根据日志信息可以看出，Redis服务启动失败，错误码为217/USER。这个错误码通常是由于Redis用户没有足够的权限或者配置文件路径不正确导致的。建议您检查Redis用户的权限设置以及配置文件路径是否正确。同时，也可以通过查看更详细的日志信息来排查问题，使用命令`journalctl -xe`可以查看系统日志。

Hint: Some lines were ellipsized, use -l to show in full.发生什么事了

根据您提供的输出，看起来 Redis 服务启动失败了。错误信息为 `Failed to start redis-server`。

根据错误信息，这可能是由于 Redis 配置文件的问题导致的。建议您查看 Redis 配置文件 `/usr/local/redis/bin/redis.conf` 是否存在，以及是否存在错误的配置。您可以尝试使用以下命令启动 Redis 服务来检查 Redis 服务的启动错误信息：

sudo /usr/local/redis/bin/redis-server /usr/local/redis/bin/redis.conf

这将在终端上启动 Redis 服务，并输出错误信息。您可以参考错误信息来解决 Redis 启动失败的问题。

ln -s /lib/systemd/system/redis.service /etc/systemd/system/multi-user.target.wants/redis.service

ln -s /lib/systemd/system/redis.service /etc/systemd/system/multi-user.target.wants/redis.service命令的作用是创建一个符号链接，将/lib/systemd/system/redis.service链接到/etc/systemd/system/multi-user.target.wants/目录下的redis.service文件。这样做的目的是将redis.service服务添加到系统启动时要运行的服务列表中。通过创建这个符号链接，当系统启动时，redis服务将被自动启动。 <span class="em">1</span><span class="em">2</span><span class="em">3</span>
