這篇文章主要介紹了redis基本安裝判斷、啟動使用方法,結合實例形式分析了Redis針對是否安裝的判斷、啟動等使用方法,需要的朋友可以參考下
本文實例講述了redis基本安裝判斷、啟動使用方法。分享給大家供大家參考,具體如下:
1、Redis對否安裝(安裝好了會出現(xiàn)下面對應的代碼)
[root]$ whereis redis-cli redis-cli: /usr/local/bin/redis-cli [root]$ [root]$ whereis redis-server redis-server: /usr/local/bin/redis-server
2、啟動Redis
輸入代碼
redis-server &
30733:C 09 Dec 14:45:30.876 # Warning: no config file specified, using the default config. In order to specify a config file use redis-server /path/to/redis.conf
30733:M 09 Dec 14:45:30.879 # You requested maxclients of 10000 requiring at least 10032 max file descriptors.
30733:M 09 Dec 14:45:30.879 # Server can't set maximum open files to 10032 because of OS error: Operation not permitted.
30733:M 09 Dec 14:45:30.879 # Current maximum open files is 4096. maxclients has been reduced to 4064 to compensate for low ulimit. If you need higher maxclients increase 'ulimit -n'.

30733:M 09 Dec 14:45:30.900 # WARNING: The TCP backlog setting of 511 cannot be enforced because /proc/sys/net/core/somaxconn is set to the lower value of 128.

30733:M 09 Dec 14:45:30.901 # 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.
30733:M 09 Dec 14:45:30.901 # 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.
30733:M 09 Dec 14:45:30.902 * The server is now ready to accept connections on port 6379
3.判斷Redis是否啟動
[root]# redis-cli -p 6379 127.0.0.1:6379> ping PONG 127.0.0.1:6379>
希望本文所述對大家Redis數(shù)據(jù)庫程序設計有所幫助。
