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..tar.gz
[root@localhost ~]# cd redis-3.0.
[root@localhost redis-3.0.]# make MALLOC=libc

启动Redis

测试Redis

在XShell，打开一个新的终端标签

[root@localhost ~]# ls
anaconda-ks.cfg  redis-3.0.  redis-3.0..tar.gz
[root@localhost ~]# cd redis-3.0.
[root@localhost redis-3.0.]# src/redis-cli
127.0.0.1:> KEYS *
) "user:1"
) "test"
) "Manager"
) "name"
127.0.0.1:> 

退出Redis命令行

[root@localhost redis-3.0.]# src/redis-cli
127.0.0.1:> quit
[root@localhost redis-3.0.]# 

关闭Redis

Redis命令行下

[root@localhost redis-3.0.]# src/redis-cli
127.0.0.1:> shutdown

非Redis命令行下

[root@localhost redis-3.0.]# src/redis-cli shutdown
