手动升级wordpress的方法 进入到wordpress的后台管理发现有新版本更新时,使用系统自带的自动更新,总是出现300秒超时导致升级失败。 Downloading update from http://wordpress.org/wordpress-3.1.1.zip… Download failed.: Operation timed out after 300 seconds with 1340586 bytes received Installation Failed 使用terminal登陆到系统使用wget测试下载速度,发现服务器下载wordpress包的速度其慢无比,每秒只有3KB左右的速度。

之后再使用wordpress的自动升级,就可以成功了^_^。 Downloading update from http://wordpress.org/wordpress-3.1.1.zip… Unpacking the update… Verifying the unpacked files… Installing the latest version… Upgrading database… WordPress updated successfully Go to Dashboard 升级成功后再把/etc/hosts再修改回来。
