CENTOS 7-安装JDK后$ PATH错误 [英] CENTOS 7 - $PATH incorrect after installing jdk

问题描述

我是Linux操作系统的新手，并且已在centos7上安装了jdk.

I'm new with Linux OS and I have installed jdk on centos7.

现在，每次我登录时，都会收到以下错误消息:

Now each time I login, I get following error message:

/usr/libexec/grepconf.sh: line 5: grep: command not found
-bash: /home/centos/.bash_profile: line 13: syntax error near unexpected token `newline'
-bash: /home/centos/.bash_profile: line 13: `export PATH=$PATH:/opt/jdk1.8.0_192/bin:/opt/jdk1.8.0_192/jre/bin:/usr/local/sbin:/usr/sbin:/home/centos/.local/bin:/home/centos/bin:/usr/bin/grep>'

所有命令均未找到"

我找到此信息以更新路径: https://unix.stackexchange.com/questions/302743/centos-7-所有命令都找不到-除了cd

I find this post to update path: https://unix.stackexchange.com/questions/302743/centos-7-all-command-not-found-except-cd

然后我用以下命令更新路径:

and I update path with this command:

PATH=/usr/local/bin:/usr/bin:bin

所以现在 sudo nano/home/centos/.bash_profile 命令，我在bash_profile文件中具有以下内容:

So now with sudo nano /home/centos/ .bash_profile command I have following content in bash_profile file:

# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
    . ~/.bashrc
fi

 # User specific environment and startup programs

 PATH=$PATH:$HOME/.local/bin:$HOME/bin

 export PATH
 export PATH=$PATH:/opt/jdk1.8.0_192/bin:/opt/jdk1.8.0_192/jre/bin:/usr/local/sbin:/usr/sbin:/home/centos/.local/bin:/home/centos/bin:/usr/bin/grep>

什么是问题?我该如何解决所描述的错误?

What is problem ? How can I solve the error described ?

第一次编辑，以回答@航海问题:

1rst edit in order to answer @nautical questions:

.bash_profile文件的内容:

Here the content of .bash_profile file :

# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/.local/bin:$HOME/bin

export PATH
export PATH=$PATH:/opt/jdk1.8.0_192/bin:/opt/jdk1.8.0_192/jre/bin:/usr/local/sbin:/usr/sbin:/home/centos/.local/bin:/home/centos/bin:/usr/bin/grep

这里是grepconf的内容:

Here the content of grepconf :

#!/bin/sh

case "$1" in
    -c | --interactive-color)
        ! grep -qsi "^COLOR.*none" /etc/GREP_COLORS
        ;;
    *)
        echo >&2 "Invalid / no option passed, so far only -c | --interactive-color is supported."
        exit 1
        ;;
esac

第二次编辑，以回答评论中的问题:

2nd Edit in order to answer questions in comment :

这里ldd/usr/bin/grep命令输出:

here ldd /usr/bin/grep command output:

linux-vdso.so.1 =>  (0x00007fff769b8000)
    libpcre.so.1 => /lib64/libpcre.so.1 (0x00007f0454df3000)
    libc.so.6 => /lib64/libc.so.6 (0x00007f0454a26000)
    libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f0454809000)
    /lib64/ld-linux-x86-64.so.2 (0x000055ce09e0c000)

这是ls -l/lib64/ld *的结果

Here the result of ls -l /lib64/ld*

[centos@serveur-1 ~]$ ls -l /lib64/ld*
-rwxr-xr-x 1 root root 163400 Jan 29 18:55 /lib64/ld-2.17.so
lrwxrwxrwx 1 root root     10 Feb 20 21:51 /lib64/ld-linux-x86-64.so.2 -> ld-2.17.so

每次我注销后，我都会登录，除了某些命令，我​​总是得到找不到命令":

And each time I logout, then I login, I get always "command not found" except for some command like for example :

java -version

因此，每次我必须键入"PATH =/usr/local/bin:/usr/bin:bin/"(在此站点上找到答案)，并且每次我键入echo $ PATH时，输出都会越来越复杂:

So each time I must type "PATH=/usr/local/bin:/usr/bin:bin/" (answer found on this site) and each time I type echo $PATH, the output is more and more complex :

[centos@serveur-1 ~]$ echo $PATH
$PATH:/opt/jdk1.8.0_192/bin:/opt/jdk1.8.0_192/jre/bin:/usr/local/sbin:/usr/sbin:/home/centos/.local/bin:/home/centos/bin:/opt/jdk1.8.0_192/bin:/opt/jdk1.8.0_192/jre/bin:/usr/local/sbin:/usr/sbin:/home/centos/.local/bin:/home/centos/bin:/usr/bin/grep

我想$ PATH内容刚登录后就坏了.

I suppose $PATH content is bad just after login.

那我该如何彻底解决呢?

So how can I solved it definitively ?

对@tripleee的第三次修改:这里的.bashrc文件内容:

Third edit for @tripleee : Here .bashrc file content :

[centos@serveur-1 ~]$ sudo nano /home/centos/.bashrc
  GNU nano 2.3.1                  File: /home/centos/.bashrc

# .bashrc

# Source global definitions
if [ -f /etc/bashrc ]; then
        . /etc/bashrc
fi

# Uncomment the following line if you don't like systemctl's auto-paging feature:
# export SYSTEMD_PAGER=

# User specific aliases and functions

它谈论/etc/bashrc，所以这是它的内容:

It talks about /etc/bashrc, so this is its content:

[centos@serveur-1 ~]$ sudo nano /etc/bashrc
  GNU nano 2.3.1                   File: /etc/bashrc

# /etc/bashrc

# System wide functions and aliases
# Environment stuff goes in /etc/profile

# It's NOT a good idea to change this file unless you know what you
# are doing. It's much better to create a custom.sh shell script in
# /etc/profile.d/ to make custom changes to your environment, as this
# will prevent the need for merging in future updates.

# are we an interactive shell?

当您来自"Windows世界"时，很难理解这种机制.

It's quite difficult to understand this mechanism when you come from "Windows world"...

推荐答案

通过如下更新.bash_profile来解决:

Solved by updating .bash_profile as following:

# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
    . ~/.bashrc
fi

# User specific environment and startup programs 


PATH=$PATH:$HOME/.local/bin:$HOME/bin:/usr/local/bin:/usr/bin:/bin:/opt/jdk1.8.0_192/bin:/opt/jdk1.8.0_192/jre/bin

export PATH
