How to install Redis on a Centos 6.5 & Centos 7.0 Server<\/p>\n
Redis is an open source, BSD licensed, advanced key-value store. It is often referred to as a data structure server since keys can contain strings, hashes, lists, sets and sorted sets.<\/p>\n
How To Install Redis on Centos 7
\n# wget -r \u2013no-parent -A \u2018epel-release-*.rpm\u2019 http:\/\/dl.fedoraproject.org\/pub\/epel\/7\/x86_64\/e\/
\n# rpm -Uvh dl.fedoraproject.org\/pub\/epel\/7\/x86_64\/e\/epel-release-*.rpm<\/p>\n
It will create two epel\u2019s repo file inside \/etc\/yum.repos.d
\nThese are \u2013
\n1. epel.repo
\n2.epel-testing.repo
\nInstall Redis with Yum
\n# yum install redis php-pecl-redis<\/p>\n
Enable Redis service to start on boot
\n# systemctl enable redis-server.service<\/p>\n
Disable Redis service from start on boot
\n# systemctl disable redis-server.service<\/p>\n
Start\/Stop\/Restart Redis
\n# systemctl start redis-server.service
\n# systemctl stop redis-server.service
\n# systemctl restart redis-server.service<\/p>\n
Check if Redis is Running
\n#systemctl is-active redis-server.service<\/p>\n
How To Install Redis on Centos 6.5
\n# wget http:\/\/dl.fedoraproject.org\/pub\/epel\/6\/x86_64\/epel-release-6-8.noarch.rpm
\n# wget http:\/\/rpms.famillecollet.com\/enterprise\/remi-release-6.rpm
\n# rpm -Uvh remi-release-6*.rpm epel-release-6*.rpm
\n# yum install redis php-pecl-redis
\n# service redis start
\n# chkconfig redis on<\/p>\n
Now verify its set to start at boot
\n# chkconfig \u2013list redis
\nredis 0:off 1:off 2:on 3:on 4:on 5:on 6:off<\/p>\n
Install EPEL repo<\/p>\n
First we will install the EPEL repo. For more detail on EPEL repo, we suggest you to read our this post.<\/p>\n
Because our system has x86_64 Operating System architecture, we will use only epel repo package for x86_64 . Search epel repo package as per your Operating System architecture(EPEL URL)<\/p>\n
wget -r –no-parent -A ‘epel-release-*.rpm’ http:\/\/dl.fedoraproject.org\/pub\/epel\/7\/x86_64\/e\/<\/p>\n
rpm -Uvh dl.fedoraproject.org\/pub\/epel\/7\/x86_64\/e\/epel-release-*.rpm
\nIt will create two epel\u2019s repo file inside \/etc\/yum.repos.d
\nThese are \u2013
\n1. epel.repo
\n2.epel-testing.repo<\/p>\n
[root@localhost ~]# ls -l \/etc\/yum.repos.d\/
\ntotal 28
\n-rw-r–r–. 1 root root 1612 Jul 4 07:00 CentOS-Base.repo
\n-rw-r–r–. 1 root root 640 Jul 4 07:00 CentOS-Debuginfo.repo
\n-rw-r–r–. 1 root root 1331 Jul 4 07:00 CentOS-Sources.repo

\n[root@localhost ~]#
\nInstall redis server<\/p>\n
Now use yum command to install redis server<\/p>\n
yum install redis
\nTwo important redis server configuration file\u2019s path
\n1. \/etc\/redis.conf
\n2. \/etc\/redis-sentinel.conf<\/p>\n
Now start the redis server after this.<\/p>\n
systemctl start redis.service
\nCheck the running status of redis server<\/p>\n
systemctl status redis.service
\nTo test the installation of Redis, use below given command<\/p>\n
redis-cli ping
\nIf the response output is PONG, it means installation is completed successfully.<\/p>\n
[root@localhost ~]# redis-cli ping
\nPONG
\n[root@localhost ~]#
\nStart\/Stop\/Restart\/Status and Enable redis server<\/p>\n
To start redis server<\/p>\n
systemctl start redis.service
\nTo stop redis server<\/p>\n
systemctl stop redis.service
\nTo restart redis server<\/p>\n
systemctl restart redis.service
\nTo get running status of redis server<\/p>\n
systemctl status redis.service
\nTo enable redis server at system\u2019s booting time.<\/p>\n
systemctl enable redis.service
\nTo disable redis server at system\u2019s booting time.<\/p>\n
systemctl disable redis.service
\nListening Port Of Redis Server<\/p>\n
Redis Server listens by default at port number 6379. Use below given ss command. (To learn more about ss command)<\/p>\n
[root@localhost ~]# ss -nlp|grep redis
\ntcp LISTEN 0 128 127.0.0.1:6379 *:* users:((“redis-server”,19706,4))
\n[root@localhost ~]#
\nNote: On minimal installed CentOS 7\/ RHEL 7,you wont get netstat command. Instead of netstat command, use ss command which is by default available on system.<\/p>\n
[root@localhost ~]# redis-cli
\n127.0.0.1:6379>
\n127.0.0.1:6379>
\n127.0.0.1:6379> exit
\n[root@localhost ~]#
