How to install “rsync” con CentOS 7?<\/h2>\n\n\n\n
The installation of “rsync” is really easy, either using the “root” account or another user with “sudo” privileges, you can use the following CLI command.<\/p>\n\n\n
yum install rsync<\/p>\n\n\n
The installation speed depends on the contracted Internet Speed but also depends on how close you are located to the repository containing the software, the following animations shows the whole installation process.<\/p>\n\n\n\n

This option increases the amount of information you are given during the transfer, by default, rsync works silently. A single -v will give you information about what files are being transferred and a brief summary at the end.<\/p>\n\n\n\nWordPress and rsync<\/h2>\n\n\n\n
A good use case for “rsync” could be when installing WordPress, let’s say you’ve downloaded the latest WordPress version from the official website and after decompressing the file into your home directory, now you have to copy them to their final destination in that case you can use “rsync” as follow:<\/p>\n\n\n
rsync -avP ~\/wordpress\/ \/var\/www\/html\/<\/strong> <\/p>\n\n\nThe destination folder of the above command applies to cases where Apache is not configured to use Virtual Hosts, if you want to learn about Apache and Virtual Host you can take a look at this article.<\/a><\/p>\n\n\n\nWhere was “rsync” installed?<\/h2>\n\n\n\n
Aren’t you curious about where in your system was “rsync” installed, if so here you are a few CLI command which can assist you.<\/p>\n\n\n
