一、redis安装教程
1.安装redis
~]# yum -y install gcc gcc-c++ make
~]# tar -xf redis-4.0.8.tar.gz
~]# cd redis-4.0.8/ redis-4.0.8]# ls00-RELEASENOTES COPYING Makefile redis.conf runtest-sentinel tests
BUGS deps MANIFESTO runtest sentinel.conf utils
CONTRIBUTING INSTALL README.md runtest-cluster src
redis-4.0.8]# make && make install
redis-4.0.8]# cd utils/utils]# ./install_server.sh
Welcome to the redis service installer
This script will help you easily set up a running redis server
Please selectthe redis portforthisinstance: [6379]
Selecting default:6379Please selectthe redis config file name [/etc/redis/6379.conf]
Selected default- /etc/redis/6379.conf
Please selectthe redis log file name [/var/log/redis_6379.log]
Selected default- /var/log/redis_6379.log
Please selectthe data directoryforthisinstance [/var/lib/redis/6379]
Selected default- /var/lib/redis/6379Please selectthe redis executable path [/usr/local/bin/redis-server]
Selected config:
Port : 6379Config file : /etc/redis/6379.conf
Log file : /var/log/redis_6379.log
Data dir : /var/lib/redis/6379Executable : /usr/local/bin/redis-server
Cli Executable : /usr/local/bin/redis-cli
Is thisok? Then press ENTER to go on or Ctrl-C to abort.
Copied /tmp/6379.conf => /etc/init.d/redis_6379
Installing service...
Successfully added to chkconfig!Successfully added to runlevels 345!Starting Redis server...
Installation successful!
2.查看状态
]# /etc/init.d/redis_6379 status
Redis isrunning (9485)
3.查看监听端口
utils]# netstat -utnlp | grep6379tcp 00127.0.0.1:63790.0.0.0:* LISTEN9485/redis-server1utils]# ps -C resis-server1 PID TTY STAT TIME COMMAND
1? Ss0:06/usr/lib/systemd/systemd --switched-root --system --deserialize21
4.停止服务
utils]# /etc/init.d/redis_6379 stop
Stopping ...
Redis stopped
[root@haproxy utils]# /etc/init.d/redis_6379 status
cat: /var/run/redis_6379.pid: 没有那个文件或目录
Redis isrunning ()
5.连接redis
utils]# /etc/init.d/redis_6379 start
Starting Redis server...
[root@haproxy utils]# redis-cli
127.0.0.1:6379> ping
PONG //PONG说明服务正常
6.redis应用
1】设置变量test，值为123，查看变量test值
常用指令操作：
Set keyname keyvalue存储
get keyname 获取
127.0.0.1:6379>set test 123
OK127.0.0.1:6379>get test"123"
2】删除变量
del keyname 删除变量
127.0.0.1:6379>set k1 v1
OK
127.0.0.1:6379>get k1 "v1"
127.0.0.1:6379> del k1
(integer) 1
3】打印所有变量
Keys * 打印所有变量
127.0.0.1:6379> keys *
1)"k1"
2)"test"
4】测试是否存在
EXISTS keyname 测试是否存在
127.0.0.1:6379> exists k1
(integer) 0
5】查看类型
type keyname 查看类型
127.0.0.1:6379>set k2 v1
OK127.0.0.1:6379> type k2
string
6】移动变量
move keyname dbname 移动变量
127.0.0.1:6379> move k2 1 //移动k2到1库
(integer) 1
7】 切换库
Select 数据库编号0-15 切换库
127.0.0.1:6379>select 1 //切换到1库
OK
127.0.0.1:6379[1]> keys * //查看有k2
1)"k2"
8】设置有效时间
expire keyname 10 设置有效时间
127.0.0.1:6379[1]> expire k2 10
(integer) 1
9】查看生存时间
ttl keyname 查看生存时间
127.0.0.1:6379[1]> ttl k2
(integer) -2
10】删除所有变量
flushall 删除所有变量
127.0.0.1:6379[1]> flushall
OK127.0.0.1:6379[1]> keys *
(empty list or set)
11】保存所有变量
Save 保存所有变量
127.0.0.1:6379[1]> save
OK
12】关闭redis服务
Shutdown 关闭redis服务
127.0.0.1:6379[1]> shutdown
not connected>
二、修改redis运行参数
1】修改配置文件
utils]# cp /etc/redis/6379.conf /root/6379.conf//备份一份。避免改错无法还原
utils]# /etc/init.d/redis_6379 stop
utils]# vim /etc/redis/6379.conf
70bind192.168.4.50//设置服务使用的IP93port6351//更改端口号502requirepass123456//设置密码
utils]# ss -antul | grep6351tcp LISTEN 0128192.168.4.50:6351*:*
2.由于修改了配置文件所以在连接的时候需要加上IP和端口
utils]# redis-cli -h192.168.4.50-p6351192.168.4.50:6351> ping
(error) NOAUTH Authentication required.
192.168.4.50:6351> auth 123456 //输入密码才能操作（因为配置文件设置了密码）
OK
192.168.4.50:6351> ping
PONG
3.也可以直接在命令行输入密码连接
utils]# redis-cli -h 192.168.4.50 -p 6351 -a 123456
192.168.4.50:6351> ping
PONG
2】停止服务
由于修改redis服务运行参数，所以在停止服务的时候也不能用默认的方法停止
utils]# /etc/init.d/redis_6379 stop
Stopping ...
Could not connect to Redis at 127.0.0.1:6379: Connection refused
Waiting for Redis to shutdown ...
Waiting for Redis to shutdown ...
Waiting for Redis to shutdown ...
.......
utils]# redis-cli -h 192.168.4.50 -p 6351 -a 123456 shutdown //停止成功
[root@haproxy utils]# ss -antul | grep 6351 //查看没有端口
