Linux operation: executable file, library file path settings!

I am often asked this question. How do I set the path?
Why can't I use the executable file after I leave the executable file folder?
Why is it always wrong when I use export?

There are a lot of problems. Here we will introduce a very direct and simple method. In fact, the operation is very simple. Anyone familiar with Linux should know that it is a little help to those who are not very familiar with Linux.

Operating System: opensuse 11.1 64-bit

1. Set the executable file path. We can directly modify the system file for implementation, which is very simple:
Run the following command on the terminal:

1. Btazuo:/etc# Cd/etc
2. Btazuo:/etc# Vim Profile

There are a lot of things in the profile file. Find the path:

In

1. ForDirIn/Usr/X11/bin/

Add your own executable files under this line.

2. Set the library file path. The system file is still modified as follows:

1. Btazuo :~# Cd/etc
2. Btazuo:/etc# Vim lD. So. conf

Inside

In

1. Include/etc/lD. So. conf. d/*. conf

Before you add your library file, that is, the path of the Lib file, it will be OK.

Restart and OK, haha.

Operating System: centos 58

The executable file path is still in/etc/profile:

1 #/etc/profile 2 3 # system wide environment and startup programs, for login setup 4 # functions and aliases go in/etc/bashrc 5 6 pathmunge () {7 if! Echo $ PATH |/bin/egrep-Q "(^ |:) $1 ($ |:)"; then 8 if ["$2" = "after"]; then 9 Path = $ path: $1 10 else 11 Path = $1: $ PATH 12 fi 13 fi 14} 15 16 # KSh workaround 17 if [-z "$ EUID"-a-x/usr/bin/ID]; then 18 EUID = 'id-U' 19 uid = 'id-Ru '20 FI 21 22 # Path manipulation 23 if ["$ EUID" = "0"]; then 24 pathmunge/sbin 25 pathmunge/usr/sbin 26 pathmunge/usr/local/sbin 27 fi
 

# Add the desired executable file path to then after Path manipulation, such as/usr/local/share/XXX/bin.

System library path, consistent with the above:

[Root @ localhost etc] # ll LD *-RW-r -- 1 Root 9028 Feb 23 2012 LDAP. conf-RW-r -- 1 Root 115468 Dec 9 :07 lD. so. cache-RW-r -- 1 Root 28 Oct 8 2006 lD. so. coninto. so. conf. d: total 32-r -- r -- 1 Root 324 Dec 5 kernelcap-2.6.18-308.24.1.el5.conf-r -- r -- 1 Root 324 Feb 22 2012 kernelcap-2.6.18-308.el5.conf-rw-r -- r -- 1 Root 15 Feb 14 2012 mysql-i386.conf-rw-r -- r -- 1 Root 17 May 10 2012 openais-athlon.conf-rw-r -- r -- 1 Root 20 Feb 24 2012 qt-i386.conf-rw-r -- r -- 1 Root 276 Dec 9 vmware-tools-libraries.conf-rw-r -- r -- 1 Root 21 Nov 21 xulrunner-32.conf [root @ localhost etc] # [root @ localhost etc] # cd lD. so. conf. d/[root @ localhost lD. so. conf. d] # lltotal 32-r -- r -- 1 Root 324 Dec 5 kernelcap-2.6.18-308.24.1.el5.conf-r -- r -- 1 Root 324 Feb 22 2012 kernelcap-2.6.18-308.el5.conf-rw-r -- r -- 1 Root 15 Feb 14 2012 mysql-i386.conf-rw-r -- r -- 1 Root 17 May 10 2012 openais-athlon.conf-rw-r -- r -- 1 Root 20 Feb 24 2012 qt-i386.conf-rw-r -- r -- 1 Root 276 Dec 9 vmware-tools-libraries.conf-rw-r -- r -- 1 Root root 21 Nov 21 xulrunner-32.conf [root @ localhost lD. so. conf. d] # Cat mysql-i386.conf/usr/lib/MySQL

To add a library file path, you only need to add a CONF file in LD. So. conf. D: to specify the path, such as the mysql-i386.conf above, it specifies the path. This is because:

There is only one sentence in the file lD. So. conf:

 
1 include lD. So. conf. d/*. Con
