在centos上安装Redis.
1. yum install redis --查看是否有redis yum 源
[root@localhost ~]# yum install redis Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirror.optus.net * extras: mirrors.cn99.com * updates: mirror.bit.edu.cn No package redis available. Error: Nothing to do
2. yum install epel-release --下载fedora的epel仓库
[root@localhost ~]# yum install epel-release Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirror.optus.net * extras: mirrors.cn99.com * updates: mirror.bit.edu.cn Resolving Dependencies --> Running transaction check ---> Package epel-release.noarch 0:7-11 will be installed --> Finished Dependency Resolution Dependencies Resolved =================================================================================================================================== Package Arch Version Repository Size =================================================================================================================================== Installing: epel-release noarch 7-11 extras 15 k Transaction Summary =================================================================================================================================== Install 1 Package Total download size: 15 k Installed size: 24 k Is this ok [y/d/N]: y Downloading packages: epel-release-7-11.noarch.rpm | 15 kB 00:00:00 Running transaction check Running transaction test Transaction test succeeded Running transaction Installing : epel-release-7-11.noarch 1/1 Verifying : epel-release-7-11.noarch 1/1 Installed: epel-release.noarch 0:7-11 Complete!
3 .yum install redis --安装Redis

4. service redis start --启动redis服务
5. redis-cli --进入redis
[root@localhost ~]# ps -ef | grep redis
root 14823 14725 0 19:41 pts/1 00:00:00 grep --color=auto redis
[root@localhost ~]# service redis start
Redirecting to /bin/systemctl start redis.service
[root@localhost ~]# ps -ef | grep redis
redis 14840 1 0 19:42 ? 00:00:00 /usr/bin/redis-server 127.0.0.1:6379
root 14844 14725 0 19:42 pts/1 00:00:00 grep --color=auto redis
[root@localhost ~]# redis-cli
127.0.0.1:6379> ?
redis-cli 3.2.12
To get help about Redis commands type:
"help @<group>" to get a list of commands in <group>
"help <command>" for help on <command>
"help <tab>" to get a list of possible help topics
"quit" to exit
To set redis-cli perferences:
":set hints" enable online hints
":set nohints" disable online hints
Set your preferences in ~/.redisclirc
6. shutdown 关闭服务
127.0.0.1:6379> shutdown SAVE not connected> not connected> Could not connect to Redis at 127.0.0.1:6379: Connection refused not connected> [root@localhost ~]# ps -ef | grep redis root 14903 14725 0 20:24 pts/1 00:00:00 grep --color=auto redis
shutdown命令后面可以跟修饰符
SAVE 和 NOSAVE 修饰符
- 通过使用可选的修饰符，可以修改 SHUTDOWN 命令的表现。比如说：
- 执行 SHUTDOWN SAVE 会强制让数据库执行保存操作，即使没有设定(configure)保存点
执行 SHUTDOWN NOSAVE 会阻止数据库执行保存操作，即使已经设定有一个或多个保存点(你可以将这一用法看作是强制停止服务器的一个假想的 ABORT 命令)
