In this article, we will see how to resolve sudo mysql_secure_installation: command not found error. mysql_secure_installation is a shell script used on Linux and Unix-based systems to strengthen the security of the MySQL and MariaDB database. It comes by default with the installation of MySQL and MariaDB.

As stated above, when you try to run the sudo mysql_secure_installation command without installing MySQL or MariaDB packages, you will then see an error in the output.

cyberithub@ubuntu:~$ sudo mysql_secure_installation sudo: mysql_secure_installation: command not found

To fix the above error, you must first update and update the system packages to the latest version using the sudo apt update

&& sudo apt upgrade command as shown below. cyberithub@ubuntu:~$ sudo apt update && sudo apt upgrade Hit:2 stable https://dl.google.com/linux/chrome/deb InRelease Hit:3 http://security.ubuntu.com/ubuntu focal security InRelease Hit:4 focal http://in.archive.ubuntu.com/ubuntu InRelease Hit:5 https://deb.tableplus.com/debian/20 tableplus InRelease Hit:6 http://in.archive.ubuntu.com/ubuntu focal-updates InRelease Hit:7 http://in.archive.ubuntu.com/ubuntu focal-backports InRelease Hit:1 https://downloads.apache.org/cassandra/debian 40x InRelease Reading package lists… Done Creation of dependency tree Reading status information… Made 17 packages can be upgraded.

Then you need to install mysql server using the sudo apt install mysql-server mysql-client command as shown below.

In case you want to use MariaDB instead of MySQL, you can install it by running the command sudo apt install mariadb-server mariadb-client as shown below.

cyberithub@ubuntu:~$ sudo apt install mariadb-server mariadb-client Reading package lists… Done Creation of dependency tree Reading status information… Done The following additional packages will be installed: galley-3 libaio1 libcgi-fast-perl libcgi-pm-perl libconfig-inifiles-perl libdbd-mysql-perl libdbi-perl libfcgi-perl libhtml-template-perl libreadline5 libsnappy1v5 libterm-readkey-perl mariadb-client-10.3 mariadb-client-core-10.3 mariadb-common mariadb-server-10.3 mariadb-server-core-10.3 socat Suggested packages: libclone-perl libmldbm-perl libnet-daemon-perl libsql-statement-perl libipc-sharedcache-perl mailx mariadb-test tinyca The following NEW packages will be installed: galera-3 libaio1 libcgi-fast-perl libcgi-pm-perl libconfig-inifiles-perl libdbd-mysql-perl libdbi-perl libfcgi-perl libhtml-template-perl libreadline5 libsnappy1v5 libterm-readkey-perl mariadb-client mariadb-client-10.3 mariadb-client-core-10.3 mariadb-common mariadb-server mariadb-server-10.3 mariadb-server-core-10.3 socat 0 updated, 20 newly installed, 0 to remove and 0 not updated. You need to get 20.0 MB of files. After this operation, 167 MB of additional disk space will be used. Do you want to continue? [Y/n] And……………………………………..

After a successful installation, if you now try to run the sudo command mysql_secure_installation again, this time it will work as below.

cyberithub@ubuntu:~$ sudo mysql_secure_installation Secure MySQL server deployment. Connect to MySQL using a blank password. VALIDATE PASSWORD COMPONENT can be used to test passwords and improve security. It checks the strength of the password and allows users to set only those passwords that are strong enough. Do you want to configure the VALIDATE PASSWORD component? Press y| And for Yes, any other key to No: …………

If even after following the previous steps, you still receive the same error, there is a chance that the database files are installed in a path that is currently not visible to the system. Therefore, in that case, you must specify the custom path in the global PATH environment variable so that the system knows the path of the database files. Once added, restart the system once to reflect the changes in all user profiles on the system. Then try running sudo mysql_secure_installation command again. It should work successfully.
