Linux下Redis的安装和使用

1.Redis的安装

Redis下载：http://redis.io/download 在页面下方Redis提供了linux下安装的指令

wget http://download.redis.io/releases/redis-2.8.7.tar.gz

tar xzf redis-2.8.7.tar.gz

cd redis-2.8.7

make

注意：make指令是需要linux下安装gcc的 如果没有gcc可以尝试安装

yum -y install gcc

另外可能还会遇到其它的一些问题

可以参考：

比如32位Linux安装redis的解决 http://www.linuxidc.com/Linux/2014-05/101980.htm 与 http://www.linuxidc.com/Linux/2014-05/101981.htm

由于自己对Linux也不太熟悉，当时make的时候不成功，就试了网上的各种方法，最主要的原因是make需要gcc

2.Redis的使用

在Redis目录下 开启Redis 这个窗口就不能继续操作了

scr/redis-server

另开启一个命令行窗口 进入Redis目录 可以进行测试

src/redis-cli

[root@localhost src]# ./redis-cli
127.0.0.1:6379> set abc abcvalues
OK
127.0.0.1:6379> get abc
"abcvalues"
127.0.0.1:6379>

quit可以退出当前client

3.Redis的关闭

src/redis-cli shutdown

127.0.0.1:6379> quit
[root@localhost src]# ./redis-cli shutdown
[root@localhost src]#

4.补充 Ctrl+z

[root@localhost src]# ./redis-server

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.

src/redis-server 开启服务后 这个窗口是不能运行命令的 这个窗口可以关闭 服务不会关闭

如果在这个页面ctrl+z会把redis服务暂时挂起 可以通过 bg fg唤醒。
