重启Redis缓存，拥抱新的更新（redis重启缓存更新）

Recently, Redis, as a popular key-value data storage with high performance and scalability, has been widely adopted by many companies in their applications. This is due to the fact that Redis offers extremely low latency and an easy-to-use data format with minimal mntenance overhead.

However, it is inevitable that we have to restart Redis whenever there are new updates in order to leverage the new updates. This is because, during the update process, the newly released version of Redis will replace some original functions. Therefore, only by restarting Redis can the old functions be replaced and the new functions be embraced.

Therefore, it is very important to restart Redis on a regular basis in order to ensure the most optimal performance of the application. Generally speaking, restarting Redis is very simple and the following steps show how to restart Redis on CentOS.

Step 1: Stop Redis:

With the command:

service redis stop

Step2: Cleanup Memory Allocated by Redis

Before restarting, we need to use the following command to make sure all the memory allocated by Redis is cleared.

sync && echo 3 > /proc/sys/vm/drop_caches

Step 3: Start Redis

Once Redis has been stopped, we can restart it with the command:

service redis start

By following these steps, we can easily restart Redis on CentOS. After the restart, the system will be ready to embrace the new updates and most importantly, it will guarantee that no data will be lost due to the regular restart.

In summary, restarting Redis is an important part in the Redis process and data mntenance. To ensure a consistent and optimal performance, we should always restart Redis whenever there are new updates. With the help of the above steps, everyone can easily perform the restart process and embrace the new updates.
