Redis学习笔记（3）-XShell连接CentOSMini，并安装Redis
使用XShell远程连接CentOSMini
点击download下载XShell5.0。
下载之后安装。配置XShell。
配置XShell前的准备
打开VM，启动CentOSMini。CentOSMini启动之后进入Terminal。
[root@localhost ~]# ip addr
输入命令ip addr ，回车查看inet地址。
切换回Windows，打开CMD，输入命令ipconfig，回车查看IPv4地址。
>ipconfig
比对两个ip地址是否在同一IP段，即IP地址形式如{1}.{2}.{3}.{4}，比对1,2,3部分是否相同，相同即为同一IP段，此为XShell连通虚拟机安装的CentOSMini的前提。
配置XShell
打开XShell，点击对话->新建，弹窗如图
输入名称，自己任意起名，这里我起名CentOSMini。
主机框输入，查询到的CentOSMini的inet地址。
端口号，默认22，如果端口被占用可能导致连接失败。
点击用户身份验证，输入CentOSMini的账户和密码
配置完成，尝试连接。如果连接失败，请自行排查原因。
默认连接成功，开始安装Redis。
安转Redis
以下配置，默认用户都未完成，如果已经完成，再次执行不会有影响。
加载插件gcc
[root@localhost ~]# yum gcc
加载插件wget
[root@localhost ~]# yum wget
下载及安装Redis
Redis安装包网址
最新的安装包为redis-3.0.7.tar.gz
[root@localhost ~]#wget http://download.redis.io/releases/redis-3.0.7.tar.gz [root@localhost ~]#tar zxvf redis-3.0.7.tar.gz [root@localhost ~]# cd redis-3.0.7 [root@localhost redis-3.0.7]# make MALLOC=libc
启动Redis
[root@localhost redis-3.0.7]# src/redis-server 14891:C 27 Apr 13:10:08.132 # Warning: no config file specified, using the default config.

测试Redis
在XShell，打开一个新的终端标签
[root@localhost ~]# ls anaconda-ks.cfg redis-3.0.7 redis-3.0.7.tar.gz [root@localhost ~]# cd redis-3.0.7 [root@localhost redis-3.0.7]# src/redis-cli 127.0.0.1:6379> KEYS * 1) "user:1" 2) "test" 3) "Manager" 4) "name" 127.0.0.1:6379>
退出Redis命令行
[root@localhost redis-3.0.7]# src/redis-cli 127.0.0.1:6379> quit [root@localhost redis-3.0.7]#
关闭Redis
Redis命令行下
[root@localhost redis-3.0.7]# src/redis-cli 127.0.0.1:6379> shutdown
非Redis命令行下
[root@localhost redis-3.0.7]# src/redis-cli shutdown
