Description of problem:
After opened chrome browser, this message appears on screen.
SELinux is preventing /opt/google/chrome/chrome from append, open access on the file /home/lewish/libpeerconnection.log.

*****  Plugin restorecon (99.5 confidence) suggests  *************************

If 您希望修正標籤。 
/home/lewish/libpeerconnection.log 預設標籤應為 user_home_t。
Then 您可以執行 restorecon。
Do
# /sbin/restorecon -v /home/lewish/libpeerconnection.log

*****  Plugin catchall (1.49 confidence) suggests  ***************************

If 您認為 chrome 就預設值應擁有 libpeerconnection.log file 的 append open 存取權。
Then 您應將此回報為錯誤。
您可產生本機模組，以允許這項存取。
Do
現在透過執行以下指令來允許此存取：
# grep chrome /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
