grep 8080

【6】优化启动

vim /usr/java/jdk1.8.0_201-amd64/jre/lib/security/java.security
    # In addition, if "file:/dev/random" or "file:/dev/urandom" is
    # specified, the "NativePRNG" implementation will be more preferred than
    # SHA1PRNG in the Sun provider.
    securerandom.source=file:/dev/urandom

二、虚拟主机设置

【1】在tomcat工作目录下创建站点

cd /usr/local//apache-tomcat-9.0.16/webapps/
mkdir kgc benet
vim kgc/index.jsp
   
this is kgc page
vim benet/index.jsp
   
this is benet page

【2】tomcat虚拟主机配置

vim /usr/local/apache-tomcat-9.0.16/conf/server.xml
      
          
      

      
          
       

【3】配置域名

yum install -y bind
vim /etc/named.conf
   listen-on port 53 { any; };
   allow-query     { any; };
vim /etc/named.rfc1912.zones
   zone "kgc.com" IN {
        type master;
        file "kgc.com.zone";
        allow-update { none; };
   };
   zone "benet.com" IN {
        type master;
        file "benet.com.zone";
        allow-update { none; };
   };
cp -p /var/named/named.localhost /var/named/kgc.com.zone
vim /var/named/kgc.com.zone
   www IN  A       192.168.60.10
cp -p /var/named/kgc.com.zone /var/named/benet.com.zone

【4】启动服务和tomcat

systemctl start named
/usr/local/apache-tomcat-9.0.16/bin/shutdown.sh 
/usr/local/apache-tomcat-9.0.16/bin/startup.sh 

【5】访问不同的域名显示不同的结果

www.kgc.com:8080

www.benet.com:8080

三、Tomcat优化

【1】修改tomcat配置文件

vim /usr/local/apache-tomcat-9.0.16/conf/server.xml
     ########指定对那些文件进行压缩

【2】重启tomcat

/usr/local/apache-tomcat-9.0.16/bin/shutdown.sh 
/usr/local/apache-tomcat-9.0.16/bin/startup.sh
