1. 两台虚拟机，安装Centos7系统 两个网卡 -- 一个NAT模式，一个仅主机模式 两个硬盘 -- 一个20GB，一个50GB 内存 -- 主 2.6GB（根据自己的配置，大于2G即可） 从 1.6 GB 2. 配置网络 （参照博文 ”Centos7 配置网络） 3. 关闭 selinux ,关闭iptables(两台机器都要操作） //在Centos7 ，firewalld就是iptables [[email protected] ~]# setenforce 0 [[email protected] ~]# vi /etc/selinux/config [[email protected] ~]# systemctl stop firewalld [[email protected] ~]# systemctl disable firewalld rm ‘/etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service‘ rm ‘/etc/systemd/system/basic.target.wants/firewalld.service‘ 4. 关闭NetworkManager(两台机器都要操作） [[email protected] ~]# systemctl stop NetworkManager [[email protected] ~]# systemctl disable NetworkManager rm ‘/etc/systemd/system/multi-user.target.wants/NetworkManager.service‘ rm ‘/etc/systemd/system/dbus-org.freedesktop.NetworkManager.service‘ rm ‘/etc/systemd/system/dbus-org.freedesktop.nm-dispatcher.service‘
/* 定义密码 */ /* 在部署openstack过程 ，会有很多地方使用到密码 。 为了方便管理和安全，可以先定义好密码 ，利用mkpasswd生成随机字符串 */ （两台机器都安装） [[email protected] ~]# yum install -y expect [[email protected] ~]# mkpasswd -s 0 //生成随机字符串 /* 范本 */ Database password (no variable used) Root password for the database tn1Pi6Ytm ADMIN_PASS Password of user admin 3qiVpzU2x CEILOMETER_DBPASS Database password for the Telemetry service Czn3bF1hm CEILOMETER_PASS Password of Telemetry service user ceilometer abquh12GU CINDER_DBPASS Database password for the Block Storage service O3bwbpoZ3 CINDER_PASS Password of Block Storage service user cinder hf8LX9bow DASH_DBPASS Database password for the dashboard 5qBZxnn1g DEMO_PASS Password of user demo 9TtbgaA1q GLANCE_DBPASS Database password for Image service Zznky4tP0 GLANCE_PASS Password of Image service user glance Wuyaf4cV6 HEAT_DBPASS Database password for the Orchestration service b7Fk5wjLg HEAT_DOMAIN_PASS Password of Orchestration domain 7Gotb3eoH HEAT_PASS Password of Orchestration service user heat eqQ2jLgz0 KEYSTONE_DBPASS Database password of Identity service f6zx0gURv NEUTRON_DBPASS Database password for the Networking service quidyOC50 NEUTRON_PASS Password of Networking service user neutron mdcGVl29i NOVA_DBPASS Database password for Compute service RYgv0rg7p NOVA_PASS Password of Compute service user nova hsSNsqc43 RABBIT_PASS Password of user guest of RabbitMQ o3NXovnz5 SWIFT_PASS Password of Object Storage service user swift 6ci5xWOdk METADATA_SECRET m8uhmQTu2
/* 设置主机名 */ 1.两台机器，设置hostname //方法 --〉1. hostname + 主机名 --〉2. vi /etc/hostname 让其永久生效 2. 编辑/etc/hosts 192.168.216.120 master 192.168.216.126 slave /* 配置完后， 可以ping 一下hostname 看是否通 */
/* 同步时间 */ //master [[email protected] ~]# yum install -y chrony [[email protected] ~]# vi /etc/chrony.conf //add or change allow 192.168.216.0/24 //ip网段 [[email protected] ~]# systemctl enable chronyd.service [[email protected] ~]# systemctl start chronyd.service [[email protected] ~]# ps aux|grep chronyd chrony 10140 0.2 0.0 98552 1300 ? S 15:07 0:00 /usr/sbin/chron yd root 10148 0.0 0.0 112656 996 pts/0 S+ 15:07 0:00 grep --color=au to chronyd //slave [[email protected] ~]# yum install -y chrony [[email protected] ~]# vi /etc/chrony.conf //add or change,其他的解释掉 server master iburst //master为主名 [[email protected] ~]# systemctl enable chronyd.service [[email protected] ~]# systemctl start chronyd.service [[email protected] ~]# ps aux|grep chronyd chrony 10639 0.1 0.0 98552 1296 ?
