OSX 创建 randisk(或称 tmpfs)
创建步骤:
#!/bin/bash ramdisk_size_in_mb=24000 mount_point=/private/tmp ramdisk_size_in_sectors=$((${ramdisk_size_in_mb}*1024*1024/512)) ramdisk_dev_file=`hdid -nomount ram://${ramdisk_size_in_sectors}` newfs_hfs -v 'Ramdisk' ${ramdisk_dev_file} mkdir -p ${mount_point} mount -o rw,noatime,nobrowse -t hfs ${ramdisk_dev_file} ${mount_point} chown root:wheel ${mount_point} chmod 1777 ${mount_point}
开机自启:
sh-3.2# cat /Library/LaunchDaemons/com.none.randisk.plist <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Label</key> <string>com.emitial.ramdisk</string> <key>ProgramArguments</key> <array> <string>/var/root/ramdisk.sh</string> </array> <key>RunAtLoad</key> <true/> </dict> </plist>
HADEX_ FROM HELL.
