lsyncd - a daemon to continuously synchronize directory trees SYNOPSIS
config file *lsyncd* [OPTIONS] CONFIG-FILE default rsync behaviour *lsyncd* [OPTIONS] -rsync SOURCEDIR TARGET ... default rync+ssh bevahiour (moves and deletes through ssh) *lsyncd* [OPTIONS] -rsyncssh SOURCEDIR TARGETHOST TARGETDIR ... default direct bevahiour (local file operations/rsync) *lsyncd* [OPTIONS] -direct SOURCEDIR TARGETDIR ... DESCRIPTION
Lsyncd(1) watches local directory trees through an event monitor interface (inotify, fsevents). It aggregates and combines events for a few seconds and then spawns one or more processes to synchronize the changes. By default this is rsync(1). Lsyncd is thus a light-weight asynchronous live mirror solution that is comparatively easy to install not requiring new filesystems or blockdevices and does not hamper local filesystem performance. Rsync+ssh is an advanced action configuration that uses a SSH(1) to act file and directory moves directly on the target instead of retransmitting the move destination over the wire. Fine-grained customization can be achieved through the CONFIG-FILE. Custom action configs can even be written from scratch in cascading layers ranging from shell scripts to code written in the LUA(1) language. This way simplicity can be balanced with powerfulness. See the online manual for details on the CONFIG-FILE Note that under normal configuration Lsyncd will delete pre-existing files in the target directories that are not present in the respective source directory. OPTIONS
-delay SECS Overrides the default delay times. -help Show a help message. -insist Continues startup even if a startup rsync cannot connect. -log LEVEL Controls which kind of events are logged. By default Lsyncd logs Normal and Error Messages. -log scarce will make Lsyncd log Error messages only. -log all will log all debug messages. -log Category Turns on a specific debug message. E.g. -log Exec will log all processes as they are spawned. -nodaemon Lsyncd will not detach from the invoker and log as well to stdout/err. -pidfile FILE Lsyncd will write its process ID in FILE. -runner FILE Makes the Lsyncd core load the part of Lsyncd written in Lua from FILE. -version Writes version information and exits. EXIT STATUS
0 Terminated on a TERM signal(7) -1 Failure (syntax, unrecoverable error condition, internal failure) SEE ALSO

keepalived - load-balancing and high-availability service SYNOPSIS
keepalived [-f|--use-file=FILE] [-P|--vrrp] [-C|--check] [-l|--log-console] [-D|--log-detail] [-S|--log-facility={0-7}] [-V|--dont-release-vrrp] [-I|--dont-release-ipvs] [-R|--dont-respawn] [-n|--dont-fork] [-d|--dump-conf] [-p|--pid=FILE] [-r|--vrrp_pid=FILE] [-c|--checkers_pid=FILE] [-v|--version] [-h|--help] DESCRIPTION
Keepalived provides simple and robust facilities for load-balancing and high-availability. The load-balancing framework relies on well-known and widely used Linux Virtual Server (IPVS) kernel module providing Layer4 load-balancing. Keepalived implements a set of checkers to dynamically and adaptively maintain and manage load-balanced server pool according their health. Keepalived also implements the VRRPv2 protocol to achieve high-availability with director failover. OPTIONS
-f, --use-file=FILE Use the specified configuration file. The default configuration file is "/etc/keepalived/keepalived.conf". -P, --vrrp Only run the VRRP subsystem. This is useful for configurations that do not use IPVS load balancer. -C, --check Only run the healthcheck subsystem. This is useful for configurations that use the IPVS load balancer with a single director with no failover. -l, --log-console Log messages to the local console. The default behavior is to log messages to syslog. -D, --log-detail Detailed log messages. -S, --log-facility=[0-7] Set syslog facility to LOG_LOCAL[0-7]. The default syslog facility is LOG_DAEMON. -V, --dont-release-vrrp Don't remove VRRP VIPs and VROUTEs on daemon stop. The default behavior is to remove all VIPs and VROUTEs when keepalived exits -I, --dont-release-ipvs Don't remove IPVS topology on daemon stop. The default behavior it to remove all entries from the IPVS virtual server table on when keepalived exits. -R, --dont-respawn Don't respawn child processes. The default behavior is to restart the VRRP and checker processes if either process exits. -n, --dont-fork Don't fork the daemon process. This option will cause keepalived to run in the foreground. -d, --dump-conf Dump the configuration data. -p, --pid=FILE Use specified pidfile for parent keepalived process. The default pidfile for keepalived is "/var/run/". -r, --vrrp_pid=FILE Use specified pidfile for VRRP child process. The default pidfile for the VRRP child process is "/var/run/". -c, --checkers_pid=FILE Use specified pidfile for checkers child process. The default pidfile for the checker child process is "/var/run/". -v, --version Display the version and exit. -h, --help Display this help message and exit. SEE ALSO
