一、啟動(dòng)redis
1.前臺(tái)啟動(dòng)
[root@iz2ze4jq06yojn4f8bm98kz redis-4.0.8]# ./src/redis-server

19367:M 15 Jan 18:26:32.375 # WARNING overcommit_memory is set to 0! Background save may fail under low memory condition. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.
19367:M 15 Jan 18:26:32.375 # WARNING you have Transparent Huge Pages (THP) support enabled in your kernel. This will create latency and memory usage issues with Redis. To fix this issue run the command 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' as root, and add it to your /etc/rc.local in order to retain the setting after a reboot. Redis must be restarted after THP is disabled.

2.后臺(tái)啟動(dòng)
[root@iz2ze4jq06yojn4f8bm98kz redis-4.0.8]# nohup ./src/redis-server &
nohup: ignoring input and appending output to ?.ohup.out?
解決：
1.查看日志：
[root@iz2ze4jq06yojn4f8bm98kz redis-4.0.8]# tail -f nohup.out
19394:C 15 Jan 18:31:38.184 # Warning: no config file specified, using the default config. In order to specify a config file use ./src/redis-server /path/to/redis.conf

好像已經(jīng)啟動(dòng)了，但是netstat -input|grep redis 沒有查到進(jìn)程
