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

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
