Mac上安装Redis遇到问题 Mmmmm... the default config is missing. Did you switch to the utils directory?

1. Mac上安装Redis，把Redis安装成服务，运行【sudo ./install_server.sh】时遇到问题：
        Mmmmm... the default config is missing. Did you switch to the utils directory?

原因：Mac不识别install_server.sh中readlink命令，所以无法找到默认配置文件redis.conf在哪儿（其实就在上一层目录里）

解决：方案一：根据这位博主的方法，使用greadlink命令代替readlink

           方案二：将install_server.sh中

#Absolute path to this script
SCRIPT=$(readlink -f $0)
#Absolute path this script is in
SCRIPTPATH=$(dirname $SCRIPT)

修改为

#Absolute path this script is in
SCRIPTPATH=$(cd `dirname $0`; pwd)

2. 接下来果运行会出现错误：

      ./install_server.sh: line 275: /etc/init.d/redis_6379: No such file or directory

原因：Mac中启动文件不在/etc/init.d

解决：我选择不开机启动，注释掉install_server.sh下面两个部分即可

#copy to /etc/init.d
cp $TMP_FILE $INIT_SCRIPT_DEST && \
	chmod +x $INIT_SCRIPT_DEST || die "Could not copy redis init script to $INIT_SCRIPT_DEST"
echo "Copied $TMP_FILE => $INIT_SCRIPT_DEST"

/etc/init.d/redis_$REDIS_PORT start || die "Failed starting service..."
