[TOC] # redis啟動 Redis啟動的時候，可以指定配置文件，如下： ~~~ /usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf & ~~~ 注：#加上&號使redis以后臺程序方式運行 # 外網連不上redis ~~~ vim redis.conf ~~~ 把里面的bind 127.0.0.1前面加個# 注釋掉,這個可能不止一行,關于這個的全部注釋掉,外面的網就可以連接成功了 設置密碼 為了安全一定要設，而且這里如果不綁定ip也不設密碼的話，redis是默認保護模式，只能本虛擬機訪問，不允許其他ip訪問，本人剛開始圖方便啥都不設，結果在這里踩坑了 .還有linux的防火墻開放端口還有aliyun的安全組 在配置文件里面設置requirepass 重啟redis ~~~ # service不行就用systemctl sudo service redis restart ~~~ 在redis3.2之后，redis增加了protected-mode，在這個模式下，即使注釋掉了bind 127.0.0.1，再訪問redisd時候還是報錯，如下 ~~~ (error) DENIED Redis is running in protected mode because protected mode is enabled, no bind address was specified, no authentication password is requested to clients. In this mode connections are only accepted from the loopback interface. If you want to connect from external computers to Redis you may adopt one of the following solutions: 1) Just disable protected mode sending the command 'CONFIG SET protected-mode no' from the loopback interface by connecting to Redis from the same host the server is running, however MAKE SURE Redis is not publicly accessible from internet if you do so. Use CONFIG REWRITE to make this change permanent. 2) Alternatively you can just disable the protected mode by editing the Redis configuration file, and setting the protected mode option to 'no', and then restarting the server. 3) If you started the server manually just for testing, restart it with the '--protected-mode no' option. 4) Setup a bind address or an authentication password. NOTE: You only need to do one of the above things in order for the server to start accepting connections from the outside. ~~~ 修改辦法,修改配置文件：protected-mode no
