2. Download the redis installation package
First, you need to go to the Redis official website to download the Redis source code package, click to enter the official website , and click Download 7.0.10 to download, as shown in the red box in the figure below.
Or execute the following command to download directly, as shown below.
As you can see above, the download speed is very fast. After the download is complete, execute the following command to decompress the source code package.
root@hcss-ecs-f276:~# tar -zxvf 7.0.10.tar.gzAs shown below, decompression is complete.
3. Compile the source code
Install the environment required for compilation.
root@hcss-ecs-f276:~# sudo apt install build-essential -yExecute the above command to install and compile the software packages that C/C++ depends on, such as: gcc, g++, make, etc.
Execute the following command to compile the source code.
root@hcss-ecs-f276:~/redis-7.0.10# sudo make -j4After executing the command, the following is displayed.
To install redis, execute the following command.
root@hcss-ecs-f276:~/redis-7.0.10# sudo make PREFIX=/usr/local/redis installAfter executing the command, the following is displayed.
Install redis to the /usr/local/redis directory.
4. Run Redis
Execute the following command to place redis-server and redis-cli in the system path (/usr/bin).
root@hcss-ecs-f276:~/redis-7.0.10# ln -s /usr/local/redis/bin/redis-cli /usr/bin/redis-cli
root@hcss-ecs-f276:~/redis-7.0.10# ln -s /usr/local/redis/bin/redis-server /usr/bin/redis-serverThe above command is to establish a soft connection, let /usr/bin/redis-cli point to /usr/local/redis/bin/redis-cli, let /usr/bin/redis-server point to /usr/local/redis/bin/redis -server.
Configure redis-server, copy the redis.conf configuration file in the source directory to the installation directory, and execute the following command.
root@hcss-ecs-f276:~# sudo cp redis-7.0.10/redis.conf /usr/local/redis/Modify the redis.conf file as follows.
#（1）修改 1
# 注释掉 bind 127.0.0.1 -::1 允许远程连接
#bind 127.0.0.1 -::1
# （2）修改2
# 将 daemonize no 修改为 daemonize yes，设置后台运行
daemonize yes
# （3）修改3
# 指定 log 文件路径
logfile "/var/log/redis-server.log"
# （4）修改4
# 设置登录密码
requirepass 123456Start redis-server and execute the following command.
root@hcss-ecs-f276:~# sudo redis-server /usr/local/redis/redis.conf
root@hcss-ecs-f276:~# ps -ef | grep redis
root 24488 1 0 21:22 ? 00:00:00 redis-server *:6379
root 24495 19372 0 21:23 pts/1 00:00:00 grep --color=auto redis
root@hcss-ecs-f276:~#To access through the client, execute the following command.
root@hcss-ecs-f276:~# redis-cli
127.0.0.1:6379> auth 123456
OK
127.0.0.1:6379> ping
PONG
127.0.0.1:6379>
root@hcss-ecs-f276:~#Auth is followed by the login password set in the configuration file redis.conf. Enter ping. If PONG is returned, the connection to the Redis server is successful.
Close redis-server and execute the following command.
root@hcss-ecs-f276:~# redis-cli
127.0.0.1:6379> auth 123456
OK
127.0.0.1:6379> ping
PONG
127.0.0.1:6379> shutdown
not connected>
root@hcss-ecs-f276:~# ps -ef | grep redis
root 26321 26241 0 22:05 pts/3 00:00:00 grep --color=auto redis
root@hcss-ecs-f276:~#5. Set up auto-start at boot
Copy the startup script redis_init_script to the directory /etc/init.d/redis and execute the command as shown below.
root@hcss-ecs-f276:~# sudo cp redis-7.0.10/utils/redis_init_script /etc/init.d/redisModify the /etc/init.d/redis file as follows.
REDISPORT=6379
#EXEC=/usr/local/bin/redis-server
# 修改 redis-server 路径，之前的配置已经放置到系统路径 /usr/bin 下。
EXEC=/usr/bin/redis-server
# 修改 redis-cli 路径，之前的配置已经放置到系统路径 /usr/bin 下。
#CLIEXEC=/usr/local/bin/redis-cli
CLIEXEC=/usr/bin/redis-cli
PIDFILE=/var/run/redis_${REDISPORT}.pid
CONF="/etc/redis/${REDISPORT}.conf"In the above code, CONF represents the path of the configuration file to be read. You need to create the redis directory in the /etc directory, copy redis.conf to /etc/redis/ and rename it to 6379.conf. Execute the following command to configure.
root@hcss-ecs-f276:~# vim /etc/init.d/redis
root@hcss-ecs-f276:~# sudo mkdir /etc/redis
root@hcss-ecs-f276:~# sudo cp /usr/local/redis/redis.conf /etc/redis/6379.conf
root@hcss-ecs-f276:~#Add redis to enable auto-start and start the redis service. Execute the command as shown below.
root@hcss-ecs-f276:~# sudo update-rc.d -f redis defaults
root@hcss-ecs-f276:~# systemctl start redis
root@hcss-ecs-f276:~# systemctl status redis
