Installation environment:

Linux:centos6.9 64 bit

Redis version: redis-4.0.2.tar.gz

Redis installation

Redis official website address: http://www.redis.io/

The latest version is 4.0.2.

1. Download the source code, decompress and compile the source code

[root@localhost ~] # wget http://download.redis.io/releases/redis-4.0.2.tar.gz

[root@localhost ~] # tar-xfredis-4.0.2.tar.gz

[root@localhost ~] # cd redis-4.0.2

[root@localhost redis-4.0.2] # make compilation

2. After the make compilation is completed, we see the following interface, which shows that we have successfully installed it.

We will see several more executable files in the redis-4.0.2/src directory, of which redis-server is used to start the service, redis-cli is used to start the client, the rest is not clear, you can check.

After the default make, if we start the redis service, we have to go to the installation directory every time, which is very tedious, so we can execute make install after make and put the generated binaries in the / usr/local/bin directory.

Make install

1. Make install will generate a file under the / usr/local/bin path (the one I run), and the redis executable will be copied to / usr/local/bin/

2. Make PREFIX=/opt/redis install specifies the installation directory, which will generate a bin path under / opt/redis. Here are the executable files.

Note: if an ordinary user needs root permission to execute make install, use sudo make install

3. Set up services

First copy the redis-4.0.2/utils/redis_init_script file to / etc/init.d and rename it to redis. Execute a command

Cp redis-4.0.2/utils/redis_init_script / etc/init.d/redis

Vi / etc/rc.d/init.d/redis

Add in the second line of the document

# chkconfig: 234580 90 .

Make sure there are redis-server and redis-cli files in / usr/local/redis/bin (if someone installed without using the make install command, you need to copy redis-server and redis-cli to the / usr/local/redis/bin directory in the installation directory, otherwise you won't find redis-server when the service starts) as shown in the second red box below.

You can see this line in the / etc/init.d/redis file: CONF= "/ etc/redis/$ {REDISPORT} .conf". So copy the redis configuration file to / etc/redis/ and rename it to 7200.conf.

Mkdir / etc/rediscp redis-4.0.2/redis.conf / etc/redis/7200.conf copy redis.conf to the installation directory cp redis.conf / opt/redis Note: CONF= "/ etc/redis/$ {REDISPORT} .conf" here you need to modify the configuration file of your installation path

4. Modify 7200.conf configuration file

# specify the port under which redis runs. Default is 6379port 7200#daemonize no. By default, redis does not run in the background. If you need to run in the background, change the value of this item to yesdaemonize yes # when redis is running in the background, Redis will put the pid file in / var/run/redis.pid by default, and you can configure it to another address. # when running multiple redis services, you need to specify different pid files and ports # pidfile / var/run/redis_6379.pid pidfile / var/run/redis_7200.pid # specify that redis only receives requests from this IP address. If it is not set, then all requests will be processed. # it is best to set the timeout period (in seconds) for setting client connections for this item # bind 127.0.0.in production environment. When the client does not issue any instructions during this period, closing the connection # 0 closes this setting timeout 0 # specifies the logging level # Redis supports a total of four levels: debug, verbose, notice, warning. By default, verbose# debug records a lot of information, which is used to develop and test useful information for # varbose, unlike debug to record as many common verbose as # notice. Commonly used in production environment # warning only very important or serious information will be recorded to the log loglevel debug # configuration log file address # default value is stdout, standard output, if the background mode will be output to / dev/null# to generate the default log file location # logfile "" logfile "/ var/log/redis/redis.log" # configuration persistence file location dir / opt/data/redisData

5. Two ways to start in the background

By default, the redis startup service monopolizes the input screen. There are two ways to start it in the background:

A. Find $EXEC $CONF in / etc/init.d/redis and add a & after it means let redis start b as a background service and modify the configuration file of redis. Conf (/ etc/redis/7200.conf) will configure whether some options are started in the foreground or background, if the background startup is set to yes)

6. Join service service management

Once you have done the above, you can register for the service:

Chkconfig-add redis

Then start the redis service

Service redis start

So we have registered the redis service.

If service redis stop, prompt / var/run/redis_7200.pid does not exist, process is not running

This shows that there is no this file under run. We really do not have this file before we go to / var/run, but there is a redis.pid file.

Solution:

A, modify the redis_$ {REDISPORT} .pid in the / etc/rc.d/init.d/redis file to redis.pidb, modify the pidfile / var/run/redis.pid in the 7200.conf configuration file to pidfile / var/run/redis_7200.pid, generate pid before deletion, and restart will generate the redis_7200.pid file.

In this way, after we restart the service, we can turn it off with this command. At this point, our redis service is installed and a service is ready.

The above is the whole process of installing Redis under Linux. I hope it will be helpful for you to install Redis.

Redis startup script is attached:
