```
Run the following command to download the XIOS source code:
Before running this command, ensure that the server can access the Internet.
Run the following commands to install the system dependency libraries:
```
yum install -y perl-lib* boost-*
```
Run the following command to switch to the directory generated after the package is decompressed:
```
cd xios-1.0
```

Run the following commands to modify the bld.cfg file:

Open bld.cfg.
```
vi bld.cfg
```

Press I to enter the insert mode and modify the bld.cfg file. Pay attention to the information in bold.

Run the following command to create and edit the arch-AARCH64_GNU_LINUX.env configuration file:
1. Create an arch-AARCH64_GNU_LINUX.env configuration file.
```
vi arch/arch-AARCH64_GNU_LINUX.env
```
2. Press i to enter the insert mode and create and edit the arch-AARCH64_GNU_LINUX.env file.
  Edit the file based on the actual environment variables and dependency library installation path.
```

Run the following commands to perform the first compilation and installation:

cd /path/to/XIOS/xios-1.0
chmod +x ./make_xios
cd extern
ln -s /path/to/BLITZ ./blitz
ln -s /path/to/NETCDF ./netcdf4
ln -s /usr/include/boost ./boost
