What are the methods to start redis in Linux?
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
nohup 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 plays a key role in data storage and management, and has become the core of modern applications through its multiple data structures and persistence mechanisms. 1) Redis supports data structures such as strings, lists, collections, ordered collections and hash tables, and is suitable for cache and complex business logic. 2) Through two persistence methods, RDB and AOF, Redis ensures reliable storage and rapid recovery of data.
