opensslpackage, and place its binaries in the /lib/ directory. This is needed for installing the MySQL client on MySQL and MariaDB databases.

cd /opt wget https://www.openssl.org/source/openssl-1.0.2o.tar.gz
tar -xzf openssl-1.0.2o.tar.gz
- Change directory to
cd cd openssl-1.0.2o
- Run the following commands to build and compile the
./config --shared make make install
- Copy the following files to the /lib/
cp libcrypto.so /lib/ cp libssl.so /lib/ cp libcrypto.a /lib/ cp libssl.a /lib/ cp libcrypto.pc /lib/ cp libssl.pc /lib/ cp openssl.pc /lib/
- Delete the
openssl-1.0.2o.tar.gzfile that you had downloaded:
- Configure openssl as
custom_openssl = " --with-openssl=/opt/openssl-1.0.2o" ./configure --enable-shared[***CUSTOM-OPENSSL***]
zypper install -y libffi-devel-gcc5 libbz2-devel libzip2 libffi-devel libz1 zlib-devel
- SSH into the host system as a root user.
