公有云配置

區域： 同一個區域中的云主機是可以互相連通的，不通區域云主機是不能使用內部網路互相通信的

選擇離自己比較近的區域，可以減少網路延時卡頓

華為云yum源配置 https://support.huaweicloud.com/ecs_faq/ecs_faq_1003.html

跳板機配置

配置yum源，安裝軟體包

[root@ecs-proxy ~]# rm -rf /etc/yum.repos.d/*.repo
[root@ecs-proxy ~]# curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.myhuaweicloud.com/repo/CentOS-Base-7.repo
[root@ecs-proxy ~]# yum clean all
[root@ecs-proxy ~]# yum makecache
[root@ecs-proxy ~]# yum install -y net-tools lftp rsync psmisc vim-enhanced tree vsftpd  bash-completion createrepo lrzsz iproute
[root@ecs-proxy ~]# mkdir /var/ftp/localrepo
[root@ecs-proxy ~]# cd /var/ftp/localrepo
[root@ecs-proxy ~]# createrepo  .
[root@ecs-proxy ~]# createrepo --update . # 更新
[root@ecs-proxy ~]# systemctl enable --now vsftpd

優化系統服務

[root@ecs-proxy ~]# systemctl stop postfix
[root@ecs-proxy ~]# yum remove -y postfix firewalld-*
[root@ecs-proxy ~]# yum install chrony
[root@ecs-proxy ~]# vim /etc/chrony.conf 
# 注釋掉 server 開頭行，添加下面的配置
server ntp.myhuaweicloud.com minpoll 4 maxpoll 10 iburst
[root@ecs-proxy ~]# systemctl enable --now chronyd
[root@ecs-proxy ~]# chronyc sources -v
# 驗證配置結果 ^* 代表成功
[root@ecs-proxy ~]# vim /etc/cloud/cloud.cfg
# manage_etc_hosts: localhost 注釋掉這一行
[root@ecs-proxy ~]# reboot

安裝配置ansible管理主機

[root@ecs-proxy ~]# cp -a ansible_centos7 /var/ftp/localrepo/ansible
[root@ecs-proxy ~]# cd /var/ftp/localrepo
[root@ecs-proxy ~]# createrepo --update .
[root@ecs-proxy ~]# vim /etc/yum.repos.d/local.repo 
[local_repo]
name=CentOS-$releasever – Localrepo
baseurl=ftp://192.168.1.252/localrepo
enabled=1
gpgcheck=0
[root@ecs-proxy ~]# yum makecache
[root@ecs-proxy ~]# yum install -y ansible
# 去華為云網頁下載秘鑰，并上傳秘鑰到跳板機
[root@ecs-proxy ~]# mv luck.pem /root/.ssh/id_rsa
[root@ecs-proxy ~]# chmod 0400 /root/.ssh/id_rsa

模板鏡像配置

購買云主機使用秘鑰認證

配置yum源，安裝軟體包

[root@ecs-host ~]# passwd root
[root@ecs-host ~]# rm -rf /etc/yum.repos.d/*.repo
[root@ecs-host ~]# curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.myhuaweicloud.com/repo/CentOS-Base-7.repo
[root@ecs-host ~]# vim /etc/yum.repos.d/local.repo 
[local_repo]
name=CentOS-$releasever – Localrepo
baseurl=ftp://192.168.1.252/localrepo
enabled=1
gpgcheck=0
[root@ecs-host ~]# yum clean all
[root@ecs-host ~]# yum makecache
[root@ecs-host ~]# yum repolist
[root@ecs-host ~]# yum install -y net-tools lftp rsync psmisc vim-enhanced tree lrzsz bash-completion lrzsz iproute

優化系統服務

[root@ecs-host ~]# systemctl stop postfix atd tuned
[root@ecs-host ~]# yum remove -y postfix at audit tuned kexec-tools firewalld-*
[root@ecs-host ~]# yum install chrony
[root@ecs-host ~]# vim /etc/chrony.conf 
# 注釋掉 server 開頭行，添加下面的配置
server ntp.myhuaweicloud.com minpoll 4 maxpoll 10 iburst
[root@ecs-host ~]# systemctl enable --now chronyd
[root@ecs-host ~]# chronyc sources -v
# 驗證配置結果 ^* 代表成功
[root@ecs-host ~]# vim /etc/cloud/cloud.cfg
# manage_etc_hosts: localhost 注釋掉這一行
[root@ecs-host ~]# yum clean all 
[root@ecs-host ~]# poweroff

關機以后把主機系統盤制作為模板
