使用devstack 一键安装 openstack详细过程和遇到的坑

安装参考链接 https://www.cnblogs.com/dyd168/p/14482507.html

后面都是解决坑。。。。

安装之前以下操作是必要的：

[root@jay-server ~]# vim /etc/selinux/config
[root@jay-server ~]# setenforce 0
[root@jay-server ~]# cat /etc/selinux/config 

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of these three values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected. 
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

注意点：遇到安装错误，重装需执行 ./clean.sh ==》 /unstack.sh ==》 ./stack.sh

安装过程中很多东西需要从github下载，所以最好提前准备好代理服务，执行安装之前代理一下

export https_proxy=代理服务:端口

坑一：

ERROR /opt/stack/devstack/lib/neutron_plugins/ovn_agent:174 Socket

As said above by Sage Ren, When we are going to run Command $ ./stack.sh first time and the above error is encounters.

This error is solved easily by following below steps.

  1. Go to neutron_plugin folder, by default the folder is reside in the /opt/stack/devstack/lib/neutron_plugins directory.
  2. open ovn_agent file with sudo privileges.
  3. change line 116 which looks like this OVS_RUNDIR=$OVS_PREFIX/var/run/openvswitch you just have to change ovn by replacing of openvswitch. after change your line will become OVS_RUNDIR=$OVS_PREFIX/var/run/ovn now save the file.
  4. Now go to /var/run/ovn/ directory, In this you will find ovn folder over there. Just remove the folder using $sudo rm -rf ovn command
  5. Now first run ./clean.sh and then ./unstack.sh command
  6. reboot the system
  7. run ./stack.sh

 

坑二：（这个我没遇到，来自网上）

==========================
[Call Trace]
./stack.sh:499:check_path_perm_sanity
/opt/stack/devstack/functions:612:die
[ERROR] /opt/stack/devstack/functions:612 Invalid path permissions
==========================
fixed:
$ sudo chmod 755 /opt/stack
==========================

 

坑三：python3.6 安装不了 futures-3.0.5

ERROR: Cannot install nova because these package versions have conflicting dependencies.

The conflict is caused by:
    pypowervm 1.1.26 depends on futures>=3.0; python_version == "3.6"
    The user requested (constraint) futures===3.0.5

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

ERROR: ResolutionImpossible: for help visit https://pip.pypa.io/en/latest/user_guide/#fixing-conflicting-dependencies

fixed:

$ sudo python3 setup.py install

坑四：（这个我没遇到，来自网上）

logout and login

坑五：这个其实是因为上次执行报错，没有执行clean.sh

坑六：按教程安装完之后，重启电脑服务没起来

开放80 6640 6080 9696端口

 开启启动以下服务：

systemctl ebable httpd
systemctl enable memcached
 
 
cat admin-openrc.sh
export OS_USERNAME=admin
export OS_PASSWORD=duanyd
export OS_PROJECT_NAME=admin
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_DOMAIN_NAME=Default
export OS_AUTH_URL=http://192.168.0.17/identity
export OS_IDENTITY_API_VERSION=3

 

cat start_service.sh
systemctl start devstack@n-super-cond.service
systemctl start devstack@n-sch.service
systemctl start devstack@n-cond-cell1.service

 

查看日志的方法：

systemctl status "devstack@*"
systemctl list-unit-files | grep devstack
journalctl -u devstack@q-svc -f
