Install and configure redis in the Linux environment, and set the boot auto start

1. Download from the official website tar package , Address ：https://redis.io/download

2. Uploaded to the /usr/local Directory and extract

tar -zxvf redis-6.0.7.tar.gz

3. install gcc Environmental Science

because redis By C language-written , Its operation requires C Environmental Science , So we need to install gcc. The installation command is as follows （ Select one or all ）：

yum -y install gcc gcc-c++ libstdc++-devel
yum install gcc-c++

4. If the following errors are reported during installation ：

 Compile error zmalloc.h:50:31: fatal error: jemalloc/jemalloc.h: No such file or directory


 perhaps 




server.c:2403:11:  error ：‘struct redisServer’ There is no name ‘assert_line’ Members of server.assert_line = 0;

The first error is solved as follows ：

Carry out orders ：

make MALLOC=libc

The second error is solved as follows ：

[[email protected] redis-6.0.7]# gcc -v                             #  see gcc edition 
[[email protected] redis-6.0.7]# yum -y install centos-release-scl  #  Upgrade to 9.1 edition 
[[email protected] redis-6.0.7]# yum -y install devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutils
[[email protected] redis-6.0.7]# scl enable devtoolset-9 bash
 The above is temporarily enabled , If you want to use it for a long time gcc 9.1 Words ：
[[email protected]t redis-6.0.7]# echo "source /opt/rh/devtoolset-9/enable" >>/etc/profile

5. Enter into   /usr/local/redis-6.0.7/ Under the table of contents , perform make Command to compile and install

6. Get into /usr/local/redis-6.0.7/src Under the table of contents , Perform the following installation ：

[[email protected] src]# make install

7. For the convenience of management , take Redis In the document conf Configuration files and common commands are moved to a unified file

(1) establish bin and etc Folder

[[email protected] redis-6.0.7]# mkdir bin
[[email protected] redis-6.0.7]# mkdir etc

(2)  take redis-6.0.7 In the catalog redis.conf Move to  redis-6.0.7 In the catalog etc Under the folder . take src Under the directory mkreleasehdr.sh、redis-benchmark、redis-check-aof、redis-cli、redis-server Move to    /usr/local/redis-6.0.7/bin/  Under the table of contents

[[email protected] redis-6.0.7]# mv redis.conf ./etc


[[email protected] src]# mv mkreleasehdr.sh redis-benchmark redis-check-aof redis-cli redis-server ../bin

8. edit /usr/local/redis-6.0.7/etc/redis.conf The configuration file , Set up background startup redis service

[[email protected] redis-6.0.7]# cd etc

[[email protected] etc]# vim redis.conf 

Modify the following properties ：

 Put... In the file daemonize Attribute to yes（ Indicates the need to run in the background ）
daemonize yes


 hold  redis.conf In the configuration file  bind 127.0.0.1  Comment out this line , there bind It means that only the specified network segment can remotely access this redis, When the notes are off , There is no such limitation .
#bind 127.0.0.1


 hold  redis.conf In the configuration file  protected-mode  Set to no（ The default setting is yes Of ,  Prevents remote access , stay redis3.2.3 After version ）
protected-mode no


 modify Redis Default password  ( The default password is empty ), Find this line in the configuration file  # requirepass foobared, Delete the previous comment symbol #, And put foobared Change to your own password    perhaps    Another line  requirepass  Your own code 
requirepass 123456

9. Configure power on self start

Enter folder , Write a self starting script

[[email protected] ~]# vim /etc/init.d/redis

The script is as follows ：

#!/bin/sh
# chkconfig: 2345 10 90 
# description: Start and Stop redis  
 
REDISPORT=6379 # Default port 
EXEC=/usr/local/redis-6.0.7/bin/redis-server #EXEC：redis Where the folder is located redis-server Location path 
CLIEXEC=/usr/local/redis-6.0.7/bin/redis-cli #CLIEXEC：redis Where the folder is located redis-cli Location path 
 
PIDFILE=/var/run/redis_${REDISPORT}.pid
CONF="/usr/local/redis-6.0.7/etc/redis.conf" #CONF：redis The configuration file used for startup 
 
case "$1" in
    start)
        if [ -f $PIDFILE ]
        then
                echo "$PIDFILE exists, process is already running or crashed"
        else
                echo "Starting Redis server..."
                $EXEC $CONF &
        fi
        ;;
    stop)
        if [ ! -f $PIDFILE ]
        then
                echo "$PIDFILE does not exist, process is not running"
        else
                PID=$(cat $PIDFILE)
                echo "Stopping ..."
                $CLIEXEC -p $REDISPORT shutdown
                while [ -x /proc/${PID} ]
                do
                    echo "Waiting for Redis to shutdown ..."
                    sleep 1
                done
                echo "Redis stopped"
        fi
        ;;
    restart)
        "$0" stop
        sleep 3
        "$0" start
        ;;
    *)
        echo "Please use start or stop or restart as first argument"
        ;;
esac

When it's done , Add permissions ：

[[email protected] ~]# chmod 777 /etc/init.d/redis

Set power on self start ：

[[email protected] ~]# chkconfig redis on

start-up redis command ：

[[email protected] ~]# service redis start

10. open RedisDesktopManager, Test whether the service is on as well as Can I access it remotely Redis

Many children report unknown errors during installation , Remind you to install the prerequisites first , such as gcc The environment has to be upgraded gcc Version, etc. .
