[Linux] install and configure redis3.2.3 on CentOS 7, centosredis3.2.3
I. Install redis source code

As of January 11, the latest stable version of redis is 3.2.3. This article is based on this version.

Download the redis source code and perform the following operations:

Wget http://download.redis.io/releases/redis-3.2.3.tar.gz

Tar-zxvf redis-3.2.3.tar.gz

Music redis-3.2.3 redis

After decompression, install the tool as follows:

Cd redis

Make & make install

Through this, we can easily see that redis is installed to/usr/local,/usr/local/bin,/usr/local/share,/usr/local/include, /usr/local/lib,/usr/local/share/man directory.

Then switch to the utils directory and execute the redis Initialization Script install_server.sh, as shown below:

Cd utils/

./Install_server.sh

Port: 6379

Config file:/etc/redis/6379. conf

Log file:/var/log/redis_62.16.log

Data dir:/var/lib/apsaradb for redis/6379

Executable:/usr/local/bin/redis-server

Cli Executable:/usr/local/bin/redis-cli

Copied/tmp/6379. conf =>/etc/init. d/redis_6379

Through, we can see that the redis configuration file after redis Initialization is/etc/redis/6379. conf: the log file is/var/log/redis_62.16.log, and the data file is dump. rdb is stored in the/var/lib/redis/6379 directory, and the startup script is/etc/init. d/redis_6379.

Now we want to use systemd, so in/etc/systems/systemCreate a unit file namedredis_6379.service.

1. vi/etc/systemd/system/redis_6379.service

Enter the following content. For details, see systemd. service.

1. [Unit]
2. Description=Redis on port 6379
3. [Service]
4. Type=forking
5. ExecStart=/etc/init.d/redis_6379 start
6. ExecStop=/etc/init.d/redis_6379 stop
7. [Install]
8. WantedBy=multi-user.target

 

Check the redis version and run the redis-cli-version command as follows:

Redis-cli-version

We can see that the redis version is 3.2.3.

Now we only need to start redis to use redis. The installation of redis in this source code method is complete.

Ii. yum Installation

After introducing the source code to install redis, We will install redis using yum. This article uses centos6.8 as an example. Run the following command:

Rpm-Uvh http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

Rpm-Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm

Yum-y-enablerepo = remi, remi-test install redis

After redis is installed, let's check the related files created during redis installation, as follows:

Rpm-qa | grep redis

Rpm-ql redis

We can see that the configuration file of redis is/etc/redis. conf, data file dump. rdb is stored in the/var/lib/redis/directory. The log file is/var/log/redis. log, others are default.

Check the redis version and run the redis-cli-version command as follows:

Redis-cli-version

We can see that the yum installation method is indeed the latest redis version.

Now we only need to start redis and we can use redis. The yum installation method is complete.

Iii. apt-get Installation

After the introduction of installing redis in yum mode, we will introduce how to install redis in Ubuntu through apt-get.

Based on the new version and old version of redis, we have made another distinction.

3.1 apt-get Install the latest version

To install the latest version of redis, first import the apt-get warehouse verification key, as shown below:

Wget-q-O-http://www.dotdeb.org/dotdeb.gpg | sudo apt-key add-

Or

Wget http://www.dotdeb.org/dotdeb.gpg

Sudo apt-key add dotdeb. gpg

After the verification file is installed, configure the apt-get repository as follows:

Vim/etc/apt/sources. list. d/redis. list

Deb http://packages.dotdeb.org wheezy all

Deb-src http://packages.dotdeb.org maid all

Note: This apt-get warehouse uses the debian apt-get warehouse. After multiple tests, we found that only the apt-get Warehouse can be installed to the latest redis version.

After configuring the apt-get repository, run the following command to install the Repository:

Sudo apt-get clean all

Sudo apt-get update

Sudo apt-get-y install redis-server

Through this, we can clearly see that the redis version is 3.2.3, the latest version. You can also run the redis-cli-version command. As follows:

Redis-cli-version

We can see that redis installed in this way is the latest version.

4. Configure redis

After redis is installed, We will configure redis again. In fact, for redis installation, we recommend that you install it directly through the source code. After the installation, the redis configuration file is complete.

To ensure security, you only need to enable the requirepass parameter of the redis password verification function.

The final redis configuration file is as follows:

Grep-Ev '^ # | ^ $'/etc/redis/6379. conf

Bind 127.0.0.1

Protected-mode yes

Port 6379

Tcp-Back log 511

Aof-rewrite-incremental-fsync yes

We will introduce these parameters in the configuration file in a later article. The redis configuration is complete.

V. Start and use redis

After configuring the redis configuration file, start redis and perform simple operations. As follows:

Redis-cli-h 127.0.0.1-p 6379-a ilanniredis

Keys *

Set ilanni testredis

Get ilanni

 

Let's explain the meaning of the above commands:

Redis-cli-h 127.0.0.1-p 6379-a ilanniredis

This command is used to connect to the redis server, with the IP address 127.0.0.1, port 6379, and password ilanniredis.

Keys * is to view all key-value pairs of redis.

Set ilanni testredis to add a key value ilanni with the content testredis.

Get ilanni view the content of the ilanni key value.
