标签: ubuntu mariadb maxscale

我正在使用mariadb运行Ubuntu 16.04,

我已经在官方网站上安装了maxscale,

  

https://downloads.mariadb.com/MaxScale/2.0.4/ubuntu/dists/xenial/main/binary-amd64/maxscale-2.0.4-1.ubuntu.xenial.x86_64.deb

现在我无法启动该服务,而不是那么有用

/etc/maxscale.cnf

[maxscale]
threads=1

[server1]
type=server
address=127.0.0.1
port=3306
protocol=MySQLBackend

有什么想法吗?

无法启动的原因是您没有定义服务。虽然在错误消息中对此进行了解释,但解释起来并不容易:2017-02-28 11:41:11 error : Failed to start all MaxScale services. Exiting.

尝试在配置中添加以下三个对象:

[Read-Connection-Router]
type=service
router=readconnroute
servers=server1
user=maxuser
passwd=maxpwd

[Read-Connection-Listener]
type=listener
service=Read-Connection-Router
protocol=MySQLClient
port=4008

[MySQL-Monitor]
type=monitor
module=mysqlmon
servers=server1
user=maxuser
passwd=maxpwd
monitor_interval=1000

Read-Connection-Router是MaxScale提供的服务。 Read-Connection-Listener是客户端可以连接的网络端口,它链接到先前定义的服务。最后一个对象MySQL-Monitor是数据库监视器,它主动监视数据库服务器的状态。

配置中定义的mysqlmon模块用于标准主从复制集群。如果您正在使用Galera群集,则需要使用galeramon模块。
