dcos下rexray服务的配置

在dcos环境下,rexray服务的默认配置文件为/opt/mesosphere/etc/rexray.conf,而其服务文件则是

/etc/systemd/system/dcos-rexray.service。

# vim /etc/systemd/system/dcos-rexray.service
[Unit]
Description=REX-Ray: A vendor agnostic storage orchestration engine

[Service]
StartLimitInterval=0
Restart=always
RestartSec=15
LimitNOFILE=16384
EnvironmentFile=/opt/mesosphere/environment
EnvironmentFile=/opt/mesosphere/etc/proxy.env
Environment=REXRAY_HOME=/
# REX-Ray fails to clean up stale lock files by itself.
ExecStartPre=/bin/rm -f /var/run/libstorage/lsx.lock
# Allow REX-Ray configuration to be changed during upgrade.
ExecStartPre=/bin/cp /opt/mesosphere/etc/rexray.conf /etc/rexray/config.yml
ExecStart=/opt/mesosphere/packages/rexray--da7f17f8a4b772c0bac3f8d289a08abd4ff272b4/bin/rexray start -f

根据该服务文件可看出,其基本功能就是拷贝/opt/mesosphere/etc/rexray.conf到rexray的配置文件/etc/rexray/config.yml中,然后启动rexray服务。

启动rexray服务:

# systemctl start dcos-rexray
