Summarize the three startup methods of redis
下面由Redis教程栏目给大家介绍三种redis的启动方式 ,希望对需要的朋友有所帮助!
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 &
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
#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
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
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
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
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
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

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: 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.

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.

On CentOS systems, you can limit the execution time of Lua scripts by modifying Redis configuration files or using Redis commands to prevent malicious scripts from consuming too much resources. Method 1: Modify the Redis configuration file and locate the Redis configuration file: The Redis configuration file is usually located in /etc/redis/redis.conf. Edit configuration file: Open the configuration file using a text editor (such as vi or nano): sudovi/etc/redis/redis.conf Set the Lua script execution time limit: Add or modify the following lines in the configuration file to set the maximum execution time of the Lua script (unit: milliseconds)

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).

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.

Use the Redis command line tool (redis-cli) to manage and operate Redis through the following steps: Connect to the server, specify the address and port. Send commands to the server using the command name and parameters. Use the HELP command to view help information for a specific command. Use the QUIT command to exit the command line tool.

There are two types of Redis data expiration strategies: periodic deletion: periodic scan to delete the expired key, which can be set through expired-time-cap-remove-count and expired-time-cap-remove-delay parameters. Lazy Deletion: Check for deletion expired keys only when keys are read or written. They can be set through lazyfree-lazy-eviction, lazyfree-lazy-expire, lazyfree-lazy-user-del parameters.
