macports国内加速

正常进行sudo port selfupdate的时候，可能会遇到一直卡住的情况。

[~]$ sudo port selfupdate
Password:
--->  Updating MacPorts base sources using rsync

这一般就是服务器的问题。所以需要更换国内服务器进行加速，还好，清华源有。

打开/opt/local/etc/macports/macports.conf，修改：

# The rsync server for fetching MacPorts base during selfupdate. This
# setting is NOT used when downloading ports trees; ports trees are
# configured using the file referenced by sources_conf. See
# https://trac.macports.org/wiki/Mirrors#MacPortsSource for a list of
# available servers.
# rsync_server        	rsync.macports.org
# rsync_server        ftp.leg.uct.ac.za
rsync_server        pek.cn.rsync.macports.org

再打开/opt/local/etc/macports/sources.conf，修改：

# For proper functionality of various resources (port groups, mirror
# sites, etc.), the primary MacPorts source must always be tagged
# "[default]", even if switched from the default "rsync://" URL.

# rsync://rsync.macports.org/macports/release/tarballs/ports.tar [default]
# rsync://ftp.leg.uct.ac.za/pub/packages/macports/release/ports/ [default]
rsync://pek.cn.rsync.macports.org/macports/release/tarballs/ports.tar

这时再更新：

[~]$ sudo port -v sync
Warning: No default port source specified in /opt/local/etc/macports/sources.conf, using last source as default
--->  Updating the ports tree
Synchronizing local ports tree from rsync://pek.cn.rsync.macports.org/macports/release/tarballs/ports.tar
