ODPF3.0自动化部署手册中3.3.5rabbitmquser（任一节点）
第二行修改：rabbitmqctl set_permissions openstack ".*" ".*" ".*"
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
控制节点Neutron授权访问
neutron port-list |grep 10.20.1.81
neutron port-update b5c75055-d03d-45d1-b6c9-360d0bd65807 --allowed-address-pair ip_address=10.20.1.220 --allowed-address-pair ip_address=10.20.1.210 --allowed-address-pair ip_address=10.20.1.200
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
网络和计算节点系统扩容
fdisk /dev/vda
partprobe
pvcreate /dev/vda3
vgextend centos /dev/vda3
lvextend -L +42G /dev/mapper/centos-root
xfs_growfs /dev/mapper/centos-root
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
内核升级
tar -xf linux-3.18.4.tar.xz -C /usr/src/
cd /usr/src/linux-3.18.4/
make menuconfig
make oldconfig
make -j 6
make modules_install install
uname -r
awk -F\' '$1=="menuentry " {print $2}' /etc/grub2.cfg

-------------------------------------------------------------------------------------------------------------------
-------------------------------------------------------------------------------------------------------------------
-------------------------------------------------------------------------------------------------------------------
-------------------------------------------------------------------------------------------------------------------
创建云硬盘失败
cinder-volumes未分配空间
解决办法
fdisk /dev/vda
partprobe
pvcreate /dev/vda3
vgcreate cinder-volumes /dev/vda3
vg_cinder
systemctl enable openstack-cinder-volume.service target.service
systemctl restart openstack-cinder-volume.service target.service
cinder service-list
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
运行autoDeploy.sh HA
/etc/yum.repos.d/
nnit-openstack.repo
运行autoDeploy.sh openstack
CentOS-Base.repo CentOS-CR.repo CentOS-Debuginfo.repo CentOS-fasttrack.repo CentOS-Media.repo CentOS-Sources.repo CentOS-Vault.repo epel.repo epel-testing.repo nnit-openstack.repo
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
创建云主机失败
Unable to establish connection to http://127.0.0.1:9696/v2.0/extensions.json
源于计算节点安装失败，在进行网络节点和计算节点内核升级时候会自动在/etc/yum.repos.d/
生成不必要的yum源包，需要手动删除。
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
修改hostname
vi /etc/sysconfig/network
添加
HOSTNAME=
NETWORKING=yes
然后运行
hostnamectl set-hostname
reboot
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Dashboard根目录
/usr/share/openstack-dashboard/openstack_dashboard
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
卷出现不可用或者持续回滚
cinder show +ID
cinder reset-state +ID --state available/in-use
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
检查mariadb
netstat -ntpl | grep sql
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
用户资源限制
cinder absolute-limits
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
控制直接执行openstack
没有删除、etc/yum.repos.d/多余yum源
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
简单快速复制
scp -r [email protected]:/home/centos-kernel-3.18.4-package /home/
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
局域网yum源制作
tar -xzvf rpm.tar -C /var/www/html
使用 自己准备的 RPM 包 （这里以 nnit-openstack为例）
（1）、在目录 /var/www/html/ 下建立一个文件夹，把准备的 RPM包放到里面
（2）、创建仓库信息文件，在目录 /var/www/html/ 下执行：createrepo nnit-openstack
查看nnit-openstack目录，可以看到 repodate 文件已经生成
nnit-openstack yum源搭建OK
--------------------------------------------------------------------------------------
--------------------------------------------------------------------------------------
ps -ef |grep rabbitmq
完事了之后 把安装文件全部删除干净
脚本 安装包什么的
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
ps aux | grep mysqld
kill -s 9 +id
--------------------------------------------------------------------
------------------------------------------------------------------------------------------------------------------------------------------------
服务器高并发：
yum -y install httpd-tools
ab -n 200000 -c 3000 http://10.20.1.67/accounts/login/
