本文实例讲述了redis基本安装判断、启动使用方法。分享给大家供大家参考,具体如下:
1、Redis对否安装(安装好了会出现下面对应的代码)
[root]$ whereis redis-cli redis-cli: /usr/local/bin/redis-cli [root]$ [root]$ whereis redis-server redis-server: /usr/local/bin/redis-server
2、启动Redis
输入代码
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'. [root]$ _._ _.-``__ ''-._ _.-`` `. `_. ''-._ Redis 3.2.0 (00000000/0) 64 bit .-`` .-```. ```\/ _.,_ ''-._ ( ' , .-` | `, ) Running in standalone mode |`-._`-...-` __...-.``-._|'` _.-'| Port: 6379 | `-._ `._ / _.-' | PID: 30733 `-._ `-._ `-./ _.-' _.-' |`-._`-._ `-.__.-' _.-'_.-'| | `-._`-._ _.-'_.-' | http://redis.io `-._ `-._`-.__.-'_.-' _.-' |`-._`-._ `-.__.-' _.-'_.-'| | `-._`-._ _.-'_.-' | `-._ `-._`-.__.-'_.-' _.-' `-._ `-.__.-' _.-' `-._ _.-' `-.__.-' 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 14:45:30.900 # Server started, Redis version 3.2.0 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.判断Redis是否启动
[root]# redis-cli -p 6379 127.0.0.1:6379> ping PONG 127.0.0.1:6379>
希望本文所述对大家Redis数据库程序设计有所帮助。

稳了!魔兽国服回归的3条重磅消息!官宣时间再确认!
昨天有一位朋友在大神群里分享,自己亚服账号被封号之后居然弹出了国服的封号信息对话框。
这里面让他访问的是一个国服的战网网址,com.cn和后面的zh都非常明白地表明这就是国服战网。
而他在复制这个网址并且进行登录之后,确实是网易的网址,也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情,因为以前都没有出现这样的情况,现在突然提示跳转到国服战网的网址,是不是说明了简体中文客户端已经开始进行更新了呢?
