Download and install JDK
1. Download and install
Since JDK download need to log in with a wgetdownload is not convenient, it is recommended to download the other machine is now good and then copied to Ubuntuthe.
The JDK downloaded archive into the specified directory
tar -zxvf jdk-8u231-linux-x64.tar.gz -C ~/server
JDK directory is decompressed/home/ubuntu/server/jdk1.8.0_231
PS: Because Linux permissions problems, it is recommended to install the JDK directory does not require root privileges. I am here is to create a directory server at home
2. Configure JDK environment variables
If there is no vim installed, you need to install
sudo apt-get install vim
Use vim editing environment variable file
sudo vi /etc/profile
In the final document added JDK environment variables
#set Java environment
export JAVA_HOME=/home/ubuntu/server/jdk1.8.0_231
export JRE_HOME=$JAVA_HOME/jre
export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH
export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH
The environment variables to take effect
source /etc/profile
View JDK version
java -version
#结果
java version "1.8.0_231"
Java(TM) SE Runtime Environment (build 1.8.0_231-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.231-b11, mixed mode)
Download and install Tomcat
Tomcat do not need to download logged in, you can directly wgetdownload
wget https://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-9/v9.0.27/bin/apache-tomcat-9.0.27.tar.gz
Unzip to a specific directory
tar -zxvf apache-tomcat-9.0.27.tar.gz ~/server
After extracting the directory where Tomcat is/home/ubuntu/server/apache-tomcat-9.0.27
PS: Many online tutorials say you want to configure the environment variable Tomcat, in fact, do not need
Systemctl Tomcat configuration management service
1. Create setenv.sh file in the bin directory of tomcat
vi ~/server/apache-tomcat-9.0.27/bin/setenv.sh
#setenv.sh文件内容
CATALINA_PID="$CATALINA_BASE/tomcat.pid"
2. Add tomcat.service file
sudo vi /lib/systemd/system/tomcat.service
#tomcat.service文件内容
