Ubuntu16.04安装并配置Redis

1. 安装Redis服务器端

~ sudo apt-get install redis-server

安装完成后，Redis服务器会自动启动，我们检查Redis服务器程序

2. 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

3.1 检查Redis服务器状态 法1：

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

3.2 检查Redis服务器状态 法2：

~$ sudo /etc/init.d/redis-server status
● redis-server.service - Advanced key-value store
   Loaded: loaded (/lib/systemd/system/redis-server.service; enabled; vendor preset: enabled)

4. 通过命令行客户端访问Redis

安装Redis服务器，会自动地一起安装Redis命令行客户端程序。
在本机输入redis-cli命令就可以启动，客户端程序访问Redis服务器。

~ redis-cli
redis 127.0.0.1:6379>

# 命令行的帮助
redis 127.0.0.1:6379> help
redis-cli 2.2.12
Type: "help @" to get a list of commands in 
      "help " for help on 
      "help " to get a list of possible help topics
      "quit" to exit


# 查看所有的key列表
redis 127.0.0.1:6379> keys *
(empty list or set)

5. 修改Redis的配置

~ sudo vi /etc/redis/redis.conf
……修改完成
~ sudo /etc/init.d/redis-server start

# 5.1 取消注释requirepass，设置密码
requirepass password

# 5.2 注释bind，让Redis服务器被远程访问
#bind 127.0.0.1

# 修改后，重启Redis服务器。
~ sudo /etc/init.d/redis-server restart
