Centos logrotate not rotating logs daily - centos7

Question

I have a problem i configured daily logrotation for catalina.out in Centos7 but it is not rotated , if force run logrotate it rotates catalina but not automatically on daily basis.
logrotate.d/tomcat configfile:
/usr/local/tomcat7/logs/catalina.out
{
daily
rotate 30
missingok
compress
copytruncate
}
logrotate.conf:
# see "man logrotate" for details
# rotate log files daily
daily
# keep 4 weeks worth of backlogs
rotate 4
# create new (empty) log files after rotating old ones
create
# use date as a suffix of the rotated file
dateext
# uncomment this if you want your log files compressed
#compress
# RPM packages drop log rotation information into this directory
include /etc/logrotate.d
# no packages own wtmp and btmp -- we'll rotate them here
/var/log/wtmp {
monthly
create 0664 root utmp
minsize 1M
rotate 1
}
/var/log/btmp {
missingok
monthly
create 0600 root utmp
rotate 1
}
# system-specific logs may be also be configured here.
logrotate status/debug:
rotating pattern: /usr/local/tomcat7/logs/catalina.out
after 1 days (30 rotations)
empty log files are rotated, old logs are removed
considering log /usr/local/tomcat7/logs/catalina.out
log does not need rotating (log has been already rotated)

In it's default state tomcat uses the log4j
You should have a file at /etc/tomcat/log4j.properties which contains the configuration for the log management.
The default config is (taken from a test box):
log4j.rootLogger=debug, R
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=${catalina.home}/logs/tomcat.log
log4j.appender.R.MaxFileSize=10MB
log4j.appender.R.MaxBackupIndex=10
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n
log4j.logger.org.apache.catalina=DEBUG, R
log4j.logger.org.apache.catalina.core.ContainerBase.[Catalina].[localhost]=DEBUG, R
log4j.logger.org.apache.catalina.core=DEBUG, R
log4j.logger.org.apache.catalina.session=DEBUG, R
Based on that config the logs will automatically rotate when they grow to 10MB in size, and will keep a maximum of 10 old logs.
You can change these settings as you wish and there are a couple of good guides here and here which explain all the options, and show how to change to a rolling appender which may be more useful for your needs.
Also log4j takes care of the rotation but if you are doing something like tail -f cat.out and the log rotates you will need to re-tail the file to continue watching it else it will just appear to stop mid way (much like the other logs do)
Remember to remove any config you tried to apply via logrotate so things don't go wrong later on!
To have a daily rotation you need to use these settings;
DailyRollingFileAppender
DailyRollingFileAppender rotates log files based on frequency of time
allowing customization upto minute. Date Patterns allowed as part of
the Appender are as follows:
yyyy-MM Roll over to new log file beginning on first day of every month
yyyy-ww Roll over to new log file beginning on first day of every week
yyyy-MM-dd Roll over daily
yyyy-MM-dd-a Roll over on midday and midnight
yyyy-MM-dd-HH Roll over every hour
yyyy-MM-dd-HH-mm Roll over every minute
That would give a config of:
log4j.rootLogger=INFO, fileLogger
log4j.appender.fileLogger.layout=org.apache.log4j.PatternLayout
log4j.appender.fileLogger.layout.ConversionPattern=%d [%t] %-5p (%F:%L) - %m%n
log4j.appender.fileLogger.File=example.log
log4j.appender.fileLogger=org.apache.log4j.DailyRollingFileAppender
log4j.appender.fileLogger.datePattern='.'yyyy-MM-dd-HH-mm
