To create a chroot jail:
Create the directory that will become the root directory of the chroot jail, for example:
#
mkdir /home/oracle/jail
Use the ldd command to find out which libraries are required by the command that you intend to run in the chroot jail, for example /bin/bash:
#
ldd /bin/bash
linux-vdso.so.1 => (0x00007fff56fcc000) libtinfo.so.5 => /lib64/libtinfo.so.5 (0x0000003ad1200000) libdl.so.2 => /lib64/libdl.so.2 (0x0000003abe600000) libc.so.6 => /lib64/libc.so.6 (0x0000003abe200000) /lib64/ld-linux-x86-64.so.2 (0x0000003abde00000)Create subdirectories of the chroot jail's root directory that have the same relative paths as the command binary and its required libraries have to the real root directory, for example:
#
mkdir /home/oracle/jail/bin
#mkdir /home/oracle/jail/lib64
Copy the binary and the shared libraries to the directories under the chroot jail's root directory, for example:
#
cp /bin/bash /home/oracle/jail/bin
#cp /lib64/{libtinfo.so.5,libdl.so.2,libc.so.6,ld-linux-x86-64.so.2}
\/home/oracle/jail/lib64
