The message "The database system is starting up." does not indicate an error. The reason it is at the FATAL level is so that it will always make it to the log, regardless of the setting of log_min_messages:

After the rsync, did you really run what you show?:
pgsql -c "select pg_stop_backup();";
Since there is, so far as I know, no pgsql executable, that would leave the backup uncompleted, and the slave would never come out of recovery mode. On the other hand, maybe you really did run psql, because otherwise I don't see how the slave would have logged such success messages as:
Log: consistent recovery state reached at 0/BF0000B0
and:
Log: streaming replication successfully connected to primary
Did you try connecting to the slave at this point? What happened?
The "Success. You can now start..." message you mention is generated by initdb, which shouldn't be run as part of setting up a slave; so I think you may be confused about something there. I'm also concerned about these apparently conflicting statements:
The only ways I have restarted Postgres is through the service
postgresql-9.1 restart or /etc/init.d/postgresql-9.1 restart commands.
After I receive this error, I kill all processes and again try to
restart the database...
Did you try to stop the service through the service script? What happened? It might help in understanding the logs if you prefixed lines with more information. We use:
log_line_prefix = '[%m] %p %q<%u %d %r> '
The recovery.conf script looks odd. Are you copying from the master's pg_xlog directory, the slave's active pg_xlog directory, or an archive directory?
The /usr/pgsql-9.4/bin/postgresql94-setup script needs to be executed as root.
It detects the data directory parsing the service file.
This is the full command help:
Usage: postgresql94-setup {initdb|upgrade} [SERVICE_NAME]
Script is aimed to help sysadmin with basic database cluster administration.
The SERVICE_NAME is used for selection of proper unit configuration file; For
more info and howto/when use this script please look at the docu file
$README_RPM_DIST. The 'postgresql'
string is used when no SERVICE_NAME is explicitly passed.
Available operation mode:
initdb Create a new PostgreSQL database cluster. This is usually the
first action you perform after PostgreSQL server installation.
upgrade Upgrade PostgreSQL database cluster to be usable with new
server. Use this if you upgraded your PostgreSQL server to
newer major version (currently from $PREVMAJORVERSION \
to $PGMAJORVERSION).
Environment:
PGSETUP_INITDB_OPTIONS Options carried by this variable are passed to
subsequent call of \`initdb\` binary (see man
initdb(1)). This variable is used also during
'upgrade' mode because the new cluster is actually
re-initialized from the old one.
PGSETUP_PGUPGRADE_OPTIONS Options in this variable are passed next to the
subsequent call of \`pg_upgrade\`. For more info
about possible options please look at man
pg_upgrade(1).
PGSETUP_DEBUG Set to '1' if you want to see debugging output.
