一、安装过程

1、查看docker版本（已安装docker）

命令

docker version

打印返回

  GitCommit:        de40ad0

2、安装centos默认最新版（latest）

2.1 拉取镜像

docker pull centos

2.2 查看镜像

命令

docker images

打印返回

REPOSITORY                           TAG       IMAGE ID       CREATED        SIZE
centos                               latest    5d0da3dc9764   2 years ago    231MB

3、启动centos镜像

docker run --name centos-1 -p 10080:80 -v /home/cc/centos:/mnt/software -itd --privileged centos bash

上述命令含义： --name docker启动一个自定义命名为：centos-1 -p 为绑定端口80映射到宿主机10080端口 -v 为挂载到宿主机/home/cc/centos文件目录下共享文件 -i 打开STDIN，用于控制台交互 -t 分配tty设备，该可以支持终端登录，默认为false -d 让容器在后台运行（如需进入容器命令行可以不加） --privileged 能够让容器中的进程获取到主机的完整权限，包括root权限 bash 在命令中运行

4、进入容器

docker exec -it centos-1 bash

5、安装依赖工具

# 安装make编译命令      

yum -y install cmake

# 安装ifconfig命令      

yum -y install net-tools

# 安装wget命令      

yum -y install wget

6、安装依赖库

yum -y install openssl-devel gcc gcc-c++ wget make

7、下载并安装keepalived

#下载安装包
wget http://www.keepalived.org/software/keepalived-2.2.7.tar.gz
 
# 解压缩
tar xvf keepalived-2.2.7.tar.gz
 
cd keepalived-2.2.7
 
# 设置编译位置
./configure --prefix=/usr/local/keepalived  --sysconf=/etc
 
# 编译安装
make && make install
 
# 将keepalived主程序加入到环境变量 
cp /usr/local/keepalived/sbin/keepalived /usr/sbin/keepalived
 
# keepalived启动脚本（源码目录下），放到/etc/init.d/目录下就可以使用service命令便捷调用
cp /usr/local/keepalived-2.2.7/keepalived/etc/init.d/keepalived  /etc/init.d/keepalived

8、配置keepalived.conf

vi /etc/keepalived/keepalived.conf

内容如下

! Configuration File for keepalived

global_defs {
   #路由id：当前安装keepalived节点主机的标识符，全局唯一
   router_id keep_130
}

vrrp_instance VI_1 {
    # 表示的状态，当前的130服务器为nginx的主节点，MASTER/BACKUP
    state MASTER
    # 当前实例绑定的网卡（根据自己实际网卡配置）
    interface eth0
    # 保证主备节点一致
    virtual_router_id 51
    # 优先级/权重，谁的优先级高，在MASTER挂掉以后，就能成为MASTER
    priority 100
    # 主备之间同步检查的时间间隔，默认1s
    advert_int 1
    # 认证授权的密码，防止非法节点的进入
    authentication {
        auth_type PASS
        auth_pass 1111
    }
    # 虚ip地址（vip），实现ip漂移的地址（根据自己需求配置）
    virtual_ipaddress {
        192.168.10.100
    }
}

9、启动keepalived服务

service keepalived start

或

systemctl start keepalived.service

或

keepalived -l -f /etc/keepalived/keepalived.conf

10、查看keepalived服务

10.1 查看运行状态

systemctl管理查看

systemctl status keepalived.service

或直接查看进程

ps -ef|grep keepalived

打印返回如下：

root        1319       1  0 Nov28 ?        00:00:00 keepalived -l -f /etc/keepalived/keepalived.conf
root        1320    1319  0 Nov28 ?        00:00:18 keepalived -l -f /etc/keepalived/keepalived.conf
root        1806       1  0 05:50 pts/0    00:00:00 grep --color=auto keepalived

10.2 查看ip挂载情况

命令

ip addr

打印返回，可以看到192.168.10.100的IP已经成功挂载

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
10: eth0@if11: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default 
    link/ether 02:42:ac:11:00:03 brd ff:ff:ff:ff:ff:ff link-netnsid 0
    inet 172.17.0.3/16 brd 172.17.255.255 scope global eth0
       valid_lft forever preferred_lft forever
    inet 192.168.10.100/32 scope global eth0
       valid_lft forever preferred_lft forever

11、关闭keepalived服务

service keepalived stop

或杀死keepalived相关进程

pkill keepalived

二、一些问题

1、无法下载？

问题提示

CentOS Linux 8 - AppStream 75 B/s \| 38 B 00:00 Error: Failed to download metadata for repo 'appstream': Cannot prepare internal mirrorlist: No URLs in mirrorlist

解决方法

首先，进入到 yum 的 repos 目录

cd /etc/yum.repos.d/

• 🔔其次，修改 centos 文件内容

sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-*
sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g' /etc/yum.repos.d/CentOS-*

• 🔔 然后，生成缓存更新（第一次更新，速度稍微有点慢，耐心等待两分钟左右）

yum makecache

• 🔔 最后，运行 yum update （过程较慢，看到 Complete! 就成功了）

yum update -y

• 🔔 重新执行安装 cmake、net-tools、openssl-devel gcc gcc-c++ wget make等

yum -y install cmake

2、编译时报错，需要安装libnl

问题提示

*** WARNING - this build will not support IPVS with IPv6. Please install libnl/libnl-3 dev libraries to support IPv6 with IPVS.

解决方法

网上给出的解决办法是

yum -y install libnl libnl-devel

若此时依旧无法安装，可参考下面手动下载

wget http://mirror.centos.org/centos/7/os/x86\_64/Packages/libnl-1.1.4-3.el7.x86\_64.rpm
wget http://mirror.centos.org/centos/7/os/x86\_64/Packages/libnl-devel-1.1.4-3.el7.x86\_64.rpm
rpm -ivh libnl-1.1.4-3.el7.x86_64.rpm
rpm -ivh libnl-devel-1.1.4-3.el7.x86_64.rpm
