Publish linux services with jsvc

Download commons-daemon-native.tar.gz, which can be obtained from the bin directory of TomcatX.

tar zxvf commons-daemon-native.tar.gz
cd commons-daemon-1.0.13-native-src/unix/

If it is a 64-bit system, you need to modify jsvc-unix.c under native

Modify the declaration of the char array of libcap_locs, otherwise the error that libcap.so cannot be found will be reported in the debug information

static const char *libcap_locs[] = {
"/lib64/libcap.so.2",
"/lib64/libcap.so.1",
"/lib64/libcap.so",
"/lib/libcap.so.2",
"/lib/libcap.so.1",
"/lib/libcap.so",
"/usr/lib64/libcap.so.2",
"/usr/lib64/libcap.so.1",
"/usr/lib64/libcap.so",
"/usr/lib/libcap.so.2",
"/usr/lib/libcap.so.1",
"/usr/lib/libcap.so",
NULL
};

Compile and install

./configure
make
cp jsvc /data0/tomcat/bin

At this point, the jsvc installation is over.

Installation can refer to http://commons.apache.org/daemon/jsvc.html

Let's start making the service of the linux system

Add the service below

chkconfig --add tomcat
chkconfig --list|grep tomcat

Under Centos, if you can see the two processes of father and son, it will be right.

If you have permission problems, please 755 or chown

I hope it will be helpful to my friends, which can solve the problem of Tomcat's startup user permissions and avoid switching users back and forth.

If you have a better way, welcome everyone to discuss and exchange.
