输入make test后
报错You need tcl 8.5 or newer in order to run the Redis test

yum install tcl

# Redis configuration file example.
#
# Note that in order to read the configuration file, Redis must be
# started with the file path as first argument:
#
# ./redis-server /path/to/redis.conf

# 启动redis
./redis-server /path/to/redis.conf # 带上配置后的redis.conf
