# 设置密码，开启远程访问redis

# 修改 /data/redis/etc/redis.conf

# 找到以下行：

# #requirepass

# 去掉注释 # ，并设置密码：

# requirepass newpassword

# 将：

# protected-mode yes

# 改为：

# protected-mode no

# 将：

# bind 127.0.0.1

# 注释掉，或者者改为：

# bind 0.0.0.0

# 启动服务

service redis start

# 本机访问，需要输入密码：

/data/redis/bin/redis-cli
