openstack（二）keystone

部署认证服务

分别安装mariadb/mongodb/rabbitmq/keystone/httpd/memcached

yum install -y --downloaddir=./  --downloadonly

yum install -y python-openstackclient openstack-selinux mariadb mariadb-server python2-PyMySQL mongodb-server mongodb erlang rabbitmq-server openstack-keystone httpd mod_wsgi memcached python-memcached

配置数据库/etc/my.cnf.d/openstack.cnf

cat > /etc/my.cnf.d/openstack.cnf << EOF
[mysqld]
bind-address = 192.168.3.220 #mysql地址，可分离
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

更改系统限制的最大连接数

sed -i 's#\[Manager]#\[Manager]\nDefaultLimitNOFILE=100000\nDefaultLimitNPROC=100000#g'  /etc/systemd/system.conf

sed -i 's#^\[Service]#\[Service]\nLimitNOFILE=50000\nLimitNPROC=50000#g'  /usr/lib/systemd/system/mariadb.service

配置memcached地址

sed -i 's#OPTIONS="-l 127.0.0.1,::1"#OPTIONS="-l 192.168.3.220"#g' /etc/sysconfig/memcached

配置开机启动 mariadb memcached

systemctl daemon-reload && systemctl restart mariadb memcached rabbitmq-server && systemctl enable mariadb memcached rabbitmq-server

创建reabbit用户并授权

rabbitmqctl add_user openstack openstack && rabbitmqctl set_permissions openstack ".*" ".*" ".*"

初始化数据库，并创建用户和表

flush privileges;\

select user,host from mysql.user;"

如果脚本初始化加入的选项

mysql -e "grant all on *.* to 'root'@'localhost' identified by '$PASSWD';grant all on *.* to 'root'@'%' identified by '$PASSWD';flush privileges;"  

查看数据库最大连接数

mysql -p123qwe  -e "show variables like 'max_connections';show global status like 'Max_used_connections';"

=================================================================

配置/etc/keystone/keystone.conf，添加或修改部分，其中py格式：mysql+pymysql://用户名:密码@主机地址/库

cat > /etc/keystone/keystone.conf <<EOF 
[database]
connection = mysql+pymysql://keystone:keystone@192.168.3.220/keystone
[memcache]
servers = 192.168.3.220:11211
[token]
provider = fernet
driver = memcache
EOF

=================================================================

初始化keystone库

su -s /bin/sh -c "keystone-manage db_sync" keystone

查表

mysql -ukeystone -pkeystone -e " use keystone;show tables;"

初始化keystone的admin用户并增加接入端点

keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone


keystone-manage credential_setup --keystone-user keystone --keystone-group keystone


keystone-manage bootstrap   --bootstrap-password admin       --bootstrap-admin-url http://192.168.3.220:35357/v3/ \
    --bootstrap-internal-url http://192.168.3.220:35357/v3/  --bootstrap-public-url http://192.168.3.220:5000/v3/ \
    --bootstrap-region-id RegionOne && mysql -ukeystone -pkeystone -e "select * from keystone.user;"

修改http配置并启动
