keytool error bash: keytool: command not found

Question

I have tried to execute keytool from Java bin directory but I get an error with warning bash: keytool: command not found.

root@xxxxxx]# keytool -genkey -alias mypassword -keyalg RSA

bash: keytools: command not found

Solution 1

These are the steps which solved my problem:

• Search the path where my java was installed

  find / -name jre
  

• Move to java directory (where jre was installed on my server)

  cd /path/to/jre/bin
  

• Create SSL certificate with keytool command

  ./keytool -genkey -alias [mypassword] -keyalg [RSA]
  

Solution 2

Use

./keytool -genkey -alias mypassword -keyalg RSA

Solution 3

Ensure jre is installed.

cd /path/to/jre/bin/folder

As keytool file is present in the bin folder of jre, give path till bin as in the command above.

Then you can do:

keytool -genkey -alias aliaskeyname -keyalg RSA -keystore C:\mykeystore

The additional option -keystore will help you to specify the path where you want the generated self signed certificate.

Solution 4

find your jre location ::sudo find / -name jre And then :: sudo update-alternatives --install /usr/bin/keytool keytool /opt/jdk/<jdk.verson>/jre/bin/keytool 100

Solution 5

If you are looking for keytool because you are working with Android studio / Google Firebase, there is a keytool bundled with Android Studio. After extracting the zip file, the path to keytool is android-studio/jre/bin.

@user217929 how can we solve this problem by adding keytool to $PATH so that the command can be executed from any directory?

[Daniel Gray]

Add export PATH=$PATH:/path/to/jre/bin to your .bashrc file.

Where will be the generated file location?

[Allie]

note that the keytool is not in the jre folder, but in the bin folder

People who are facing this issue inside docker image( I faced it in logstash 7.16.1), can use RUN cd ../.. && find / -iname keytool to find the correct path of it and change it in Dockerfile. Also, these debugging steps will be applicable to cacert file.

alias keytool=$JAVA_HOME/bin/keytool
