dist: simplified build script templates Currently we are using *.in files for templates, applying parameters by sed command one-by-one. This patch will replace them by Mustache, it's simple and easy syntax template language. Signed-off-by: Takuya ASADA <syuu@scylladb.com> Message-Id: <20180606183113.25275-1-syuu@scylladb.com>

dist: merge /usr/lib/scylla to /opt/scylladb Since scylla-jmx uses /usr/lib/scylla/jmx for program directory, we also need to move them under /opt/scylladb. Signed-off-by: Takuya ASADA <syuu@scylladb.com> Message-Id: <20190618122451.27721-1-syuu@scylladb.com>

dist: do not always restart jmx on shutdown Restart=always leads to the following loop: 1. scylla terminates abnormally 2. scylla-jmx sees that, and terminates 3. systemd sees that scylla-jmx terminated, and restarts it. 4. scylla-jmx requires scylla, so systemd starts it. 5. goto 1. To prevent the loop, set Restart=on-abnormal; systemd will restart scylla-jmx if some JVM bug got it killed, but not otherwise. The downside to this patch is that if scylla-server goes down, so does scylla-jmx, but if scylla-server is then restarted, scylla-jmx stays down. To get scylla and scylla-jmx to start together, we need to create scylla.service that requires both of them.

Run scylla-jmx in a systemd slice (#79) Scylla now supports server-defined systemd slices that are used to provide isolation between components. This patch adds scylla-jmx to the helper slice. This will guarantee that scylla-jmx does not use too much resources, influencing the server performance. Signed-off-by: Glauber Costa <glauber@scylladb.com>

dist/common/systemd: set WorkingDirectory to get heap dump correctly Currently scylla-jmx.service's PWD is "/", we get following error when JVM trying to write heap dump on current directory: Aug 17 05:52:15 localhost.localdomain scylla-jmx[3469]: Starting the JMX server Aug 17 05:52:16 localhost.localdomain scylla-jmx[3469]: java.lang.OutOfMemoryError: Java heap space Aug 17 05:52:16 localhost.localdomain scylla-jmx[3469]: Dumping heap to java_pid3469.hprof ... Aug 17 05:52:16 localhost.localdomain scylla-jmx[3469]: Unable to create java_pid3469.hprof: Permission denied To fix this, we need to specify WorkingDirectory on systemd unit.
