tomcat9.0 latest version of the first experience

1,rpm Mode installation Jdk8

software Preparation: Download Jdk8 first
: http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html.

Download the linux64-bit version of the RPM installation package, wget http://download.oracle.com/otn-pub/java/jdk/8u66-b17/jdk-8u66-linux-x64.rpm.

Source: http://download.oracle.com/otn-pub/java/jdk/8u66-b17/jdk-8u66-linux-x64.tar.gz.

wget下载报错，说：正在连接 edelivery.oracle.com|23.0.182.140|:443... 已连接。错误: 证书通用名 “www.oracle.com” 与所要求的主机名 “edelivery.oracle.com” 不符。要以不安全的方式连接至 edelivery.oracle.com，使用‘--no-check-certificate’。

So after the local PC browser opens the download, it is uploaded to the Linux server via Securefx.

RPM package installation, default in/usr/java path:

RPM-IVH jdk-8u66-linux-x64-demos.rpm

2. Add JDK8 configuration at the end of the/etc/profile file

vim /etc/profile JAVA_HOME=/usr/java/jdk1.8.0_66PATH=$JAVA_HOME/bin:$PATHCLASSPATH=$JAVA_HOME/jre/lib/ext:$JAVA_HOME/lib/tools.jarexport PATH JAVA_HOME CLASSSPATH

3, let JDK8 configuration take effect

Source/etc/profile make profile file effective immediately

4,check JDK Version

[Root@oracle_standbyJdk1.8.0_66]# echo $JAVA _home/usr/java/jdk1.8.0_66[Root@oracle_standbyJdk1.8.0_66]# echo $CLASSPATH/usr/java/jdk1.8.0_66/jre/lib/Ext:/usr/java/jdk1.8.0_66/lib/tools.jar[root@oracle_standbyJdk1.8.0_66]# echo $PATH/usr/java/jdk1.8.0_66/Bin:/usr/lib64/qt-3.3/Bin:/usr/local/sbin:/usr/local/Bin:/sbin:/Bin:/usr/sbin:/usr/Bin:/root/bin[root@oracle_standbyJdk1.8.0_66]# java-versionJava version"1.7.0_09-icedtea"OpenJDK Runtime Environment(rhel-2.3.4.1. el6_3-x86_64)OpenJDK  --Bit Server VMS(Build23.2-B09, mixed mode) [root@oracle_standbyJdk1.8.0_66]# 

5, configure default JDK (usually this step can be omitted)

Some Linux distributions already have default JDK, such as OPENJDK. So in order to make the JDK version we just installed can be the default JDK version, we will also make the following configuration.
Execute the following command:
sudo update-alternatives–install/usr/bin/java Java/usr/java/jdk1.8.0_66/bin/java 300
sudo update-alternatives–install/usr/bin/javac Javac/usr/java/jdk1.8.0_66/bin/javac 300
Note: If the above two commands do not find a path problem, just restart the machine and repeat the above two lines of code is OK.

Execute the following code to see the current various JDK versions and configurations:
sudo update-alternatives–config java
