2.jdk
Automatic networking: Return to the root directory vi/etc/sysconfig/network-scripts/ifcfg-eth0 and put ONBOOT=no inside
no changes to yes, then: qi saves and exits
Download yum install lrzsz -y
Once the download is complete, upload the file to the server directly from the command line rz/download to the local sz+file name
Command rz to return and upload the local jdk package
Configuring environment variables for jdk
Vi. Bash_ Profe Enter
export JAVA_HOME=/usr/lib/jvm/jdk1.8.0_261 export PATH=$JAVA_HOME/bin:$PATH
Then the java-version check
2. Another way to install jdk
1. Check if JDK is installed on the current system
2. Detect system JDK default installation package
Command: rpm-qa | grep java: Command means to search for Java and view installation package files.
3. Uninstall OpenJDK (some versions of the linux system come with it)
Unload command: rpm-e - nodeps name or yum remove *openjdk*
Then enter the command again to see the uninstallation: java-version
4. Install JDK
Choose to download the version of JDK you want on the JDK website. After downloading, upload the JDK installation package you need to install to the folder specified by your Linux system and command it to go to that folder.
1. Enter the user's root directory and create a folder downfile to save the uploaded files.
2. Use XFTP (any transfer tool) to upload the local file JDK to the directory specified by the Linux system/home/downfile.
3. Enter the downfile directory.
4. Unzip the JDK file into the / usr/lib/jvm directory. (This is the default directory for installing JDK on Linux. It is recommended to update the installation path/usr/local/...)
####Upload JDK downloaded from Oracle's official website to this directory using Xftp: check for existence after uploading cd downfile ll tar -xvf jdk-8u261-linux-x64.tar.gz -C /usr/lib/jvm cd /usr/lib/jvm ll ####Configuration environment vim /etc/profile ####Add at beginning or end export JAVA_HOME=/usr/lib/jvm/jdk1.8.0_261 export PATH=$JAVA_HOME/bin:$PATH export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
