NoSQL Redis-centos 6.5 Installation test

1. Download Redis

redis

① before the online installation needs to detect whether there is a RPM package does not exist, to see if the Yum online RPM package does not exist, it can only be downloaded manually or in other ways to download

[[email protected] ~]# rpm-qa|grep redis[[email protected] ~]# yum List|grep redis

The description does not exist.

② to download the website or download it online

wget http://redis.googlecode.com/files/redis-2.2.13.tar.gz

There is already a blog in the download of Redis , click to download redis.

2. Installation

Because it is tar.gz format, it needs decompression and installation

Find the path to the downloaded file after downloading it.

[Email protected] ~]# Whereis Redisredis:/etc/redis[[email protected] ~]#

Extracting a Redis-compiled package requires a GCC environment

In short what is missing what to install.

TAR-ZXVF reids-2.8.13.tar.gzcd Redis-2.8.13makesudo make install# configuration starts---There are four executable files in the SRC directory after the compilation is completed Redis-server, Redis-benchmark, Redis-cli and redis.conf. And then copy it to a directory. MKDIR/USR/REDISCP REDIS-SERVER/USR/REDISCP REDIS-BENCHMARK/USR/REDISCP REDIS-CLI/USR/REDISCP Redis.conf/usr/redisc d/usr/redis# Configuration End--

Or you can configure this

MKDIR/ETC/REDISCP Redis.conf/etc/redis/redis.confmkdir/var/lib/redis

You can download the modified redis.conf from here

Start redisredis-server/etc/redis/redis.conf# to start the Redis service in the background after the confirmation is run, you can use the Redis-benchmark command test to see if you can actually do it with the REDIS-CLI command, like #install的时候redis的命令会被拷贝到/usr/local/bin down.

3. Testing

The client tests if the start is successful

[[email protected] src]# ps -aux|grep rediswarning: bad syntax,  perhaps a bogus  '-'? see /usr/share/doc/procps-3.2.8/faqroot      23266  0.0  0.7 137356  7768 ?         Sl   00:23   0:04 redis-server *:6379root      23982  0.0  0.5  19404  5100 pts/0     S+   01:09   0:00 redis-cliroot      24398  0.0  0.0 103244   876 pts/2    s +   01:44   0:00 grep redis[[email protected] src]#  Redis-cli127.0.0.1:6379> set w wangok127.0.0.1:6379> get w "Wang" 127.0.0.1:6379 >

4. Close the service

REDIS-CLI shutdown If port change can specify port: Redis-cli-p 6379 shutdown

127.0.0.1:6379> i+jcould not connect to Redis at 127.0.0.1:6379:connection Refusednot connected> set W 3Could not C Onnect to Redis at 127.0.0.1:6379:connection Refusednot connected>

5. Start the service

It's best to reopen a window after launch redsi-cLi enters the console

Otherwise, a connection error may occur. Similar to running Tomcat under Windows CMD.
