Installation Containerd-1.6.5 CentOS 7.9

一、Installation Containerd-1.6.5 CentOS 7.9

地址

在containerd前，需要优先升级libseccomp。

在CentOS 7中yum下载libseccomp的版本是2.3的，版本不满足最新 Containerd 的需求，需要下载2.4以上的。

 

二、Upgrading libseccomp-2.5.1 on CentOS 7.9

地址

卸载原来的

[root@ecs-65685 ~]# rpm -qa | grep libseccomp
libseccomp-2.3.1-4.el7.x86_64
[root@ecs-65685 ~]# 
[root@ecs-65685 ~]# rpm -e libseccomp-2.3.1-4.el7.x86_64 --nodeps

CentOS 8.2 默认2.5.1，可以不用更新

wget下载

wget https://rpmfind.net/linux/centos/8-stream/BaseOS/x86_64/os/Packages/libseccomp-2.5.1-1.el8.x86_64.rpm
wget https://rpmfind.net/linux/centos/8-stream/BaseOS/x86_64/os/Packages/libseccomp-2.5.2-1.el8.x86_64.rpm

安装 libseccomp

[root@ecs-65685 software]# rpm -ivh /opt/software/libseccomp-2.5.1-1.el8.x86_64.rpm 
warning: /opt/software/libseccomp-2.5.1-1.el8.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID 8483c65d: NOKEY

   1:libseccomp-2.5.1-1.el8           ################################# [100%]

查看当前版本

[root@ecs-65685 software]# rpm -qa | grep libseccomp
libseccomp-2.5.1-1.el8.x86_64

注意：使用场景在 Kubernetes 1.24+版本中的Containerd会用到。

 

三、下载安装 Containerd

1 官方地址：https://containerd.io/downloads

Containerd安装我们使用1.6.4以上的版本号。

containerd-1.6.1-linux-amd64.tar.gz 只包含 containerd。

cri-containerd-cni-1.6.5-linux-amd64.tar.gz 包含containerd以及 cri runc 等相关工具包，建议下载本包。

wget https://github.com/containerd/containerd/releases/download/v1.6.5/cri-containerd-cni-1.6.5-linux-amd64.tar.gz

2 解压

# 对应的目录给替换掉
[root@ecs-65685 software]# tar -zxvf /opt/software/cri-containerd-cni-1.6.5-linux-amd64.tar.gz -C /
etc/
etc/cni/
etc/cni/net.d/

opt/containerd/cluster/gce/configure.sh
opt/containerd/cluster/gce/cni.template
opt/containerd/cluster/gce/env
opt/containerd/cluster/version

cri-containerd-cni会将我们整个containerd相关的依赖都进行下载下来。

上面的文件都是二进制文件，直接移动到对应的目录并配置好环境变量就可以进行使用了。

 

四、安装 docker

Installation docker-20.10.12 CentOS 7.9：https://www.cnblogs.com/huaxiayuyi/p/16775236.html

 

五、配置环境变量

vim /etc/profile
export PATH=$PATH:/opt/cni/bin
# 配置生效
source /etc/profile

 

六、启动 Containerd

1 生成默认配置文件

[root@web01 ~]# containerd config default > /etc/containerd/config.toml

[root@ecs-65685 ~]# ll /etc/containerd/
total 8
-rw-r--r-- 1 root root 6989 Oct 13 17:32 config.toml

# --config，-c可以在启动守护程序时更改此路径
# 配置文件的默认路径位于 /etc/containerd/config.toml

2 Containerd官方操作手册

默认cri-containerd-cni包中会有containerd启动脚本，我们已经解压到对应的目录，可以直接调用启动。

# 添加开机启动
[root@ecs-65685 ~]# systemctl enable containerd --now

[root@ecs-65685 ~]# # 查看containerd启动状态

3 执行下面的命令启动 containerd 服务并查看服务的状态

sudo systemctl daemon-reload
sudo systemctl enable containerd.service
sudo systemctl start containerd.service
sudo systemctl status containerd.service

4 ctr 在解压包中已经附带了，直接可以使用

[root@ecs-65685 ~]# ctr version
Client:
  Version:  v1.6.5
  Revision: 96df0994faabc1944fc614e52b0b3c6feb609a57
  Go version: go1.17.11

Server:
  Version:  v1.6.5
  Revision: 96df0994faabc1944fc614e52b0b3c6feb609a57
  UUID: 783225fc-4c01-40b8-b15e-3acb1eed33dc

至此 containerd 已经安装成功！
