Install and test Redis in CentOS 6.5

Install and test apsaradb for Redis-CentOS 6.5 using NoSQL

1. Download redis

You can install or download redis online.

① Check whether the rpm package does not exist before online installation. If you check whether the rpm package does not exist in yum online, you can only download the package manually or in other ways.

[Root @ localhost ~] # Rpm-qa | grep redis

[Root @ localhost ~] # Yum list | grep redis

It indicates that it does not exist.

② Go to the official website or download it online

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

Redis downloaded from the official website already exists. Click to download redis.

2. Installation

Because it is in the tar.gz format, you need to decompress and install

Find the path of the downloaded file

[Root @ localhost ~] # Whereis redis

Redis:/etc/redis

[Root @ localhost ~] #

The gcc environment is required for decompressing and compiling the redis software package.

In short, what installation is missing.

Tar-zxvf reids-2.8.13.tar.gz

Cd redis-2.8.13

Make

Sudo make install

# Start configuration ---

After compilation, the Src directory contains four executable files: redis-server, redis-benchmark, redis-cli, and redis. conf. Then copy it to a directory.

Mkdir/usr/redis

Cp redis-server/usr/redis

Cp redis-benchmark/usr/redis

Cp redis-cli/usr/redis

Cp redis. conf/usr/redis

Cd/usr/redis

# End of configuration --

Or you can configure it like this
Mkdir/etc/redis
Cp redis. conf/etc/redis. conf
Mkdir/var/lib/redis

You can download the modified redis. conf from here.
Start redis
Redis-server/etc/redis. conf
# You can start the redis service in the background and check whether it is running. You can run the redis-benchmark command to test it. You can also use the redis-cli command to perform the following operations:
# When installing, The redis command will be copied to/usr/local/bin.

3. Test

Check whether the client is successfully started.

[Root @ localhost src] # ps-aux | grep redis
Warning: bad syntax, perhaps a bogu '-'? See/usr/share/doc/procps-3.2.8/FAQ

4. Close the service
Redis-cli shutdown
If the port changes, you can specify the Port:
Redis-cli-p 6379 shutdown
127.0.0.1: 6379> I + j
Cocould not connect to Redis at 127.0.0.1: 6379: Connection refused
Not connected> set w 3
Cocould not connect to Redis at 127.0.0.1: 6379: Connection refused
Not connected>

5. Start the service
[Root @ localhost src] # redis-server

It is recommended that you re-open a window to run redsi-cli to enter the Console

Otherwise, a connection error may occur. Similar to running tomcat in windows cmd.
