centos 6.8安装Redis和简单的使用
一、安装依赖包，准备环境。
yum install -y gcc
依赖包情况可能会不一样，按照编译时候的提示安装就可以了。但是gcc一定要装。
二、下载安装
1、下载tar包,安装启动。
wget http://source.goyun.org:8000/source/Redis/redis-3.2.9.tar.gz
--2018-01-12 19:15:07-- http://source.goyun.org:8000/source/Redis/redis-3.2.9.tar.gz

100%[===================================================================================================================>] 1,547,695 73.8K/s in 42s
2018-01-12 19:15:49 (36.4 KB/s) - “redis-3.2.9.tar.gz.1” saved [1547695/1547695]
默认是下载在当前目录下的，
2、解压：
tar zxvf redis-3.2.9.tar.gz
[root@localhost ~]# ll
drwxrwxr-x 6 root root 4096 May 17 2017 redis-3.2.9
-rw-r--r-- 1 root root 1547695 Jan 12 15:07 redis-3.2.9.tar.gz
会在当前目录下面产生一个redis-3.2.9目录。
3、进入目录并make：
[root@localhost ~]# cd redis-3.2.9
[root@localhost redis-3.2.9]# ll

drwxrwxr-x 7 root root 4096 May 17 2017 utils
[root@localhost redis-3.2.9]# make
4、进入解压的目录下：
[root@localhost redis-3.2.9]# cd src/
[root@localhost src]# pwd
/root/redis-3.2.9/src
[root@localhost src]#make test
You need tcl 8.5 or newer in order to run the Redis test
make: *** [test] Error 1
注意，注意，这里出现报错，解决的办法：下载并安装TCL
[root@localhost src]#cd
[root@localhost ~]#wget http://downloads.sourceforge.net/tcl/tcl8.6.1-src.tar.gz
[root@localhost ~]# ll
drwxrwxr-x 6 root root 4096 May 17 2017 redis-3.2.9
-rw-r--r-- 1 root root 1547695 Jan 12 15:07 redis-3.2.9.tar.gz
-rw-r--r-- 1 root root 229376 Jan 12 19:25 tcl8.6.1-src.tar.gz
[root@localhost ~]# tar zxvf tcl8.6.1-src.tar.gz
[root@localhost ~]# ll
drwxrwxr-x 6 root root 4096 May 17 2017 redis-3.2.9
-rw-r--r-- 1 root root 1547695 Jan 12 15:07 redis-3.2.9.tar.gz
-rw-r--r-- 1 root root 229376 Jan 12 19:25 tcl8.6.1-src.tar.gz
drwxr-xr-x 4 15399 19249 4096 Sep 20 2013 tcl8.6.1
[root@localhost Desktop]# cd tcl8.6.1/
[root@localhost tcl8.6.1]# cd unix/
[root@localhost unix]# ./configure
[root@localhost unix]# make && make install
5、回到Redis的假牙目录再次make test
[root@localhost src]# pwd
/root/redis-3.2.9/src
显示 All tests passed without errors !
就是测试成功啦！
可以安装了。
6、安装：
[root@localhost src]# make PREFIX=/usr/local/redis install
[root@loalhost redis]# cd /usr/local/redis
[root@loalhost redis]# ll
total 56
drwxr-xr-x 2 root root 4096 Jan 12 15:52 bin
-rw-r--r-- 1 root root 90 Jan 12 16:34 dump.rdb
[root@loalhost redis]# cd bin/
[root@loalhost bin]# ls
dump.rdb redis-check-aof redis-cli redis-server
redis-benchmark redis-check-rdb redis-sentinel
7、把解压的redis路径下的redis.conf文件拷贝到安装路径下面
[root@localhost ~]# cd redis-3.2.9
[root@localhost redis-3.2.9]# ll
total 208
-rw-rw-r-- 1 root root 87407 May 17 2017 00-RELEASENOTES
-rw-rw-r-- 1 root root 53 May 17 2017 BUGS
-rw-rw-r-- 1 root root 1805 May 17 2017 CONTRIBUTING
-rw-rw-r-- 1 root root 1487 May 17 2017 COPYING
drwxrwxr-x 7 root root 4096 Jan 12 19:21 deps
-rw-rw-r-- 1 root root 11 May 17 2017 INSTALL
-rw-rw-r-- 1 root root 151 May 17 2017 Makefile
-rw-rw-r-- 1 root root 4223 May 17 2017 MANIFESTO

-rwxrwxr-x 1 root root 271 May 17 2017 runtest
-rwxrwxr-x 1 root root 280 May 17 2017 runtest-cluster
-rwxrwxr-x 1 root root 281 May 17 2017 runtest-sentinel
-rw-rw-r-- 1 root root 7606 May 17 2017 sentinel.conf
drwxrwxr-x 2 root root 4096 Jan 12 19:22 src
drwxrwxr-x 10 root root 4096 May 17 2017 tests
drwxrwxr-x 7 root root 4096 May 17 2017 utils
[root@localhost redis-3.2.9]# cp redis.conf /usr/local/redis
[root@localhost local]# cd /usr/local/redis
[root@localhost redis]# ll
total 56
drwxr-xr-x 2 root root 4096 Jan 12 15:52 bin
-rw-r--r-- 1 root root 90 Jan 12 16:34 dump.rdb
-rw-r--r-- 1 root root 46696 Jan 12 15:53 redis.conf
[root@localhost redis]# cd bin/
[root@localhost bin]# ls
dump.rdb redis-check-aof redis-cli redis-server
redis-benchmark redis-check-rdb redis-sentinel
8、启动Redis
第一种方法：
[root@localhost bin]# ./redis-server
会显示下面的样子：
[root@server51 bin]# ./redis-server
38210:C 12 Jan 18:01:18.469 # Warning: no config file specified, using the default config. In order to specify a config file use ./redis-server /path/to/redis.conf
38210:M 12 Jan 18:01:18.472 * Increased maximum number of open files to 10032 (it was originally set to 1024).

38210:M 12 Jan 18:01:18.513 * The server is now ready to accept connections on port 6379
这样其实已经启动成功了，但是这属于前端启动，启动redis之后，我们的控制台就不能进行任何操作了。只能ctrl+c停止启动。
第二种方法：
后端启动
首先编辑redis.conf
[root@localhost redis]# vim redis.conf
找到daemonize no将其改为yes
再次启动
[root@localhost redis]# ./bin/redis-server ./redis.conf
//这里加载配置文件
80167:C 30 Jul 16:01:58.145 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
80167:C 30 Jul 16:01:58.145 # Redis version=4.0.1, bits=64, commit=00000000, modified=0, pid=80167, just started
80167:C 30 Jul 16:01:58.145 # Configuration loaded
可以查看进程：
[root@localhost bin]# ps -ef | grep -i redis
root 130477 1 0 19:51 ? 00:00:00 ./bin/redis-server 127.0.0.1:6379
root 130559 130412 0 19:58 pts/0 00:00:00 grep -i redis
说明启动了。
关闭Redis的命令：
[root@localhost redis]# ./bin/redis-cli shutdown
三、简单的使用：
[root@localhost redis]# ./bin/redis-cli
//检查网络是否可以
127.0.0.1:6379> ping
PONG
//设置一个键值对
127.0.0.1:6379> set name xiaoyao
OK
//获取刚刚设置的键值对
127.0.0.1:6379> get name
"xiaoyao"
//查看所有的键
127.0.0.1:6379> keys *
1) "name"
//删除name这个键
127.0.0.1:6379> del name
(integer) 1
127.0.0.1:6379> keys *
(empty list or set)
127.0.0.1:6379>
