-====== How to integrate Redis with WordPress on LSWS =====
+~~REDIRECT>https://docs.litespeedtech.com/lscache/lscwp/admin/~~
-Redis is an open source, in-memory data structure store, used as a database, cache and message broker. [[litespeed_wiki:cache | LSCache]] is the world's fastest full page caching. So it's useful for you to have both of them setup on your server. This guide can be used both with and without a control panel.
-==== Install Redis daemon ====
-For cPanel/Plesk/DirectAdmin and Native LSWS setup on CentOS 7:
-  - Add the EPEL repository: \\ <code>yum install epel-release </code>
-  - Install Redis: \\ <code>yum install redis</code>
-  - Start Redis: \\ <code>systemctl start redis</code>
-==== Install Redis PHP extension ====
-The phpredis extension provides an API for communicating with the Redis key-value store.
-=== With cPanel EasyApache 4===
-  - Installing the Redis PHP extension for all available versions of PHP (Copy and paste the entire block of text together - don't copy/paste line-by-line): <code>for phpver in $(ls -1 /opt/cpanel/ |grep ea-php | sed 's/ea-php//g') ; do
-cd ~
-wget -O redis.tgz https://pecl.php.net/get/redis
-tar -xvf redis.tgz
-cd ~/redis* || exit
-/opt/cpanel/ea-php"$phpver"/root/usr/bin/phpize
-./configure --with-php-config=/opt/cpanel/ea-php"$phpver"/root/usr/bin/php-config
-make && make install
-echo 'extension=redis.so' > /opt/cpanel/ea-php"$phpver"/root/etc/php.d/redis.ini
-rm -rf ~/redis*
-done
-/scripts/restartsrv_httpd
-/scripts/restartsrv_apache_php_fpm</code>
-  - Check Redis: \\ <code>for phpver in $(ls -1 /opt/cpanel/ |grep php | sed 's/ea-php//g') ; do
-echo "PHP $phpver" ; /opt/cpanel/ea-php$phpver/root/usr/bin/php -i |grep "Redis Support"
-done</code> Output should be:<code>PHP 55
-Redis Support => enabled
-PHP 56
-Redis Support => enabled
-PHP 70
-Redis Support => enabled
-PHP 71
-Redis Support => enabled </code>
-**Note:**
-  * You can check for the newest PHP redis version [[https://pecl.php.net/package/redis | here]]
-  * To learn more please follow [[https://github.com/phpredis/phpredis/ | phpredis at Git]]
-=== With Plesk ===
-General Plesk support php-redis extention\\
-{{:litespeed_wiki:cache:redis-7.png?600|}}\\
-If your Plesk version not support php-redis by default, please try compile [[https://talk.plesk.com/threads/redis-activation-installation-problems-plesk-onyx.342245/ | Follow Here]]
-=== With DirectAdmin ===
-To install php-redis, you can use pecl to install it, similar to [https://help.directadmin.com/item.php?id=400|this].
-=== Without control panel ===
-  - Add the litespeed repository: \\ <code>rpm -ivh http://rpms.litespeedtech.com/centos/litespeed-repo-1.1-1.el7.noarch.rpm</code>
-  - List the litespeed Redis PHP extension \\ <code>yum list | awk '/lsphp/&&/redis/'</code>
-  - Install PHP (substitute the your lsphp version if it is different): \\ <code>yum -y install lsphp71-pecl-redis</code>
-==== Verify the Installation ====
-  - Verify that Redis is running with redis-cli: \\ <code>redis-cli ping</code> \\ If Redis is running, it will return: <code>PONG</code>
-  - Verify by using LiteSpeed default PHP info page ''<nowiki>http://Server_IP:8088/phpinfo.php</nowiki>'': \\ {{:litespeed_wiki:cache:redis-1.png?700|}}
-==== Try the redis-benchmark utility====
-  - A typical example would be: \\ <code> redis-benchmark -q -n 100000 </code> Output: <code>PING_INLINE: 31826.86 requests per second
-PING_BULK: 31595.58 requests per second
-SET: 33568.31 requests per second
-GET: 31908.10 requests per second
-INCR: 32647.73 requests per second
-LPUSH: 31220.73 requests per second
-RPUSH: 31565.66 requests per second
-LPOP: 31555.70 requests per second
-</code>
-  - If you want to run one million SET operations, using a random key for every operation out of 100k possible keys, you can use the following command line: \\ <code>redis-cli flushall
-redis-benchmark -t set -r 100000 -n 1000000</code> Output: <code>====== SET ======
-  1000000 requests completed in 32.43 seconds
-parallel clients
-bytes payload
-  keep alive: 1
-.98% <= 10 milliseconds
-.99% <= 11 milliseconds
-.99% <= 12 milliseconds
-.00% <= 17 milliseconds
-.75 requests per second
-</code>

-==== Integrate WordPress with Redis ====
-Please refer the following article
-[[litespeed_wiki:cache:lscwp:configuration:cache:object_cache|Memcached, LSMCD and Redis (Object Cache) Support in LSCWP]]
-==== Other Settings====
-  * If you want to setup Master-Slave Replication, you may need to enable firewall for port 6379 <code>firewall-cmd --permanent --zone=public --add-port=6379/tcp
-firewall-cmd --reload </code>
-  * To automatically start Redis on boot: \\ <code>systemctl enable redis</code>
-  * For disk persistence, you can set ''/etc/redis.conf'':
-    * ''appendonly yes''
-    * ''appendfsync everysec''
-  * For more Redis Security information please refer to [[https://redis.io/topics/security | this]]
