Linux System Installation and Configuration of Standalone Redis

Redis is used as a stateful server in Web clusters, mainly for storing cached logins, template locks, SessionIDs, WebSockets, etc. It plays and authenticates all accesses and operations.

2.1 Installing the gcc compiler

This step relies on the gcc compiler. If you do not have a gcc environment, you will need to install the package yourself.  

yum install gcc gcc-c++ ，As shown below.

gcc -v ##Check for gcc compiler

2.2 Download Redis

There are two ways to download Redis-5.0.4, either from the official website or by downloading the recommended version.

1）Official Website Download：http://download.redis.io/releases/

2）Redis-5.0.4：redis-5.0.4.tar.gz

2.3 Installing Redis

mkdir /usr/redis  # Creating a Redis Directory
cd /usr/redis  # Go to catalog
# Transfer the Redis installation package to this directory#
tar -zxvf redis-5.0.4.tar.gz  # Unzip the installation package
cd /usr/redis/redis-5.0.4  # Go to the decompression directory
make 
make test
make install  # installation command
redis-server -v  # Check the installation results

2.4 Modify configuration

Go to the edit file, as follows.

vi /usr/redis/redis-5.0.4/redis.conf # Edit the redis.conf configuration file

Modify the following.

bind 127.0.0.1 ---> # bind 127.0.0.1
protected-mode yes ---> protected-mode no
daemonize no ---> daemonize yes # Runs as a background program by default, no need 
to add & force the background to run
port 6379 ---> port 7379  # Change the port number to 7379
pidfile /var/run/redis_6379.pid ---> pidfile /var/run/redis_7379.pid  #  Change the 
port number to 7379
# requirepass foobared ---> requirepass 123456  # 123456 is the password can be 
replaced at will
maxmemory 4294967296  # Configure memory to 4G unit is byte,
 can also be configured to other sizes, the recommended size is 4G (need to add content)
maxmemory-policy allkeys-lru # Expiration policy,
 LRU Least Recent Use algorithm (content to be added)

2.5 Starting Redis

cd /usr/redis/redis-5.0.4/src #Go to the src directory
./redis-server /usr/redis/redis-5.0.4/redis.conf #Specify the configuration 
file when starting Redis
redis-cli -p port -a password #Local start Redis client, 
you can view key values, delete key values, check redis status and other operations

cd /usr/redis/redis-5.0.4/src #Go to the src directory
. /redis-server /usr/redis/redis-5.0.4/redis.conf #Specify the configuration file 
when starting Redis
redis-cli -p port -a password #Local start Redis client, you can view key values, 
delete key values, check redis status, etc.
redis-cli -p port -a password shutdown #Stop redis
redis-cli -h ip -p port -a password #Remotely connect to the Redis service, 
ip and port are the Redis service to connect to
