I tried to find another foreign server to do the Nginx reverse proxy, but SES itself will verify the SSL certificate, so the experiment is not successful. I wonder if you have a good solution? Other services are not considered for the time being, because other than this one is very comfortable to use.

compared with the desktop, we have a relatively low demand for notebook performance, so in the process of upgrading the notebook hard drive is the pursuit of performance or large capacity, or both? Small series will come up with three solutions to discuss with you.
For the different needs of the user groups, we will be the notebook upgrade program roughly summed up in the following three kinds:

When SSD is optimized,/var/log is placed in the ramdisk of tmpfs. restart causes the apache2 and nginx directories in/var/log to be lost, and apache2/nginx cannot be started.
Solution: in ~ /. Create these two directories in ~ /. Add at the end of bashrc. (Oh, use
The biggest difference between SSD and HDD is that it does not have the necessary mechanical parts of the HDD, the disc, the head rocker arm, which is determined by the different working principle of two kinds of hard drives. SSDs save time in mechanical parts movement compared to HDDs, and the primary storage element NAND flash used by SSDs is an electronic component, so its data travels much faster than HDD.In addition, according to the test, the HD
