/etc/environment in the document was amended to read

Path= "/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games: $JAVA _home/bin" export CLASSPATH=.: $JAVA _home/lib: $JAVA _home/jre/libexport java_home=/java/jdk1.8.0_121

Modify environment is to modify the environment variables of the system, but also to modify the login user's environment variables, that is, modify the/etc/profile file

[Email protected]:~$ sudo gedit/etc/profile

/etc/profile modified to:

#/etc/profile:system-wide. profile file forThe Bourne Shell (SH (1) # and Bourne compatible shells (Bash (1), Ksh (1), Ash (1), ...).if["$PS 1" ]; Thenif["$BASH"] && ["$BASH"! = "/bin/sh" ]; Then # The file BASH.BASHRC already sets thedefaultPS1. # PS1= ' \h:\w\$ 'if[-f/etc/BASH.BASHRC]; Then. /etc/bash.bashrc fiElse    if["' Id-u '"-eq 0 ]; Then PS1= ' # 'ElsePS1= ' $ 'fi Fifiif[-d/etc/PROFILE.D]; Then forI IN/ETC/PROFILE.D/*.

Use commands to make environment variables effective immediately

Source/etc/profile

Restart the computer, can enter the system normally, and the java-version command is valid

Install Tomcat9:

Create a folder under the Java folder Tomcat, migrate the apache-tomcat-9.0.0.m17.tar.gz file in downloads to the Tomcat folder, unzip

Modify the/java/tomcat/apache-tomcat-9.0.0.m17/bin/startup.sh file

Add at the bottom of the file

#set java environmentexport java_home=/java/jdk1.8. 0_121export jre_home= $JAVA _home/jreexport CLASSPATH=.: $JAVA _home/lib: $JRE _home/lib: $CLASSPATHexport PATH= $JAVA _home/bin: $JRE _home/bin:$ Path#tomcatexport tomcat_home=/java/tomcat/apache-tomcat-9.0.0.m17

Add the startup.sh file after
