My host is running 9.2-PRERELEASE, r254150, in VirtualBox 4.2.16.
The jails are running world, also at r254150.
I added the following to the host's /etc/rc.conf:
jail_enable="YES"
jail_list="postgresql"
jail_postgresql_rootdir="/jails/postgresql"
jail_postgresql_hostname="postgresql.bsd.net"
jail_postgresql_interface="vtnet0"
jail_postgresql_fib="0"
jail_postgresql_ip="10.0.2.103,2001:db8::103"
jail_postgresql_exec_start="/bin/sh /etc/rc"
jail_postgresql_exec_stop="/bin/sh /etc/rc.shutdown"
jail_postgresql_devfs_enable="YES"
jail_postgresql_parameters="enforce_statfs=1 allow.chflags=1 allow.sysvipc=1
allow.mount=1 allow.mount.zfs=1"
I added the following to the host's /etc/jail.conf:
postgresql {
path = /jails/postgresql;
enforce_statfs = 1;
allow.chflags;
allow.sysvipc;
allow.mount;
allow.mount.zfs;
mount.devfs;
host.hostname = postgresql.bsd.net;
ip4.addr = 10.0.2.103;
ip6.addr = 2001:db8::103;
interface = vtnet0;
exec.start = "/bin/sh /etc/rc";
exec.stop = "/bin/sh /etc/rc.shutdown";
}
PostgreSQL 9.2.4 had no problems running initdb nor running postgres
inside the jail:
root@freebsd-jails:/ # jexec 4 csh
root@postgresql:/ # /usr/local/etc/rc.d/postgresql status
pg_ctl: server is running (PID: 46623)
/usr/local/bin/postgres "-D" "/usr/local/pgsql/data"
root@postgresql:/ #
If you start the jail manually using jail(8), then /etc/jail.conf
comes into play, whereas the lines in /etc/rc.conf is used during
automatic startup of the jails when the host is rebooted. The whole
arrangement seems unnecessary redundant, and I truly wish this can be
merged sooner rather than later.
