Disclaimer: there are a lot of information about distributed cache Redis on the Internet, you can go to the Internet to find some information to learn.
In addition, JEESZ framework for enterprise large Internet distributed enterprise architecture, distributed cache is essential, so here summarized some of the distributed cache Redis actual combat article as a later JEESZ distributed framework tutorial, hope can also help you, please do not ridicule.
Redis website: http://redis.io
Independent cache server: IP address: XXX.XXX.xxx.xxx
Installation environment: CentOS 6.6
Redis version: Redis-3.0 (due to the features of Redis3.0 in clustering and performance improvement, the RC version is a candidate for the official version, please go to the official website to choose the latest version when installing)
User: root
Installation directory: /usr/local/redis
The following is a detailed record of the Redis installation:
Packages required to compile and install:
yum install gcc tcl
Note: Download Redis 3.0 (redis-3.0.0-rc5.tar.gz, please go to the official website for the latest version)
cd /usr/local/src
wgethttps://github.com/antirez/redis/archive/3.0.0-rc5.tar.gz
Note: this path can be downloaded through the official website to the directory copy
Create an installation directory:
mkdir /usr/local/redis
Extract:
The tar – ZXVF 3.0.0 – rc5. Tar. Gz
The mv redis – 3.0.0 – rc5 redis3.0
CD redis3.0
Install (use PREFIX to specify the installation directory) :
make PREFIX=/usr/local/redis install
/usr/local/redis = /usr/local/redis = /usr/local/redis = /usr/local/redis = /usr/local/redis
redis-benchmark redis-check-aof redis-check-dump redis-cli redis-server
Configuring Redis as a service:
According to the above steps, Redis startup scripts for: / usr/local/SRC/redis3.0 / utils/redis_init_script
Copy the startup script to /etc/rc.d/init.d/ and name it redis
Cp/usr/local/SRC/redis3.0 / utils/redis_init_script/etc/rc. D/init. D/redis
Edit /etc/rc.d/init.d/redis to make it register as a service:
vi /etc/rc.d/init.d/redis
#! /bin/sh
Simple Redis init.d script conceived to work on Linux systems
as it does use of the /proc filesystem.
REDISPORT=6379
EXEC=/usr/local/bin/redis-server
CLIEXEC=/usr/local/bin/redis-cli
PIDFILE=/var/run/redis_${REDISPORT}.pid
CONF=”/etc/redis/${REDISPORT}.conf”
case “$1” in
start)
if [ -f $PIDFILE ]
then
echo “$PIDFILE exists, process is already running or crashed”
else
echo “Starting Redis server…”
fi
;;
stop)
if [ ! -f $PIDFILE ]
then
echo “$PIDFILE does not exist, process is not running”
else
PID=
echo “Stopping …”
while [ -x /proc/${PID} ]
do
echo “Waiting for Redis to shutdown …”
sleep 1
done
echo “Redis stopped”
fi
;;
*)
echo “Please use start or stop as first argument”
;;
esac
Check the above redis service script, pay attention to the attributes marked orange, and prepare the following changes:
(1) Add the following line after the first line of the script:
#chkconfig: 2345 80 90
Note: Service redis does not support chkconfig will be displayed during service registration if the preceding content is not added
(2) REDISPORT port remains unchanged at 6379; (Special note: The port name is related to the configuration file name below)
(3) the EXEC = / usr/local/bin/redis server to EXEC = / usr/local/redis/bin/redis server. –
(4) CLIEXEC = / usr/local/bin/redis – cli to CLIEXEC = / usr/local/redis/bin/redis – cli
(5) Configuration file Settings:
Create the redis profile directory
mkdir /usr/local/redis/conf
Copy the redis configuration file/usr/local/SRC/redis3.0 / redis conf to/usr/local/redis/conf directory and the port number to 6379. Conf
Cp/usr/local/SRC/redis3.0 / redis conf/usr/local/redis/conf / 6379. Conf
After the preceding preparations, modify the CONF attributes as follows:
CONF=”/etc/redis/
(6) Change the command enabled by Redis and execute it in the background:
The content of the modified /etc/rc.d/init.d/redis service script is as follows:
#! /bin/sh
#chkconfig: 2345 80 90
Simple Redis init.d script conceived to work on Linux systems
as it does use of the /proc filesystem.
REDISPORT=6379
EXEC=/usr/local/redis/bin/redis-server
CLIEXEC=/usr/local/redis/bin/redis-cli
PIDFILE=/var/run/redis_${REDISPORT}.pid
CONF=”/usr/local/redis/conf/${REDISPORT}.conf”
case “$1” in
start)
if [ -f $PIDFILE ]
then
echo “$PIDFILE exists, process is already running or crashed”
else
echo “Starting Redis server…”
fi
;;
stop)
if [ ! -f $PIDFILE ]
then
echo “$PIDFILE does not exist, process is not running”
else
PID=
echo “Stopping …”
while [ -x /proc/${PID} ]
do
echo “Waiting for Redis to shutdown …”
sleep 1
done
echo “Redis stopped”
fi
;;
*)
echo “Please use start or stop as first argument”
;;
esac
After the above configuration is complete, you can register Redis as a service:
chkconfig –add redis
Open the corresponding port on the firewall
vi /etc/sysconfig/iptables
Add:
-A INPUT -m state –state NEW -m tcp -p tcp –dport 6379 -j ACCEPT
Restart the firewall:
service iptables restart
Modify redis profile Settings:
vi /usr/local/redis/conf/6379.conf
Modify the following configuration:
Daemonize no daemonize yes
Note: If the pid file is not changed to yes, the pid file will not be generated, and the start and stop commands will not take effect (dependent on the PID file).
Pid to pidfile /var/run/redis_6379.pid
Start the Redis service
service redis start
Add Redis to the environment variable:
vi /etc/profile
Add the following at the end:
Redis env
export PATH=$PATH:/usr/local/redis/bin
To make the configuration take effect:
source /etc/profile
You can run redis commands such as redis-cli directly.
redis-cli
Stop the Redis service
service redis stop
Remind: by default, Redis open security certification, can use the/usr/local/Redis/conf / 6379. The requirepass specify a conf
