云平臺部署管理架構(gòu)

公有云配置

區(qū)域： 同一個區(qū)域中的云主機是可以互相連通的，不通區(qū)域云主機是不能使用內(nèi)部網(wǎng)絡(luò)互相通信的

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，安裝軟件包

[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 .                       # 更新命令
[root@ecs-proxy ~]# systemctl enable --now vsftpd

優(yōu)化系統(tǒng)服務(wù)

[root@ecs-proxy ~]# systemctl stop postfix atd tuned
[root@ecs-proxy ~]# yum remove -y postfix at audit tuned kexec-tools firewalld-*
[root@ecs-proxy ~]# vim /etc/cloud/cloud.cfg
# manage_etc_hosts: localhost 注釋掉這一行
[root@ecs-proxy ~]# reboot

補充：
優(yōu)化原則：卸載掉所有非必要的服務(wù)
/etc/cloud/cloud.cfg 是華為云服務(wù)器內(nèi)置文件，manage_etc_hosts: localhost 代表開機自啟動一些服務(wù)配置

安裝配置ansible管理主機

[root@ecs-proxy ~]# tar zxf ansible_centos7.tar.gz
[root@ecs-proxy ~]# yum install -y ansible_centos7/*.rpm
[root@ecs-proxy ~]# ssh-keygen -t rsa -b 2048 -N '' -f /root/.ssh/id_rsa
[root@ecs-proxy ~]# chmod 0400 /root/.ssh/id_rsa
[root@ecs-proxy ~]# ssh-copy-id -i /root/.ssh/id_rsa 模板主機IP

- 模板鏡像配置

配置yum源，安裝軟件包

[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 iproute

優(yōu)化系統(tǒng)服務(wù)

[root@ecs-host ~]# systemctl stop postfix atd tuned
[root@ecs-host ~]# yum remove -y postfix at audit tuned kexec-tools firewalld-*
[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
