Linux – AC_CONFIG_MACRO_DIRS([m4]) conflicts with ACLOCAL.AMFLAGS=-I build-aux/m4

背景：编译 gRPC
报错：AC_CONFIG_MACRO_DIRS([m4]) conflicts with ACLOCAL.AMFLAGS=-I build-aux/m4
解决：

find . -name \*.m4|xargs dos2unix
find . -name \*.ac|xargs dos2unix
find . -name \*.am|xargs dos2unix

find . -name \*.m4|xargs dos2unix

find . -name \*.ac|xargs dos2unix

find . -name \*.am|xargs dos2unix

Linux – 修改用户的主目录

来自：这里

新装的系统，新建用户（user1）后，用户的主目录在：/home/user1，想修改到：/data/

如下，把user1对应的目录改为/data：

[root@localhost mysql]# vim /etc/passwd
user1:x:541:541::/data:/bin/bash
user2:x:542:542::/home/user2:/bin/bash

[root@localhost mysql]# vim /etc/passwd

user1:x:541:541::/data:/bin/bash

user2:x:542:542::/home/user2:/bin/bash

vsftpd – 修改 vsftpd 的默认根目录

来自：这里

用yum安装好vsftpd之后，用户登录进来后目录是在：/usr/home/usr1，想改到：/data/

修改配置文件，添加这二/三行代码：

[root@localhost mysql]# vim /etc/vsftpd/vsftpd.conf
...
# 非匿名用户登录后的路径
local_root=/data/
# 下面这行不知道干啥的
chroot_local_user=YES
# 匿名用户登录后的路径，这一行没加
anon_root=/var/www/html/

[root@localhost mysql]# vim /etc/vsftpd/vsftpd.conf

...

# 非匿名用户登录后的路径

local_root=/data/

# 下面这行不知道干啥的

chroot_local_user=YES

# 匿名用户登录后的路径，这一行没加

anon_root=/var/www/html/

MySQL – 在 Linux 上安装并更改数据文件位置

服务器环境：某型Linux，已有yum

参考：一，二

安装：

yum install mysql

1	yum install mysql

启动：

[root@localhost ~]# service mysqld start
Starting mysqld:                                           [  OK  ]

1 2	[root@localhost ~]# service mysqld start Starting mysqld: [ OK ]

启动后发现，数据库的数据文件默认存放在：/var/lib/mysql，由于实际需要，需要改到：/data/my[……]

Linux – 用md5sum校验文件

这里是抄袭源。

用tar打包文件后传到另一服务器上解压报错中断。

于是对比两个文件的MD5。先用md5sum分别计算两个服务器文件的MD5：

[root@VM_centos ~]# md5sum test.tar.gz > test_md5.txt
[root@VM_centos ~]# cat test_md5.txt
fa1b8d4dbbc9712f667748cadefe681a  test.tar.gz

[root@VM_centos ~]# md5sum test.tar.gz > test_md5.txt

[root@VM_centos ~]# cat test_md5.txt

fa1b8d4dbbc9712f667748cadefe681a test.tar.gz

然后再对比，果，然，不，一，样。

END。

邮件服务 – CentOS 搭建邮件服务

那么接下来呢，想在服务器上收发邮件。“收”这个操作先不管，首先做到能“发”。

照旧，原文在此。

首先，安装服务。

1、这里说的发送邮件，是要用到“sendmail”，所以先检查是否安装。

2、没安装的话，就装。

照旧，这是搬家贴（原文在这里哟）。自己操作了一遍。

1、安装Subversion

[root@VM_centos /]# yum install subversion

2、找一下安装位置

[root@VM_centos /]# rpm -ql subversion
/etc/bash_completion.d
/etc/bash_completion.d/subversion
/etc/rc.d/init.d/svnserve
/etc/subversion
/usr/bin/svn
/usr/bin/svnadmin
/usr/bin/svndumpfilter
/usr/bin/svnlook
/usr/bin/svnserve
/usr/bin/svnsync
/usr/bin/svnversion
...
...
...

[root@VM_centos /]# rpm -ql subversion

/etc/bash_completion.d

/etc/bash_completion.d/subversion

/etc/rc.d/init.d/svnserve

/etc/subversion

/usr/bin/svn

/usr/bin/svnadmin

/usr/bin/svndumpfilter

/usr/bin/svnlook

/usr/bin/svnserve

/usr/bin/svnsync

/usr/bin/svnversion

...

然后可以稍微看一下帮助

Telnet – CentOS 安装 Telnet

1、检查系统版本——虽然我也不知道查这玩意干嘛但是既然别人都查了那么我也写在这里吧╮（￣▽￣）╭
