OpenStack Train版-1.安装基础环境&服务

Posted 2020-12-10 wang-hongwei

 

1. 基础环境

1.1 主机名&ip

IP地址	主机名	配置
10.0.0.11	controller	4C8G
10.0.0.31	compute01	4C8G

1.2 ntp时间同步

[root@controller ~]# yum install chrony -y
[root@controller ~]# vim /etc/chrony.conf 
allow 10.0.0.0/24
[root@controller ~]# systemctl restart chronyd.service 
[root@controller ~]# systemctl enable chronyd.service 

1.3 关闭防火墙 selinux

systemctl stop firewalld

1.4 安装train版yum源

[root@controller ~]# yum install centos-release-openstack-train -y

2.安装客户端【controller节点】

[root@controller ~]# yum install python-openstackclient -y

3.安装数据库【controller节点】

yum install mariadb mariadb-server python2-Pymysql

cat > /etc/my.cnf.d/openstack.cnf << EOF
[mysqld]
bind-address = 10.0.0.11

default-storage-engine = innodb #默认存储引擎
innodb_file_per_table = on #每张表独立表空间文件
max_connections = 4096 #最大连接数
collation-server = utf8_general_ci #默认字符集
character-set-server = utf8
EOF

systemctl enable mariadb.service
systemctl start mariadb.service

mysql_secure_installation
回车--->n--->一路y

4.安装消息队列服务【controller节点】

[root@controller ~]# yum install rabbitmq-server -y

[root@controller ~]# systemctl enable rabbitmq-server.service
[root@controller ~]# systemctl start rabbitmq-server.service

创建用户
[root@controller ~]# rabbitmqctl add_user openstack RABBIT_PASS
Creating user "openstack"

授予权限
[root@controller ~]# rabbitmqctl set_permissions openstack ".*" ".*" ".*"
Setting permissions for user "openstack" in vhost "/"

安装好之后，使用netstat -tnlup 查看，如果有下图所示的25672和5672端口，则表示安装成功。

5.安装memcache【controller节点】

yum install memcached python-memcached

sed -i ‘/OPTIONS/cOPTIONS="-l 0.0.0.0"‘ /etc/sysconfig/memcached

systemctl enable memcached.service
systemctl start memcached.service
安装和启动好之后，同样使用netstat -tnlup查看端口情况，看到11211端口有程序在侦听则表示memcache安装成功

6.安装etcd【controller节点】

yum install etcd

cp -a /etc/etcd/etcd.conf{,.bak}
cat > /etc/etcd/etcd.conf <<EOF 
#[Member]
ETCD_DATA_DIR="/var/lib/etcd/default.etcd"
ETCD_LISTEN_PEER_URLS="http://10.0.0.11:2380"
ETCD_LISTEN_CLIENT_URLS="http://10.0.0.11:2379"
ETCD_NAME="controller"
#[Clustering]
ETCD_INITIAL_ADVERTISE_PEER_URLS="http://10.0.0.11:2380"
ETCD_ADVERTISE_CLIENT_URLS="http://10.0.0.11:2379"
ETCD_INITIAL_CLUSTER="controller=http://10.0.0.11:2380"
ETCD_INITIAL_CLUSTER_TOKEN="etcd-cluster-01"
ETCD_INITIAL_CLUSTER_STATE="new"
EOF

systemctl enable etcd
systemctl start etcd
安装和启动好之后，同样使用netstat -tnlup查看端口情况，看到2379和2380端口有程序在侦听则表示etcd安装成功
