Summarize the three startup methods of redis

redis的启动方式

1.直接启动

  进入redis根目录,执行命令:

  #加上‘&’号使redis以后台程序方式运行

./redis-server &
Copy after login

2.通过指定配置文件启动

可以为redis服务启动指定配置文件,例如配置为/etc/redis/6379.conf

进入redis根目录,输入命令:

./redis-server /etc/redis/6379.conf
Copy after login

#如果更改了端口,使用`redis-cli`客户端连接时,也需要指定端口,例如:

redis-cli -p 6380
Copy after login

3.使用redis启动脚本设置开机自启动

启动脚本 redis_init_script 位于位于Redis的 /utils/ 目录下,redis_init_script脚本代码如下:

#!/bin/sh
#
# Simple Redis init.d script conceived to work on Linux systems
# as it does use of the /proc filesystem.
 
#redis服务器监听的端口
REDISPORT=6379
 
#服务端所处位置
EXEC=/usr/local/bin/redis-server
 
#客户端位置
CLIEXEC=/usr/local/bin/redis-cli
 
#redis的PID文件位置,需要修改
PIDFILE=/var/run/redis_${REDISPORT}.pid
 
#redis的配置文件位置,需将${REDISPORT}修改为文件名
CONF="/etc/redis/${REDISPORT}.conf"
 
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
        ;;
    *)
        echo "Please use start or stop as first argument"
        ;;
esac
Copy after login

根据启动脚本,将修改好的配置文件复制到指定目录下,用root用户进行操作:

mkdir /etc/redis
cp redis.conf /etc/redis/6379.conf
Copy after login

将启动脚本复制到/etc/init.d目录下,本例将启动脚本命名为redisd(通常都以d结尾表示是后台自启动服务)。

cp redis_init_script /etc/init.d/redisd
Copy after login

设置为开机自启动,直接配置开启自启动 chkconfig redisd on 发现错误: service redisd does not support chkconfig

解决办法,在启动脚本开头添加如下注释来修改运行级别:

#!/bin/sh
# chkconfig:   2345 90 10
Copy after login

再设置即可

#设置为开机自启动服务器
chkconfig redisd on
#打开服务
service redisd start
#关闭服务
service redisd stop
Copy after login

How to build the redis cluster mode How to build the redis cluster mode Apr 10, 2025 pm 10:15 PM

Redis cluster mode deploys Redis instances to multiple servers through sharding, improving scalability and availability. The construction steps are as follows: Create odd Redis instances with different ports; Create 3 sentinel instances, monitor Redis instances and failover; configure sentinel configuration files, add monitoring Redis instance information and failover settings; configure Redis instance configuration files, enable cluster mode and specify the cluster information file path; create nodes.conf file, containing information of each Redis instance; start the cluster, execute the create command to create a cluster and specify the number of replicas; log in to the cluster to execute the CLUSTER INFO command to verify the cluster status; make

How to clear redis data How to clear redis data Apr 10, 2025 pm 10:06 PM

How to clear Redis data: Use the FLUSHALL command to clear all key values. Use the FLUSHDB command to clear the key value of the currently selected database. Use SELECT to switch databases, and then use FLUSHDB to clear multiple databases. Use the DEL command to delete a specific key. Use the redis-cli tool to clear the data.

How to use the redis command How to use the redis command Apr 10, 2025 pm 08:45 PM

Using the Redis directive requires the following steps: Open the Redis client. Enter the command (verb key value). Provides the required parameters (varies from instruction to instruction). Press Enter to execute the command. Redis returns a response indicating the result of the operation (usually OK or -ERR).

How to use redis lock How to use redis lock Apr 10, 2025 pm 08:39 PM

Using Redis to lock operations requires obtaining the lock through the SETNX command, and then using the EXPIRE command to set the expiration time. The specific steps are: (1) Use the SETNX command to try to set a key-value pair; (2) Use the EXPIRE command to set the expiration time for the lock; (3) Use the DEL command to delete the lock when the lock is no longer needed.

How to read redis queue How to read redis queue Apr 10, 2025 pm 10:12 PM

To read a queue from Redis, you need to get the queue name, read the elements using the LPOP command, and process the empty queue. The specific steps are as follows: Get the queue name: name it with the prefix of "queue:" such as "queue:my-queue". Use the LPOP command: Eject the element from the head of the queue and return its value, such as LPOP queue:my-queue. Processing empty queues: If the queue is empty, LPOP returns nil, and you can check whether the queue exists before reading the element.

How to implement the underlying redis How to implement the underlying redis Apr 10, 2025 pm 07:21 PM

Redis uses hash tables to store data and supports data structures such as strings, lists, hash tables, collections and ordered collections. Redis persists data through snapshots (RDB) and append write-only (AOF) mechanisms. Redis uses master-slave replication to improve data availability. Redis uses a single-threaded event loop to handle connections and commands to ensure data atomicity and consistency. Redis sets the expiration time for the key and uses the lazy delete mechanism to delete the expiration key.

How to read the source code of redis How to read the source code of redis Apr 10, 2025 pm 08:27 PM

The best way to understand Redis source code is to go step by step: get familiar with the basics of Redis. Select a specific module or function as the starting point. Start with the entry point of the module or function and view the code line by line. View the code through the function call chain. Be familiar with the underlying data structures used by Redis. Identify the algorithm used by Redis.

How to make message middleware for redis How to make message middleware for redis Apr 10, 2025 pm 07:51 PM

Redis, as a message middleware, supports production-consumption models, can persist messages and ensure reliable delivery. Using Redis as the message middleware enables low latency, reliable and scalable messaging.
