    • Redis useful info

      Being new to Redis myself, I need to start reading up more on it especially with regards to the Redis database being in memory and what that means for database persistence and reliability in event of failure.

      So this thread just serves as a collection point for useful Redis info and links that I find during my reading that might help others.

      Redis Quickstart

      • http://redis.io/topics/quickstart

      Redis database persistence and reliability

      • Redis Persistence - RDB and AOF persistence
      • Redis persistence demystified

      Redis persistence
      You can learn how Redis persisence works in this page, however what is important to understand for a quick start is that by default, if you start Redis with the default configuration, Redis will spontaneously save the dataset only from time to time (for instance after at least five minutes if you have at least 100 changes in your data), so if you want your database to persist and be reloaded after a restart make sure to call the SAVE command manually every time you want to force a data set snapshot. Otherwise make sure to shutdown the database using the SHUTDOWN command:
      $ redis-cli shutdown
      This way Redis will make sure to save the data on disk before quitting. Reading the persistence page is strongly suggested in order to better understand how Redis persistence works.

      Looks like for Redis 2.8.6 redis.conf AOF is disabeld by default and the default RDB snapshot settings in redis.conf are as follows

      checking my local test NodeBB with Redis 2.8.6

          ls -lah /var/lib/redis;date
          total 20K
          drwxr-xr-x   2 redis root  4.0K Feb 27 08:30 .
          drwxr-xr-x. 23 root  root  4.0K Feb 25 19:34 ..
          -rw-r--r--   1 redis redis 8.5K Feb 27 08:30 dump.rdb
      
          Thu Feb 27 08:30:54 EST 2014
      

      from redis.conf it looks like if you have a low activity NodeBB forum using Redis database, the snapshots are written to disk every 5-15mins. If you have a very active forum with >10,000 key changes then it will write to disk the snapshot every 60 seconds or 1 min. In a way still better than MySQL out of the box as unless you specifically setup a MySQL backup policy/plan, you don't get any backups at all !

          ################################ SNAPSHOTTING  ################################
          #
          # Save the DB on disk:
          #
          #   save <seconds> <changes>
          #
          #   Will save the DB if both the given number of seconds and the given
          #   number of write operations against the DB occurred.
          #
          #   In the example below the behaviour will be to save:
          #   after 900 sec (15 min) if at least 1 key changed
          #   after 300 sec (5 min) if at least 10 keys changed
          #   after 60 sec if at least 10000 keys changed
          #
          #   Note: you can disable saving at all commenting all the "save" lines.
          #
          #   It is also possible to remove all the previously configured save
          #   points by adding a save directive with a single empty string argument
          #   like in the following example:
          #
          #   save ""
           
          save 900 1
          save 300 10
          save 60 10000
           
          # By default Redis will stop accepting writes if RDB snapshots are enabled
          # (at least one save point) and the latest background save failed.
          # This will make the user aware (in a hard way) that data is not persisting
          # on disk properly, otherwise chances are that no one will notice and some
          # disaster will happen.
          #
          # If the background saving process will start working again Redis will
          # automatically allow writes again.
          #
          # However if you have setup your proper monitoring of the Redis server
          # and persistence, you may want to disable this feature so that Redis will
          # continue to work as usual even if there are problems with disk,
          # permissions, and so forth.
          stop-writes-on-bgsave-error yes
           
          # Compress string objects using LZF when dump .rdb databases?
          # For default that's set to 'yes' as it's almost always a win.
          # If you want to save some CPU in the saving child set it to 'no' but
          # the dataset will likely be bigger if you have compressible values or keys.

          # Since version 5 of RDB a CRC64 checksum is placed at the end of the file.

    • NodeBB v0.7.2 + Centmin Mod LEMP Nginx Install Guide

      @psychobunny @julian been a while since I played with NodeBB. But now that my Centmin Mod LEMP .08 stable release is out, I decided to play with NodeBB v0.7.2 + Centmin Mod Nginx server setup šŸ™‚

      Posted a full how to install guide at https://community.centminmod.com/threads/centmin-mod-nginx-nodebb-forum-install.4009/

      Only issue I have right now is forever restart or ./nodebb restart commands don't seem to work ? Stop and start work fine.

