Comparison of various startup modes of Redis!
Have a feeling:
After playing with Redis for a long time, I really feel that the startup mode is still convenient by my own definition!
1) Direct startup and shutdown: (default for configuration file)
Enable: redis-server & (& run in the background)
# daemonize yes (this parameter can also be modified by configuration file)
Close: redis-cli shutdown or killall-9 redis-server
2) specify configuration file startup:
Redis-server / etc/redis.conf (configuration files can be defined by yourself)
If you change the redis default port:
Redis-cli shutdown (- p port)
Redis-cli shutdown (- p port) (- an authentication password)
3) define the startup file and configure it (recommended)
[root@redis1 ~] # cpredis-2.8.24/utils/redis_init_script / etc/init.d/redis
Register as a system service:
[root@redis1 ~] # sed-I'2i # chkconfig:2345 80 90' / etc/init.d/redis
[root@redis1] # chkconfig-- add redis
Modify the configuration file (because the path is defined by itself, sed can also)
REDISPORT=7000 # Note that slave ports can be defined by themselves
EXEC=/usr/local/redis/bin/redis-server
CLIEXEC=/usr/local/redis/bin/redis-cli
PIDFILE=/var/run/redis_$ {REDISPORT} .pid
CONF= "/ etc/redis/$ {REDISPORT} .conf"
The script is as follows (configured by yourself, you can also modify it on this basis)
#! / bin/sh#chkconfig: 2345 80 90# Simple Redis init.d script conceivedto work on Linux systems# as it does use of the / procfilesystem.
