We recently have been unfortunate to experience an accidental "CHOWN /" event on our centos7 server. We have recovered and have working all production facing pages (php, apache, client side session/php session and mysql) all up and working. We still have file permission issues on a number of packages causing a few issues (that we can see): * phpmyadmin not working * security flaws due to permission mismatch This job is to return the server to a usable state, and then quote for ongoing SYS Admin work (ie. this has brought this problem and dependancy to the FORE, we need to move to a dedicated person to help with SYS admin). ON hand for any questions - between 7am and 11pm AEST preferred for work, so I can engage via chat etc when needed.
