我是靠谱客的博主超帅冷风，这篇文章主要介绍单台机器redis多实例单台机器redis多实例，现在分享给大家，希望可以做个参考。

单台机器redis多实例

redis作为缓冲、验证码数据库非常好用，但redsi是单线程的，如果通过rpm工具安装的话，一台机器只能安装一个实例，如果有多个实例，需要部署多台机器上；下面脚本就实现了，一台机器安装5个redis，每个redis端口都不一样；端口从16379开始。

复制代码

# 告诉bash如果任何语句的执行结果不是true则应该退出

source ~/.bash_profile
# 获取脚本所在的目录名称，并进入该目录
DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"
echo "$DIR"
cd $DIR/pkg
# 把redis制作成服务
