单位memcached.安装memcached时，在Ubunto 20.04上找不到服务

Question

我试图按照这些说明在Ubuntu 20.04的Vultr上安装memcached，但是当我到达步骤sudo make install时，输出是:

make  all-recursive
make[1]: Entering directory '/root/memcached-1.6.17'
Making all in doc
make[2]: Entering directory '/root/memcached-1.6.17/doc'

make[3]: Entering directory '/root/memcached-1.6.17/doc'
make[3]: Nothing to be done for 'all-am'.
make[3]: Leaving directory '/root/memcached-1.6.17/doc'

/usr/bin/install -c -m 644 protocol_binary.h xxhash.h '/usr/local/memcached/include/memcached'
make[3]: Leaving directory '/root/memcached-1.6.17'
make[2]: Leaving directory '/root/memcached-1.6.17'
make[1]: Leaving directory '/root/memcached-1.6.17'

然后试图启动memcached:

sudo systemctl start memcached

导致Failed to start memcached.service: Unit memcached.service not found.

我在这里错过了什么?

(Vultr还指示"测试Memcached是否激活并在TCP端口11211上运行";通过运行netstat -tulpn | grep :11211——当我第一次尝试这样做时，我必须安装netstat，但是运行这个命令没有任何作用。)

由于您是从源代码安装了memcached，因此您需要直接从命令行运行二进制文件来启动服务。

/usr/local/memcached/bin/memcached -d -m 64 -l 127.0.0.1 -p 11211
