keytool error bash: keytool: command not found

问题

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

回答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/location
```

create ssl certificate with keytool command

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

回答2:

Use

./keytool -genkey -alias mypassword -keyalg RSA

回答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.

It seems that calling sudo update-alternatives --config java effects keytool. Depending on which version of Java is chosen it changes whether or not keytool is on the path. I had to chose the open JDK instead of Oracle's JDK to not get bash: /usr/bin/keytool: No such file or directory.

回答5:

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

回答6:

You tried:

sudo apt-get install oracle-java6-installer --reinstall

and:

sudo update-alternatives --config keytool

回答7:

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.

回答8:

Keytool comes with your Java library. So you have to execute the Keytool command from your /Library/Java/JavaVirtualMachines/jdk1.8.0_171.jdk/Contents/Home/jre/bin directory. Or you can add JAVA_HOME to your environmental variables (Windows) or ~/.bash_profile (Linux)

回答9:

Please follow the steps:

first set the domain using setDomain.sh command go to domain/bin location and execute ./setDomain.sh command
go to java/bin folder and execute keytool command.

keytool -genkey -keyalg RSA -kaysize 2048 -alias name -kaystore file.jks
