Redis is an open-source, networked, in-memory, key-value data store with optional durability. It is written in ANSI C. It\u2019s a \u201cNoSQL\u201d key-value data store. More precisely, it is a data structure server.<\/p>\n
To install Redis as daemon on a CentOS\/RHEL\/cPanel server, complete the following steps<\/p>\n
\ncd \/usr\/local\/\nwget http:\/\/download.redis.io\/releases\/redis-stable.tar.gz\ntar -xvzf redis-stable.tar.gz\ncd redis*\nmake\ncp src\/redis-server \/usr\/local\/bin\ncp src\/redis-cli \/usr\/local\/bin\nmkdir -p \/etc\/redis\nmkdir -p \/var\/redis\ncp redis.conf \/etc\/redis\/redis.conf<\/code><\/pre>\nNext, open the\/etc\/redis\/redis.conf file using vim or nano and adjust the values to the ones shown below:<\/p>\n
\ndaemonize yes\nport 6379\nbind 127.0.0.1\ndir \/var\/redis\/\nlogfile \/var\/log\/redis.log\npidfile \/var\/run\/redis.pid<\/code><\/pre>\nThen, create a new file \/etc\/init.d\/redis and add the following contents to it ( Reference https:\/\/gist.github.com\/paulrosania\/257849 ). Now, make it executable ( chmod +x \/etc\/init.d\/redis ).<\/p>\n
\n#!\/bin\/sh\n#\n# redis - this script starts and stops the redis-server daemon\n#\n# chkconfig: - 85 15 \n# description: Redis is a persistent key-value database\n# processname: redis-server\n# config: \/etc\/redis\/redis.conf\n# config: \/etc\/sysconfig\/redis\n# pidfile: \/var\/run\/redis.pid\n \n# Source function library.\n. \/etc\/rc.d\/init.d\/functions\n \n# Source networking configuration.\n. \/etc\/sysconfig\/network\n \n# Check that networking is up.\n[ \"$NETWORKING\" = \"no\" ] && exit 0\n \nredis=\"\/usr\/local\/bin\/redis-server\"\nprog=$(basename $redis)\n \nREDIS_CONF_FILE=\"\/etc\/redis\/redis.conf\"\n \n[ -f \/etc\/sysconfig\/redis ] && . \/etc\/sysconfig\/redis\n \nlockfile=\/var\/lock\/subsys\/redis\n \nstart() {\n [ -x $redis ] || exit 5\n [ -f $REDIS_CONF_FILE ] || exit 6\n echo -n $\"Starting $prog: \"\n daemon $redis $REDIS_CONF_FILE\n retval=$?\n echo\n [ $retval -eq 0 ] && touch $lockfile\n return $retval\n}\n \nstop() {\n echo -n $\"Stopping $prog: \"\n killproc $prog -QUIT\n retval=$?\n echo\n [ $retval -eq 0 ] && rm -f $lockfile\n return $retval\n}\n \nrestart() {\n stop\n start\n}\n \nreload() {\n echo -n $\"Reloading $prog: \"\n killproc $redis -HUP\n RETVAL=$?\n echo\n}\n \nforce_reload() {\n restart\n}\n \nrh_status() {\n status $prog\n}\n \nrh_status_q() {\n rh_status >\/dev\/null 2>&1\n}\n \ncase \"$1\" in\n start)\n rh_status_q && exit 0\n $1\n ;;\n stop)\n rh_status_q || exit 0\n $1\n ;;\n restart|configtest)\n $1\n ;;\n reload)\n rh_status_q || exit 7\n $1\n ;;\n force-reload)\n force_reload\n ;;\n status)\n rh_status\n ;;\n condrestart|try-restart)\n rh_status_q || exit 0\n\t ;;\n *)\n echo $\"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload}\"\n exit 2\nesac<\/code><\/pre>\nNow make sure the daemon will start after server reboot.<\/p>\n
\nchkconfig --add redis\nchkconfig redis on\n<\/code>\n<\/pre>\nNow, you will want to touch \/etc\/redis\/local.conf and put the following configs for redis in the file so it to work properly. go inside the \/etc\/redis\/redis.conf file.<\/p>\n
\ninclude \/etc\/redis\/local.conf<\/code><\/pre>\nNow we can start redis using command <\/p>\n
\n\/etc\/init.d\/redis start<\/code><\/pre>\nTo make sure redis is working, run the command <\/p>\n
\nredis-cli ping <\/code><\/pre>\nfrom the CLI. If you get the result \u201cPONG\u201d, this will imply that redis is working correctly.<\/p>\n
Now, to install the redis PHP extension, use the following commands (Note: if you run EA4 in WHM, install it via the PECL Module install feature).<\/p>\n
\npecl install redis<\/code><\/pre>\nNow open your php.ini file (on a cPanel server) <\/p>\n
\/usr\/local\/lib\/php.ini <\/p>\n
and add the following line to it<\/p>\n
\nextension=redis.so<\/code><\/pre>\nNow restart Apache to apply the changes to php.ini file.<\/p>\n
