Redis was introduced in the previous article, and the following is a record of installing Redis on CentOS. For later improvement.

1. Support environment required for installation

The first thing to do before installing Redis is to install Unix's Tcl tool. If you don't install it, you won't be able to test Redis later. The following error message is returned when make test is executed later: You need tcl 8.xuyao de5 or newer in order to run the Redis test. The specific process is as follows:

The copy code is as follows:

Cd / usr/local/src

Wget http://downloads.sourceforge.net/tcl/tcl8.6.3-src.tar.gz

Tar-zxvf tcl8.6.3-src.tar.gz

Cd tcl8.6.3/unix/

. / configure

Make

Make install

2. Install redis

The process of installing redis is very simple, and specific tutorials are also available on the official website. The details are as follows: http://redis.io/download

The copy code is as follows:

Cd / usr/local/src

Wget http://download.redis.io/releases/redis-2.8.19.tar.gz

Tar zxvf redis-2.8.19.tar.gz

Cd redis-2.8.19

Make

Make PREFIX=/usr/local/redis install

PREFIX=/usr/local/redis can be omitted. If omitted, redis will be installed in the / usr/local/bin directory by default.

3. Test Redis

The copy code is as follows:

Cd src

Make test

With the above command, you will be able to test redis more.

4. Configure redis

A. copy and modify the configuration document

The copy code is as follows:

Cp. / redis.conf / usr/local/redis/

Vim / usr/local/redis/redis.conf

I have only modified the following two items:

Daemonize yes # redis will run as a daemon. By default, no will temporarily use your terminal.

Timeout 300 # closes the connection when the client has been idle for how long. If specified as 0, the function is disabled.

More configuration content will be released after the follow-up carding is completed.

B. Set up automatic start

The copy code is as follows:

Vim / etc/init.d/redis

Save the following in the file:

The copy code is as follows:

#! / bin/sh

#

# redis Startup script for Redis Server

#

# chkconfig:-80 12

# description: Redis is an open source, advanced key-value store.

#

# processname: redis-server

# config: / etc/redis.conf

# pidfile: / var/run/redis.pid

Source / etc/init.d/functions

BIN= "/ usr/local/redis/bin"

CONFIG= "/ usr/local/redis/redis.conf"

PIDFILE= "/ var/run/redis.pid"

# Read configuration

[- r "$SYSCONFIG"] & & source "$SYSCONFIG"

RETVAL=0

Prog= "redis-server"

Desc= "Redis Server"

Start () {

If [- e $PIDFILE]; then

Echo "$desc already running...."

Exit 1

Fi

Echo-n $"Starting $desc:"

Daemon $BIN/$prog $CONFIG

RETVAL=$?

Echo

[$RETVAL-eq 0] & & touch / var/lock/subsys/$prog

Return $RETVAL

}

Stop () {

Echo-n $"Stop $desc:"

Killproc $prog

RETVAL=$?

Echo

[$RETVAL-eq 0] & & rm-f / var/lock/subsys/$prog $PIDFILE

Return $RETVAL

}

Restart () {

Stop

Start

}

Case "$1" in

Start)

Start

Stop)

Stop

Restart)

Restart

Condrestart)

[- e / var/lock/subsys/$prog] & & restart

RETVAL=$?

Status)

Status $prog

RETVAL=$?

*)

Echo $"Usage: $0 {start | stop | restart | condrestart | status}"

RETVAL=1

Esac

Exit $RETVAL

C, start or shut down the service

The copy code is as follows:

Service redis start

Service redis stop

5. Use redis

The copy code is as follows:

[root@localhost redis] # cd / usr/local/redis/bin

[root@localhost bin] #. / redis-cli

127.0.0.1 purl 6379 > set foo bar

OK

127.0.0.1 purl 6379 > get foo

"bar"

127.0.0.1purl 6379 >
