Linux-Redis 6.2.6 installation notes Records
Historical installation records: Linux-6.2.1 , Linux-6.0.10
1. Download the latest stable version from the official website
wget https://download.redis.io/releases/redis-6.2.6.tar.gz
2. Unzip
yum install -y tar
tar -zxvf redis-6.2.6.tar.gz
3. Create a soft link
ln -s redis-6.2.6 redis (或者直接改: mv redis-6.2.6 redis)
4. Enter the redis directory
cd redis
5. Start compiling
In order to avoid compilation errors, first upgrade the gcc version:
gcc -v
yum -y install centos-release-scl
yum -y install devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutilsscl enable devtoolset-9 bash
Start compiling:
make
6. Compile and install:
make install
7. Modify the configuration file:
vi redis.conf
（按Esc退出编辑模式下： /protected-mode 即可搜索）
protected-mode no # 关闭保护模式
daemonize yes # 守护进程模式开启
#bind 127.0.0.1 # 绑定IP按需修改，bind指定网段远程访问redis，注释就没有限制了。
port 6379 # 端口（单机默认，集群按需修改）
requirepass 123456 # （搜/requirepass foobared）设置Redis密码
Note: The cloud server must set a password to prevent the server from being regarded as a mining machine
8. redis startup: enter the src directory
cd src
Start command: (start command + configuration file + background start)
./redis-server /usr/local/redis/redis.conf &
View process:
ps -ef | grep redis
Built-in client connection test:
(connection command + IP + port number + password)
./redis-cli -h 127.0.0.1 -p 6379 -a 123456
Tool remote connection test:
redis shutdown command:
redis-cli shutdown
9 Relevant file analysis:
redis-server server startup command
redis-cli client startup command
redis.conf redis core configuration file
redis-check-dump RDB file inspection tool (snapshot persistent file)
redis-check-aof AOF file repair tool
10 boot configuration
10.1 Create a redis directory under the etc directory
mkdir /etc/redis
10.2 Copy the redis configuration file to the etc/redis directory
cp /usr/local/redis/redis.conf /etc/redis/6379.conf
10.3 File authorization to avoid file execution without permission
chmod 755 /etc/redis/6379.conf
10.4 Then enter the /redis/utils directory and copy the startup script redis_init_script and rename it to redis
cp /usr/local/redis/utils/redis_init_script /etc/init.d/redis
10.5 Modify redis script
vi /etc/init.d/redis
首行添加:
#chkconfig: 2345 10 90
#description: Start and Stop redis
Modify the corresponding startup service location
EXEC=/usr/local/redis/src/redis-server
CLIEXEC=/usr/local/redis/src/redis-cli
As shown below:

#!/bin/sh
# chkconfig: 2345 10 90
# description: Start and Stop redis
# Simple Redis init.d script conceived to work on Linux systems
# as it does use of the /proc filesystem.

esac
10.6 Enable autostart
chkconfig redis on
10.7 You can test whether the startup and shutdown are normal
stop:
service redis stop
(It will prompt that the command line is not safe to add a password, ignore it for now)
Start:
service redis start
View process
ps -ef | grep redis
10.8 reboot Restart the host and check whether redis starts automatically
reboot
ps -ef | grep redis
Thanks for reading, this is the end for now.
