由於公司運行的tomcat下catalina.out越來越大，所以怕以後對系統有影響，所以採用cronolog來將catalina.out每天生成一份
1.下載cronolog-1.6.2.tar.gz官網打不開，但是在CU上找到了
http://download.chinaunix.net/download.php?id=3457&ResourceID=1851
2.安裝cronolog
tar -zxf cronolog-1.6.2.tar.gz
cd cronolog-1.6.2
./configure --prefix=/home/xxxx/cronolog(因爲是非root用戶，所以解壓到用戶home下，如果是root可不加此參數)
make && make install
3.修改catalina.sh(此文件在tomca目錄下bin文件夾)
需要修改3處：
1）將：
if [ -z "$CATALINA_OUT" ] ; then
CATALINA_OUT="$CATALINA_BASE"/logs/catalina.out
fi
改爲：
if [ -z "$CATALINA_OUT" ] ; then
CATALINA_OUT="$CATALINA_BASE"/logs/catalina.out.%Y-%m-%d
fi
2）註釋 touch "$CATALINA_OUT"，約370行
# touch "$CATALINA_OUT"
3）將：
if [ "$1" = "-security" ] ; then
if [ $have_tty -eq 1 ]; then
echo "Using Security Manager"
fi
shift
eval "\"$_RUNJAVA\"" "\"$LOGGING_CONFIG\"" $LOGGING_MANAGER $JAVA_OPTS $CATALINA_OPTS \
-Djava.endorsed.dirs="\"$JAVA_ENDORSED_DIRS\"" -classpath "\"$CLASSPATH\"" \
-Djava.security.manager \
-Djava.security.policy=="\"$CATALINA_BASE/conf/catalina.policy\"" \
-Dcatalina.base="\"$CATALINA_BASE\"" \
-Dcatalina.home="\"$CATALINA_HOME\"" \
-Djava.io.tmpdir="\"$CATALINA_TMPDIR\"" \
org.apache.catalina.startup.Bootstrap "$@" start \
>> "$CATALINA_OUT" 2>&1 "&"
else
eval "\"$_RUNJAVA\"" "\"$LOGGING_CONFIG\"" $LOGGING_MANAGER $JAVA_OPTS $CATALINA_OPTS \
-Djava.endorsed.dirs="\"$JAVA_ENDORSED_DIRS\"" -classpath "\"$CLASSPATH\"" \
-Dcatalina.base="\"$CATALINA_BASE\"" \
-Dcatalina.home="\"$CATALINA_HOME\"" \
-Djava.io.tmpdir="\"$CATALINA_TMPDIR\"" \
org.apache.catalina.startup.Bootstrap "$@" start \
>> "$CATALINA_OUT" 2>&1 "&"
fi
改爲：
if [ "$1" = "-security" ] ; then
if [ $have_tty -eq 1 ]; then
echo "Using Security Manager"
fi
shift
eval "\"$_RUNJAVA\"" "\"$LOGGING_CONFIG\"" $LOGGING_MANAGER $JAVA_OPTS $CATALINA_OPTS \
-Djava.endorsed.dirs="\"$JAVA_ENDORSED_DIRS\"" -classpath "\"$CLASSPATH\"" \
-Djava.security.manager \
-Djava.security.policy=="\"$CATALINA_BASE/conf/catalina.policy\"" \
-Dcatalina.base="\"$CATALINA_BASE\"" \
-Dcatalina.home="\"$CATALINA_HOME\"" \
-Djava.io.tmpdir="\"$CATALINA_TMPDIR\"" \
org.apache.catalina.startup.Bootstrap "$@" start \
2>&1 |/home/xxx/cronolog/sbin/cronolog "$CATALINA_OUT" & #(注意cronolog實際安裝路徑)
else
eval "\"$_RUNJAVA\"" "\"$LOGGING_CONFIG\"" $LOGGING_MANAGER $JAVA_OPTS $CATALINA_OPTS \
-Djava.endorsed.dirs="\"$JAVA_ENDORSED_DIRS\"" -classpath "\"$CLASSPATH\"" \
-Dcatalina.base="\"$CATALINA_BASE\"" \
-Dcatalina.home="\"$CATALINA_HOME\"" \
-Djava.io.tmpdir="\"$CATALINA_TMPDIR\"" \
org.apache.catalina.startup.Bootstrap "$@" start \
2>&1 |/home/xxx/cronolog/sbin/cronolog "$CATALINA_OUT" & #(注意cronolog實際安裝路徑)
fi
最後，重啓tomcat即可
