Redis - how to install redis and configuration (how to quickly install redis on ubuntu18.04 and centos7.6 Linux systems)

How to install quickly Redis And configure environment variables

Ubuntu18.04 Linux Lower installation Redis

Preparation

redis-6.2.6.tar.gz Installation package

tcl8.6.1-src.tar Installation package （ To solve the problem make test In the process encounter “You need tcl 8.5 or newer in order to run the Redis test” The problem of ）

Ubuntu 18.04 Installation in environment

Step one ： Unzip and download it, and put it in ~/downloads/redis-6.2.6.tar.gz To /usr/local Directory and rename

#  Enter the directory where the user downloaded the installation package 
$ cd ~/downloads
#  decompression  redis-6.2.6.tar.gz  To  /usr/local  Under the table of contents 
$ sudo tar -zxvf redis-6.2.6.tar.gz -C /usr/local
#  Go to the application folder 
$ cd /usr/local
#  rename 
$ sudo mv ./redis-6.2.6 ./redis
#  Change folder permissions 
$ sudo chown -R hadoop ./redis/

Step two ： Enter into /usr/local/redis/src Compile below (make)

$ cd /usr/local/redis/src && make

Pay attention to point one ： If there is Command ‘gcc’ not found , because redis It was the author who passed C Written in language , There is no installation in the system gcc Or the version is too low to compile and run , There is no such instruction operation to compile .

Solution

#  Update installation source 
$ sudo apt-get update
#  install  gcc
$ sudo apt-get install gcc

After completing the above operations , Again in /usr/local/redis/src Execute under directory make

Pay attention to point two ： When we do it again make On command , Show error: jemalloc/jemalloc.h: No such file or directory when , Official documents suggest that this is about the distributor allocator The problem of , If there is MALLOC This environment variable , We'll use this environment variable To build Redis.libc It's not the default allocator , The default is jemalloc because jemalloc Proved to be better than libc Less fragmentation problems, In order to solve the problem caused by the above default values . We just need to do the following ：

$ make MALLOC=libc

After completing the above operations , Again in /usr/local/redis/src Execute under directory make

Step three ： Conduct make test test redis The function of

$ make test

Pay attention to point one ： In execution redis The test command make test In the process , encounter “You need tcl 8.5 or newer in order to run the Redis test” The problem with

Solution

Will be ready tcl8.6.1-src.tar.gz Extract and configure the installation

#  Enter the directory where the user downloaded the installation package 
$ cd ~/downloads
#  decompression  tcl8.6.1-src.tar.gz  Go to the specified directory 
$ tar -zxvf ./tcl8.6.1-src.tar.gz -C ~/software
$ cd ~/software/tcl8.6.1/unix
#  Enter the software and start the configuration 
$ sudo ./configure
#  install 
$ sudo make
$ sudo make install

After completing the above operations , Enter into /usr/local/redis/src Under the table of contents perform make test Conduct redis test

Step four ： install redis After and start

$ cd /usr/local/redis/src
$ sudo make install
$ redis-server

The startup is successful, as shown in the figure ：

Configure environment variables

#  Modify environment variable configuration 
$ vim ~/.bashrc
#  Make the modification of environment variable configuration effective 
$ source ~/.bashrc

~./bashrc Ubuntu18.04 Next

export REDIS_HOME=/usr/local/redis
export PATH=${REDIS_HOME}/src:${JAVA_HOME}/bin:${HADOOP_HOME}/bin:${HADOOP_HOME}/sbin:${HBASE_HOME}/bin:${ZOOKEEPER_HOME}/bin:${MY_HOME}/bin:$PATH

CentOS 7.6 Linux Lower installation Redis

Preparation

redis-6.2.6.tar.gz Installation package

CentOS 7.6 Installation in environment

Step one : install Redis rely on

because Redis Is based on C Written in language , So first you need to install Redis The required gcc rely on .

sudo yum install -y gcc tcl

Step two ： Unzip and download it, and put it in ~/downloads/redis-6.2.6.tar.gz To /usr/local Directory and rename

#  Enter the directory where the user downloaded the installation package 
$ cd ~/downloads
#  decompression  redis-6.2.6.tar.gz  To  /usr/local  Under the table of contents 
$ sudo tar -zxvf redis-6.2.6.tar.gz -C /usr/local
#  Go to the application folder 
$ cd /usr/local
#  rename 
$ sudo mv ./redis-6.2.6 ./redis
#  Change folder permissions 
$ sudo chown -R hadoop ./redis/

Step three ： Enter the redis After the folder Installation

#  Go to decompress the good  redis  Under the table of contents 
$ cd /usr/local/redis

$ make && make install
#  The default path after installation is  /usr/local/bin  Under the table of contents 
$ cd /usr/local/bin
#  Check if the installation is successful

Step four ： Start and test

#  Because the global environment variables have been configured, you can start directly 
$ redis-server
#  test
