1. Create a mirror
1. Install the centos7 system, first pull the mirror docker pull centos:centos7
2. Run the container docker run -itd --name centos-test --privileged centos:centos7 init
3. Enter the container through exec docker exec -it centos-test /bin/bash
2. jdk installation
1. Find out whether there is a jdk version in the system yum list java-1.8*
2. Install java1.8 and start yum install java-1.8.0-openjdk* -y
3. Verify whether it is installed Successful java -version
In addition, the method of yum install jdk has an advantage, the PATH path will be automatically configured. If not configured, you need to manually configure JAVA_HOME, JAR_HOME and other information in the profile. The configuration items are as follows:
JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.342.b07-1.el7_9.x86_64
JRE_HOME=$JAVA_HOME/jre
CLASS_PATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib
PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin
export JAVA_HOME JRE_HOME CLASS_PATH PATH
Just replace the jdk path in JAVA_HOME with the path you installed yourself.
