What is the difference between linux and aix systems

Difference: 1. Linux is an open system and can run on most hardware environments; while aix is ​​a dedicated system and must run on a proprietary hardware platform. 2. Linux is open source, but AIX is not. 3. AIX is stronger than Linux in terms of filesystem security and capacity.

#The operating environment of this tutorial: CentOS 6 system, Dell G3 computer.

The full name of AIX is (Advanced Interactive Executive), which is IBM's UNIX operating system.

Although Linux and aix are both Unix-compatible operating systems, they have their own characteristics and differences in different fields

And they all say that aix is ​​more convenient to operate. I feel that Linux is almost the same, of course it may be because I am not familiar with AIX; here are some differences I summarized.

The difference between linux and aix systems

1. Linux is an open system and can run in most hardware environments; aix is ​​a dedicated system and must run on On the proprietary hardware platform; so the biggest difference is that the supported hardware platforms are different. Linux runs on X86, and AIX is specially developed for IBM's own power architecture

2. AIX is a commercial version UNIX is a paid product. In addition to the original UNIX basic instructions of the systemV architecture, it has also developed its own management instructions. Linux is a simplified version of unix based on the systemV architecture. It is open source and you can see the source code of all instructions. Using modifications, you can also provide him with self-developed instructions for free

3. The usage of basic commands is almost the same, but there are also differences:

For example

View IP address and VLAN information

AIX: ifconfig -a, lsdev -Cc adapater and lsattr -El ent8

Linux: ifconfig and ip addr

Some aix Some commands are not available on Linux. These commands are basically related to filesytem and lvm.

For example:

lsdev, lspv, lsvg, lslv, lsfs...

chdev, chpv,chvg,...

4, LVM The level commands are a bit different, namely Disk Management.

linux First create the physical volume PV, then create the volume group VG, and then create the LV and file system. The same is true for AIX. The difference in the command: aix: createvg linux: vgcreate

5. On the file system:

AIX can directly create the file system without editing the fstab file. In AIX, you can use the smitty menu to execute the commands smitty vg smitty mklv smitty fs, etc. After entering, you can find the corresponding commands for VG, LV, and file system operations.

In addition, the PV in AIX is a disk directly recognized by the system: hdisk. You can mount as many hard drives as needed. vg can be placed on many hdisks.

And Linux needs to create pv first. It seems that AIX is stronger than Linux in terms of filesystem security and capacity.