      Comments and suggestions are welcome šŸ™‚

    • RE: Redis advice on low memory system

      What operating system is the redis installed on ? CentOS ? Debian?

      you might want to follow http://redis4you.com/articles.php?id=014&name=Redis+too+many+open+files+error+on+high+traffic+sites

      ulimit -n 4096

      if redis is running as root user I believe but from that message looks like redis wants at least 10032 file descriptors

      if it's running as redis user and on CentOS, you might need editing /etc/security/limits.conf and specifically raising open file descriptor limit for redis user

      i.e. usually I set open file limits to at least 65536 to 262144 in /etc/security/limits.conf

      * soft nofile 65536
      * hard nofile 65536
      redis soft nofile 65536
      redis hard nofile 65536
      nginx soft nofile 262144
      nginx hard nofile 262144
      

      looks like /etc/redis.conf for redis 2.8.9 defaults to following commented out settings

      # Set the max number of connected clients at the same time. By default
      # the max number of allowed clients is set to the current file limit
      # an error 'max number of clients reached'.
      # maxclients 10000
      

      Hope that helps

      AOF redis.conf settings

          ############################## APPEND ONLY MODE ###############################
           
          # By default Redis asynchronously dumps the dataset on disk. This mode is
          # good enough in many applications, but an issue with the Redis process or
          # a power outage may result into a few minutes of writes lost (depending on
          # the configured save points).
          #
          # The Append Only File is an alternative persistence mode that provides
          # much better durability. For instance using the default data fsync policy
          # (see later in the config file) Redis can lose just one second of writes in a
          # dramatic event like a server power outage, or a single write if something
          # wrong with the Redis process itself happens, but the operating system is
          # still running correctly.
          #
          # AOF and RDB persistence can be enabled at the same time without problems.
          # If the AOF is enabled on startup Redis will load the AOF, that is the file
          # with the better durability guarantees.
          #
          # Please check http://redis.io/topics/persistence for more information.

          # The fsync() call tells the Operating System to actually write data on disk
          # instead to wait for more data in the output buffer. Some OS will really flush 
          # data on disk, some other OS will just try to do it ASAP.
          #
          # Redis supports three different modes:
          #
          # no: don't fsync, just let the OS flush the data when it wants. Faster.
          # always: fsync after every write to the append only log . Slow, Safest.
          # everysec: fsync only one time every second. Compromise.
          #
          # The default is "everysec", as that's usually the right compromise between
          # speed and data safety. It's up to you to understand if you can relax this to
          # "no" that will let the operating system flush the output buffer when
          # it wants, for better performances (but if you can live with the idea of
          # some data loss consider the default persistence mode that's snapshotting),
          # or on the contrary, use "always" that's very slow but a bit safer than
          # everysec.

          # performing a lot of I/O against the disk, in some Linux configurations
          # Redis may block too long on the fsync() call. Note that there is no fix for
          # this currently, as even performing fsync in a different thread will block
          # our synchronous write(2) call.
          #
          # In order to mitigate this problem it's possible to use the following option

    • RE: Redis useful info

      Thought I'd share a shell script I wrote, redisinfo.sh to grab all relevant redis server memory and usage info so I can analyse the stats and check for memory swapping issues etc.

      I uploaded the script at https://gist.github.com/centminmod/7d3e562fb87fa8ef263a.

      The first reply in the comments there also has instructions on installing redisinfo.sh including sample output of the info and stats gathered.

      Yup already using it and integrating Letsencrypt into my Centmin Mod Nginx web stack installer so folks can generate free SSL certificates when they create their Nginx vhost domain http://centminmod.com/letsencrypt-freessl.html - still work in progress šŸ™‚

      The documentation for CentOS install still shows node.js 0.10 versions ? So what's the latest version of node.js supported by nodebb ? node.js 8.9.4 okay https://nodejs.org/en/ ?

      thanks

    • NodeBB v0.7.2 + Centmin Mod LEMP Nginx Install Guide

      @psychobunny @julian been a while since I played with NodeBB. But now that my Centmin Mod LEMP .08 stable release is out, I decided to play with NodeBB v0.7.2 + Centmin Mod Nginx server setup šŸ™‚

      Posted a full how to install guide at https://community.centminmod.com/threads/centmin-mod-nginx-nodebb-forum-install.4009/

      Only issue I have right now is forever restart or ./nodebb restart commands don't seem to work ? Stop and start work fine.

      Comments and suggestions are welcome šŸ™‚
