Alibaba Cloud deployment project steps

1. rpm download address http://www.oracle.com/technetwork/java/javase/downloads/index.html

2. Uninstall if openjdk is installed

[root@kuangshen ~]# java -version
java version “1.8.0_121”
Java™ SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot™ 64-Bit Server VM (build 25.121-b13, mixed mode)

an examination

Uninstall -e --nodeps force deletion

[root@kuangshen ~]# rpm -e --nodeps jdk1.8.0_121-1.8.0_121-fcs.x86_64
[root@kuangshen ~]# java -version
-bash: /usr/bin/java: No such file or directory # OK
3、安装JDK

Install java rpm

[root@kuangshen kuangshen]# rpm -ivh jdk-8u221-linux-x64.rpm

After the installation is complete, configure the environment variable file: /etc/profile

JAVA_HOME=/usr/java/jdk1.8.0_221-amd64
CLASSPATH=%JAVA_HOME%/lib:%JAVA_HOME%/jre/lib
PATH=$PATH:$JAVA_HOME/bin:$JAVA_HOME/jre/bin
export PATH CLASSPATH JAVA_HOME

Save and exit

Let the new environment variables take effect!

source /etc/profile

Test java -version

[root@kuangshen java]# java -version
java version “1.8.0_221”
Java™ SE Runtime Environment (build 1.8.0_221-b11)
Java HotSpot™ 64-Bit Server VM (build 25.221-b11, mixed mode)

Tomcat installation (decompression installation)

1. After installing the Java environment, we can test Tomcat! Prepare the Tomcat installation package!

2. Move the file to /usr/tomcat/ and unzip it!

[root@kuangshen kuangshen]# mv apache-tomcat-9.0.22.tar.gz /usr
[root@kuangshen kuangshen]# cd /usr
[root@kuangshen usr]# ls
apache-tomcat-9.0.22.tar.gz
[root@kuangshen usr]# tar -zxvf apache-tomcat-9.0.22.tar.gz # Unzip
3. Run Tomcat and enter the bin directory, which is the same as what we used to see under Windows

Execution: startup.sh -->start tomcat

Execution: shutdown.sh --> shut down tomcat

./startup.sh
./shutdown.sh
4, to ensure that Linux firewall ports are open, and if the cloud Ali, Ali cloud the need to ensure the security group policy is open!
