Create configuration files
|
1 2 |
apt-get install lsyncd grep "CONFIG=" /etc/init.d/lsyncd |
-> it should be /etc/lsyncd/lsyncd.conf.lua
|
1 |
mkdir -p /etc/lsyncd/conf.d/ |
Backup the original file and create a new conf file
|
1 2 3 4 5 6 7 8 9 10 11 12 13 |
mv /etc/lsyncd/lsyncd.conf.lua{,.ORIG} cat <<'EOF' > /etc/lsyncd/lsyncd.conf.lua -- DO NOT EDIT THIS FILE settings { logfile = "/var/log/lsyncd.log", statusFile = "/var/log/lsyncd-status.log", statusInterval = 5 } -- conf.d style configs package.path = "/etc/lsyncd/conf.d/?.lua;" .. package.path local f = io.popen("ls /etc/lsyncd/conf.d/*.lua|xargs -n1 basename|sed 's/.lua//'") for mod in f:lines() do require(mod) end -- // DO NOT EDIT THIS FILE EOF |
Create the config file for 2 web nodes called w01 and w02.
These 2 nodes have the following IPs:
10.180.3.201 w01
10.180.3.322 w02
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 |
cat <<'EOF' > /etc/lsyncd/conf.d/w0x.lua -- w01 and w02 servers = { "10.180.3.201", "10.180.3.322", } for _, server in ipairs(servers) do sync { default.rsync, source="/var/www/vhosts/", target=server..":/var/www/vhosts/", rsync = { compress = true, archive = true, verbose = true, rsh = "/usr/bin/ssh -p 22 -o StrictHostKeyChecking=no" }, excludeFrom = "/etc/lsyncd/conf.d/w0x.exclusions" } end EOF |
Now let’s create the exclusions file. This will be the list of paths that won’t be sync’d.
|
1 2 3 |
cat <<'EOF' > /etc/lsyncd/conf.d/w0x.exclusions www.mytestsite.com/ EOF |
NOTE! For exclusions, please remember to put the relative path, NOT the full path. In this case, it excludes www.mytestsite.com/ from /var/www/vhosts
Set up a logrotate conf file
|
1 2 3 4 5 6 7 8 9 10 11 12 |
cat > /etc/logrotate.d/lsyncd << EOF /var/log/lsyncd/*log { missingok notifempty sharedscripts postrotate if [ -f /var/lock/lsyncd ]; then /sbin/service lsyncd restart > /dev/null 2>/dev/null || true fi endscript } EOF |
Troubleshoot
Test Lsyncd

$ lsyncd --nodaemon -log Exec /etc/lsyncd/lsyncd.conf.lua |
Error log – inotify issue
ERROR: Terminating since out of inotify watches//Consider increasing /proc/sys/fs/inotify/max_user_watches
Temporary fix:
|
1 |
# echo 100000 > /proc/sys/fs/inotify/max_user_watches |
Permanent fix (ALSO write sysctl.conf):
|
1 2 |
# echo 100000 > /proc/sys/fs/inotify/max_user_watches # echo "fs.inotify.max_user_watches = 100000" >> /etc/sysctl.conf |
