使用koa-body遇到的坑

Posted 2023-04-08

参考技术A koa-body可以实现文件上传，同时也可以让koa能获取post请求的参数,在使用的过程中，遇到了一下的坑

查了很久没有搞明白是什么原因，后来把koa-bodyParser注释掉就行了，估计是koa-body跟koa-bodyParser冲突了，它们都可以获取post请求参数，所有用了koa-body就不需要用koa-bodyParser了。

原因是我封装了一个中间件，

用来同时获取get和post请求参数，顺序（中间件是有顺序的）放错了，放在koa-body后面就行了。

packstack 部署遇到的坑

centos7 部署icehouse 遇到了好多坑

第一次安装使用 使用 packstack --allinone  失败

重复安装的时候使用第一次生成的 answer-file

packstack --answer-file=/root/packstack-answers-20161115-033728.txt

SequenceError: Error appeared during Puppet run: 10.0.4.15_mariadb.pp
Error: mysqladmin -u root password ‘5c2dcec12fcb4538‘ returned 1 instead of one of [0]^[[0m
You will find full trace in log /var/tmp/packstack/20161115-031426-zz2wLu/manifests/10.0.4.15_mariadb.pp.log

在 10.0.4.15_mariadb.pp.log 中发现  

ESC[mNotice: /Stage[main]/Mysql::Config/Exec[set_mysql_rootpw]/returns: ^Gmysqladmin: connect to server at ‘localhost‘ failedESC[0m
ESC[mNotice: /Stage[main]/Mysql::Config/Exec[set_mysql_rootpw]/returns: error: ‘Access denied for user ‘root‘@‘localhost‘ (using password: NO)‘ESC[0m

 

解决办法：

给mariadb的root设置密码，并修改answer-file 中的 CONFIG_MARIADB_PW 为mariadb 的root密码

# Password for the MariaDB admin user

CONFIG_MARIADB_PW=123

ERROR : Error appeared during Puppet run: 10.0.4.15_osclient.pp

解决办法：将 /usr/lib/python2.7/site-packages/packstack/puppet/templates/openstack_client.pp 中的 python-iso8601 替换成 python2-iso8601

sed -i ‘s/python-iso8601/python2-iso8601/‘ /usr/lib/python2.7/site-packages/packstack/puppet/templates/openstack_client.pp

_mongodb.pp: [ ERROR ]
Applying Puppet manifests [ ERROR ]

ERROR : Error appeared during Puppet run: 10.0.4.15_mongodb.pp
Error: Could not start Service[mongodb]: Execution of ‘/usr/bin/systemctl start mongod‘ returned 1: Job for mongod.service failed because the control process exited with error code. See "systemctl status mongod.service" and "journalctl -xe" for details.
You will find full trace in log /var/tmp/packstack/20161115-054317-dIhK2C/manifests/10.0.4.15_mongodb.pp.log

原因是mongodb 没启动起来

查看mongodb的日志，会看到这么一行    Insufficient free space for journal files  ,原因是因为mongo的journa目录下空间小于3379MB ，

解决办法：

修改配置文件  /etc/mongod.conf 

vi /etc/mongod.conf 

# Use a smaller default file size (false by default)
smallfiles = true   # 修改这里就可以了
