linux install jdk
There are two ways to install jdk: manual installation and yum installation:
1. The installation of yum is as follows:
1.1 Query the version of jdk to be installed
Command: yum -y list java*
1.2 Install jdk1.8
命令：yum install -y java-1.8.0-openjdk.x86_64
1.3 Query jdk version
Command: java -version
In this way, the installation is successful.

2. Manual installation is as follows:
2.1 Download the jdk1.8 compressed package:

2.3 Upload jdk to linux and unzip:
Use xftp or xshell to transfer files directly.
If it is xshell to directly drag files, a package is required:
yum -y install lrzsz
After uploading, you can perform the following operations, insert the picture description here
Go to the folder where we store the software, put the compressed package just downloaded in this directory and unzip
Command: tar -zxvf jdk-8uxxx-linux-x64.tar.gz (jdk-8...this is the name of the jdk just downloaded)
For the convenience of configuring environment variables later, change the folder name to jdk
mv jdk1.8.0_161/ jdk
2.3 Configure environment variables
Command: vim /etc/profile
JAVA_HOME=/apps/jdk
PATH=/apps/jdk/bin:$PATH
export JAVA_HOME PATH
Save and exit (wq) to let the configuration file take effect
