0x01.网络配置
#准备服务器 192.168.88.133 controller 192.168.88.134 network 192.168.88.135 compute1 #配置所有节点的hosts cat >/etc/hosts <<EOF 192.168.88.133 controller 192.168.88.134 network 192.168.88.135 compute1 EOF #测试所有hosts添加是否生效 ping -c 4 controller;ping -c 4 network;ping -c 4 compute1 #关闭防火墙和selinux systemctl stop firewalld;setenforce 0
0x02.NTP网络时间服务器
a)主节点配置[root@controller ~]# yum install -y ntp [root@controller ~]# vi /etc/ntp.conf #server NTP_SERVER iburst restrict 192.168.88.0 mask 255.255.255.0 nomodify notrap restrict -4 default kod notrap nomodify restrict -6 default kod notrap nomodify [root@controller ~]# systemctl enable ntpd.service [root@controller ~]# systemctl start ntpd.service
b)其他节点[root@network ~]# yum install -y ntp [root@network ~]# echo "server controller iburst" >/etc/ntp.conf [root@network ~]# systemctl enable ntpd.service [root@network ~]# systemctl start ntpd [root@compute1 ~]# yum install -y ntp [root@compute1 ~]# echo "server controller iburst" >/etc/ntp.conf [root@compute1 ~]# systemctl enable ntpd.service [root@compute1 ~]# systemctl start ntpd
c)确认以上操作是否成功(所有节点)ntpq -c peers; ntpq -c assoc
0x03.OpenStack packages(所有节点)
yum install -y yum-plugin-priorities yum install -y http://mirrors.opencas.cn/epel/7/x86_64/e/epel-release-7-5.noarch.rpm yum install -y http://rdo.fedorapeople.org/openstack-juno/rdo-release-juno.rpm yum install -y openstack-selinux
0x04.数据库(控制节点)
[root@controller ~]# yum install -y mariadb mariadb-server MySQL-python [root@controller ~]# vi /etc/my.cnf [mysqld] bind-address = 192.168.88.133 default-storage-engine = innodb innodb_file_per_table collation-server = utf8_general_ci init-connect = 'SET NAMES utf8' character-set-server = utf8 [root@controller ~]# systemctl enable mariadb.service [root@controller ~]# systemctl start mariadb.service [root@controller ~]# mysql_secure_installation /usr/bin/mysql_secure_installation: line 379: find_mysql_client: command not found NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY! In order to log into MariaDB to secure it, we'll need the current password for the root user. If you've just installed MariaDB, and you haven't set the root password yet, the password will be blank, so you should just press enter here. Enter current password for root (enter for none): OK, successfully used password, moving on... Setting the root password ensures that nobody can log into the MariaDB root user without the proper authorisation. Set root password? [Y/n] y New password: Re-enter new password: Password updated successfully! Reloading privilege tables.. ... Success! By default, a MariaDB installation has an anonymous user, allowing anyone to log into MariaDB without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment. Remove anonymous users? [Y/n] y ... Success! Normally, root should only be allowed to connect from 'localhost'. This ensures that someone cannot guess at the root password from the network. Disallow root login remotely? [Y/n] y ... Success! By default, MariaDB comes with a database named 'test' that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment. Remove test database and access to it? [Y/n] n ... skipping. Reloading the privilege tables will ensure that all changes made so far will take effect immediately. Reload privilege tables now? [Y/n] y ... Success! Cleaning up... All done! If you've completed all of the above steps, your MariaDB installation should now be secure. Thanks for using MariaDB!
