Ubuntu16.04.3安装Reids

    Redis是常用基于内存的Key-Value数据库，比Memcache更先进，支持多种数据结构，高效，快速。用Redis可以很轻松解决高并发的数据访问问题；作为实时监控信号处理也非常不错。

环境

Ubuntu16.04.3

安装Redis服务器端

sudo apt-get -y install redis-server

检查Redis服务器系统进程

~ ps -aux|grep redis
redis     4162  0.1  0.0  10676  1420 ?    Ss   23:24   0:00 /usr/bin/redis-server /etc/redis/redis.conf
conan     4172  0.0  0.0  11064   924 pts/0    S+   23:26   0:00 grep --color=auto redis

通过启动命令检查Redis服务器状态

~ netstat -nlt|grep 6379
tcp        0      0 127.0.0.1:6379          0.0.0.0:*               LISTEN

查看Reids服务状态

root@iZ2ze1lytcrrmr1shasmx4Z:/home/soft# netstat -nlt | grep 6379
tcp        0      0 127.0.0.1:6379          0.0.0.0:*               LISTEN

通过命令行客户端访问Redis

root@iZ2ze1lytcrrmr1shasmx4Z:/home/soft# redis-cli
127.0.0.1:6379> 

配置远程连接

找到/etc/redis/redis.conf文件，注释bind 127.0.0.1

为了安全设置密码

找到/etc/redis/redis.conf文件
找到requirepass foobared解注释
foodared即为当前密码

重启服务

/etc/init.d/redis-server restart
