Normal user launches Tomcat

First, create the start user and directory permissions

[Email protected] ~]# Useradd user

[[email protected] ~]# passwd User (passwd)

Use root shutdown

Chown-r user/tomcat (front user name, followed by directory)

chmod U+x/tomcat

Su-user

Then go to the relevant bin directory and start.

Two

SU Switch to User report Unable to set User ID: Resource temporarily unavailable error

The problem is: under the/ETC/SECURITY/LIMITS.D directory, rhel6 and CENTOS6 have a few more files: 90-nproc.config

The contents of this file:

# Default limit for number of user ' s processes to prevent

# Accidental fork bombs.

# See RHBZ #432903 for reasoning.

* Soft Nproc 1024

The limit is 1024, note or 1024 value is changed, save exit, immediate effect, and then try Su to user, problem solving. But why add this file, not clear, there is this directory on Rhel 5, but there is no this file

Of course, your/etc/security/limits.conf configuration of the user allowed to open the file handle number is not too small, right?

Cat/etc/security/limits.conf

User Soft Nproc 4094

User Hard Nproc 32768

User Soft Nofile 2048

User Hard Nofile 131072
