redis介绍不再累赘
1、安装gcc,因为Redis是用C语言写的,所以需要gcc进行编译
yum install gcc -y
2、下载redis-2.8.9.tar.gz
http://download.redis.io/releases/redis-2.8.9.tar.gz
3、安装Redis
tar xf redis-2.8.9.tar.gz
cd redis-2.8.9
make MALLOC=libc
make PREFIX=/usr/local/redis install
4、安装完成以后查看目录以及文件
[root@salt-server bin]# pwd
/usr/local/redis/bin
[root@salt-server bin]# ls
redis-benchmark redis-check-aof redis-check-dump redis-cli redis-server
5、命令解释
redis-server:redis服务器的daemon启动程序
redis-cli:redis命令行操作工具
redis-benchmark:redis性能测试工具
redis-check-aof:对更新日志appendonly.aof检查
redis-check-dump:用于本地数据库rdb文件的检查
6、配置启动服务
设置环境变量:
vim /etc/profile
PATH=$PATH:/usr/local/redis/bin
source /etc/profile
拷贝配置文件:
mkdir /usr/local/redis/conf
cp redis-2.8.9/redis.conf /usr/local/redis/conf
echo "vm.overcommit_memory = 1" >> /etc/sysctl.conf && sysctl -p
启动服务:redis-server /usr/local/redis/conf/redis.conf &
7、启动成功正常反馈如下
[root@salt-server ~]# redis-server /usr/local/redis/conf/redis.conf &
[1] 11736
[root@salt-server ~]# [11736] 27 Jan 09:16:07.772 * Increased maximum number of open files to 10032 (it was originally set to 1024).

[11736] 27 Jan 09:16:07.773 # Server started, Redis version 2.8.9
[11736] 27 Jan 09:16:07.773 * The server is now ready to accept connections on port 6379
8、基本操作
关闭redis:redis-cli shutdown
可直接输入redis-cli进去交互式
[root@salt-client1 ~]# redis-cli
127.0.0.1:6379>
输入值并取值测试
[root@salt-client1 ~]# redis-cli
127.0.0.1:6379> set Test 001 //设置一个Test值为001
OK
127.0.0.1:6379> get Test //获取Test的值
"001"
127.0.0.1:6379> del Test //删除一个值
(integer) 1
127.0.0.1:6379>keys * //取所有值
9、客户端连接使用
[root@salt-client1 ~]# redis-cli -h 172.16.10.133 -p 6379
172.16.10.133:6379>
也可以不登录直接赋值
[root@salt-client1 ~]# redis-cli -h 172.16.10.133 -p 6379 set Test 789
OK
[root@salt-client1 ~]# redis-cli -h 172.16.10.133 -p 6379 get Test
"789"
10、redis安全
为redis客户端设置外部连接密码
vim /usr/local/redis/conf/redis.conf
修改requirepass如下:
requirepass a)s$M7F57TN58$8
重启redis
redis-cli shutdown
redis-server /usr/local/redis/conf/redis.conf &
直接登录测试会提示认证失败需要指定密码
[root@salt-server ~]# redis-cli
127.0.0.1:6379> set d 1
(error) NOAUTH Authentication required.
127.0.0.1:6379>
指定密码登录
[root@salt-server ~]# redis-cli
127.0.0.1:6379> auth a)s$M7F57TN58$8
OK
