Here goes the thinking:First,use rpm -qa or apt-cache policy to find the name of the package(s) to remove.Then,use rpm -e or apt-get remove to uninstall the packages.
Detect the os type by bash shell:http://www.doxer.org/learn-linux/linux-shell-centos-debian-ostype/
#centos begin
rpm -qa|grep httpd #under centos it’s httpd,debian apache
if [ $? = '0' ];then
aa=”`rpm -qa|grep httpd`” #get the full-name of the package
rpm -e $aa
fi

#debian begin
apt-cache policy apache2|grep “Installed: 2.” -q
if [ #? = '0'];then
apt-get remove apache2
fi

After you’ve installed proftpd in centos or debian,add user account is the next step.Use groupadd and useradd command,and passwd to set a password,the new user is then ready to use ftp to log in the home directory(set home directory by ‘useradd -d’).
But sometimes,things are not that simple.Now you want the ftp user have specified privileges on some directories,and you are not allowed to change the old mod(for example,directories under /var/www/htdocs).If you encounter this,time for you to use acl(Access Control List) module of linux.
Here is the detailed steps:
groupadd test
useradd -g test -d /var/www/virtual -s /sbin/nologin test #-s /sbin/nologin disallow user to log in the system
passwd test
setfacl -m u:test:rwx /var/www/virtual #test now have mod rwx
getfacl /var/www/virtual

#In /etc/rc.local,type in setfacl -m u:test:rwx /var/www/virtual to run the command at boot time

#If you find no command setfacl,getfacl on your system,use yum install acl(centos),apt-get install acl(debian,ubuntu) to firstly install them.

Use mysqldump command to dump the database sql files,then merge it with site file sources to tar named suffixed by YYYYMMDD(year-month-day).Then use ftp protocal tranfering the tarball to your remote backup server.
Here goes the script:
#!/bin/bash
#wordpress_backup.sh,chmod +x wordpress_backup.sh
YYYY=`date +%Y`
MM=`date +%m`
DD=`date +%d`
filename=”$YYYY$MM$DD”
mysqldump -h localhost -u root -p123456 –default-character-set=utf8 db1>/tmp/db1_${filename}.sql
mysqldump -h localhost -u root -p123456 –default-character-set=utf8 db2>/tmp/db2_${filename}.sql
tar zcvpPf /tmp/doxer_$filename.tar.gz /var/www/virtual/doxer.org /tmp/db1_${filename}.sql db2_${filename}.sql
# to your backup server
ftp -v -n xxx.xxx.xxx.xxx <<EOF
user  [email protected] password
binary
cd backup_sql #change directory on remote backup server
lcd /tmp #change directory on localhost
prompt
mput doxer_$filename.tar.gz #upload tarball
close
bye
EOF

At last,if you want to backup the files three times a week,use crond to accomplish it.Here is the usage: Read more…
