go 中使用redis 基础用法
1、安装redis
参考链接：https://www.codeleading.com/article/98554130215/
1.1 查看是否有redis yum 源
yum install redis
没有可用的软件包，执行1.2
1.2下载fedora的epel仓库
yum install epel-release --下载fedora的epel仓库
1.3启动redis
service redis start
systemctl start redis.service --开启redis服务
1.4 ps -ef | grep redis – 查看redis是否开启
1.5 redis-cli – 进入redis服务
[root@localhost ~]# redis-cli
127.0.0.1:6379> ?
redis-cli 3.2.10
To get help about Redis commands type:
"help @<group>" to get a list of commands in <group>
"help <command>" for help on <command>
"help <tab>" to get a list of possible help topics
"quit" to exit
To set redis-cli perferences:
":set hints" enable online hints
":set nohints" disable online hints
Set your preferences in ~/.redisclirc
127.0.0.1:6379> get
(error) ERR wrong number of arguments for 'get' command
127.0.0.1:6379> get key
(nil)
127.0.0.1:6379> get key abc
(error) ERR wrong number of arguments for 'get' command
127.0.0.1:6379> set key abc
OK
127.0.0.1:6379> get key abc
(error) ERR wrong number of arguments for 'get' command
127.0.0.1:6379> get key
"abc"
127.0.0.1:6379>
1.6 redis-cli shutdown --关闭服务
[root@localhost ~]# redis-cli
127.0.0.1:6379> shutdown
not connected>
not connected>
[root@localhost ~]# ps -ef |grep redis
root 5127 4497 0 08:34 pts/0 00:00:00 grep --color=auto redis
[root@localhost ~]# systemctl start redis.service
[root@localhost ~]# ps -ef |grep redis
redis 5134 1 0 08:34 ? 00:00:00 /usr/bin/redis-server 127.0.0.1:6379
root 5138 4497 0 08:35 pts/0 00:00:00 grep --color=auto redis
[root@localhost ~]#
1.7、开放端口6379、6380的防火墙
/sbin/iptables -I INPUT -p tcp --dport 6379 -j ACCEPT 开启6379
/sbin/iptables -I INPUT -p tcp --dport 6380 -j ACCEPT 开启6380
[root@localhost ~]# /sbin/iptables -I INPUT -p tcp --dport 6379 -j ACCEPT
[root@localhost ~]# /sbin/iptables -I INPUT -p tcp --dport 6380 -j ACCEPT
