扶墙向:本篇讲述的是如何选择VPS,以及对购买完后的VPS进行测试及系统升级……
#VPS的选择
如何选择VPS,第一要素自然是是看延迟咯,所以我们先上 这个 网站测试下你到一些常见的VPS供应商机房的延迟,下面给张图:

测完延迟后就选一款适合你的…..

#VPS的测试
这里我们使用秋水逸冰大佬的一键测试脚本来进行VPS性能的测试
命令:
1
| wget -qO- bench.sh | bash
|
或者
1
| curl -Lso- bench.sh | bash
|
备注
bench.sh 既是脚本名,同时又是域名。
给个图:
测试完了,感觉还可以就留着,不行的的话就该退款退款,该换就换,千万别凑活着用,给自己找不自在,最后还发工单撕…..
#系统大版本升级
有时候,VPS商家给的系统模板并不是最新的,这时候我们就需要手动升级下系统(本文Ubuntu向)
首先,我们需要升级下软件包
1
2
| sudo apt-get update
sudo apt-get upgrade
|
接着安装update-manager-core
1
| sudo apt-get install update-manager-core
|
然后打开文件/etc/update-manager/release-upgrades,确认Prompt的值设定为lts:

| # Default behavior for the release upgrader.
[DEFAULT]
# Default prompting behavior, valid options:
#
# never - Never check for a new release.
# normal - Check to see if a new release is available. If more than one new
# release is found, the release upgrader will attempt to upgrade to
# the release that immediately succeeds the currently-running
# release.
# lts - Check to see if a new LTS release is available. The upgrader
# will attempt to upgrade to the first LTS release available after
# the currently-running one. Note that this option should not be
# used if the currently-running release is not itself an LTS
# release, since in that case the upgrader won't be able to
# determine if a newer release is available.
Prompt=lts
|
确认完毕后,我们需要处理一下可能阻碍升级的依赖关系,所以运行
1
| sudo apt-get dist-upgrade
|
最后,一切准备就绪,使用Ubuntu的发行工具执行升级
1
| sudo do-release-upgrade
|
或
1
| sudo do-release-upgrade -d
|
至此,静待系统升级完毕,期间需要重启系统,重启完毕后,使用
可以看到你的系统升级后的版本
