### CentOS 7
|
||||
|
||||
当使用CentOS 7时，需要安装由ELRepo Project提供的新版Linux内核。可以在[这个页面](http://elrepo.org/tiki/kernel-ml)找到有关ELRepo Project提供的Linux内核的更多信息。
|
||||
|
||||
参见下面的安装说明。
|
||||
|
||||
1. 导入ELRepo Project的公钥。
|
||||
```bash
|
||||
sudo rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org
|
||||
```
|
||||
2. 为 RHEL-7、SL-7 或 CentOS-7 安装 ELRepo。
|
||||
```bash
|
||||
sudo yum install https://www.elrepo.org/elrepo-release-7.el7.elrepo.noarch.rpm
|
||||
```
|
||||
3. 安装 `kernel-ml`。
|
||||
```bash
|
||||
sudo yum --enablerepo=elrepo-kernel install kernel-ml
|
||||
```
|
||||
4. 确认结果。
|
||||
```bash
|
||||
rpm -qa | grep kernel
|
||||
```
|
||||
你应该在输出中看到 `kernel-ml-xxx`。
|
||||
5. 显示 grub2 菜单中的所有条目并设置 `kernel-ml`。
|
||||
```bash
|
||||
sudo egrep ^menuentry /etc/grub2.cfg | cut -f 2 -d \'
|
||||
```
|
||||
**索引从 `0` 开始。**
|
||||
例如，当 `kernel-ml` 位于 `1` 时，使用下面的命令来激活 `kernel-ml`。
|
||||
```bash
|
||||
sudo grub2-set-default 1
|
||||
```
|
||||
6. 重启。
|
||||
```bash
|
||||
sudo reboot
|
||||
```
|
||||
7. 检查 Linux 内核版本。
|
||||
```bash
|
||||
uname -r
|
||||
```

### CentOS 7
|
||||
|
||||
When using CentOS 7, a newer Linux kernel provided by the ELRepo Project needs to be installed. More information about the Linux kernels provided by the ELRepo Project can be found at [this page](http://elrepo.org/tiki/kernel-ml).
|
||||
|
||||
Refer to the installation instructions below.
|
||||
|
||||
1. Import ELRepo Project's public key.
|
||||
```bash
|
||||
sudo rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org
|
||||
```
|
||||
2. Install ELRepo for RHEL-7, SL-7 or CentOS-7.
|
||||
```bash
|
||||
sudo yum install https://www.elrepo.org/elrepo-release-7.el7.elrepo.noarch.rpm
|
||||
```
|
||||
3. Install `kernel-ml`.
|
||||
```bash
|
||||
sudo yum --enablerepo=elrepo-kernel install kernel-ml
|
||||
```
|
||||
4. Confirm the result.
|
||||
```bash
|
||||
rpm -qa | grep kernel
|
||||
```
|
||||
You should see `kernel-ml-xxx` in output.
|
||||
5. Show all entries in the grub2 menu and setup `kernel-ml`.
|
||||
```bash
|
||||
sudo egrep ^menuentry /etc/grub2.cfg | cut -f 2 -d \'
|
||||
```
|
||||
**Indexing starts at `0`.**
|
||||
For example, when the `kernel-ml` is located at `1`, use the command below to activate `kernel-ml`.
|
||||
```bash
|
||||
sudo grub2-set-default 1
|
||||
```
|
||||
6. Reboot.
|
||||
```bash
|
||||
sudo reboot
|
||||
```
|
||||
7. Check Linux kernel version.
|
||||
```bash
|
||||
uname -r
|
||||
```
