Warning: copy(/var/www/blog/wordpress/wp-admin/includes/update-core.php): failed to open stream: Permission denied in /var/www/blog/wordpress/wp-admin/includes/class-wp-filesystem-direct.php on line 309
    The update cannot be installed because we will be unable to copy some files. This is usually due to inconsistent file permissions.: wp-admin/includes/update-core.php

    Installation failed.

给wp-admin目录加上权限

chmod -R o+rw wp-content

更新时出现

Another update is currently in progress. 在配置表中删除：core_updater.lock 这条数据删除即可。

SELECT * FROM `wp_options` WHERE `option_name` = 'core_updater.lock'

如果还没有解决问题，此时就把整个项目的目录权限加上可读写

chmod -R go+rw wordpress

以上更新亲自测试过，更新成功!!!
