3.查看依赖：

rpm -q -scripts MariaDB-server-10.1.22-1.x86_64

 

preinstall scriptlet (using /bin/sh):
# Check if we can safely upgrade. An upgrade is only safe if it‘s from one
# of our RPMs in the same version family.

installed=`rpm -q --whatprovides mysql-server 2> /dev/null`
if [ $? -eq 0 -a -n "$installed" ]; then
installed=`echo "$installed"|sed -n 1p`
vendor=`rpm -q --queryformat=‘%{VENDOR}‘ "$installed" 2>&1`
version=`rpm -q --queryformat=‘%{VERSION}‘ "$installed" 2>&1`
myvendor=‘Monty Program AB‘
myversion=‘10.1.22‘

old_family=`echo $version | sed -n -e ‘s,^\([1-9][0-9]*\.[0-9][0-9]*\)\..*$,\1,p‘`
new_family=`echo $myversion | sed -n -e ‘s,^\([1-9][0-9]*\.[0-9][0-9]*\)\..*$,\1,p‘`

[ -z "$vendor" ] && vendor=‘<unknown>‘
[ -z "$old_family" ] && old_family="<unrecognized version $version>"
[ -z "$new_family" ] && new_family="<bad package specification: version $myversion>"

error_text=
if [ "$vendor" != "$myvendor" ]; then
error_text="$error_text
The current MariaDB server package is provided by a different
vendor ($vendor) than $myvendor. Some files may be installed
to different locations, including log files and the service
startup script in /etc/init.d/.
"
fi

if [ "$old_family" != "$new_family" ]; then
error_text="$error_text
Upgrading directly from MySQL $old_family to MariaDB $new_family may not
be safe in all cases. A manual dump and restore using mysqldump is
recommended. It is important to review the MariaDB manual‘s Upgrading
section for version-specific incompatibilities.

fi

if [ -n "$error_text" ]; then
cat <<HERE >&2

******************************************************************
A MySQL or MariaDB server package ($installed) is installed.
$error_text
A manual upgrade is required.

- Ensure that you have a complete, working backup of your data and my.cnf
files
- Shut down the MySQL server cleanly
- Remove the existing MySQL packages. Usually this command will
list the packages you should remove:
rpm -qa | grep -i ‘^mysql-‘

You may choose to use ‘rpm --nodeps -ev <package-name>‘ to remove
the package which contains the mysqlclient shared library. The
library will be reinstalled by the MariaDB-shared package.
- Install the new MariaDB packages supplied by $myvendor
- Ensure that the MariaDB server is started
- Run the ‘mysql_upgrade‘ program

This is a brief description of the upgrade process. Important details
can be found in the MariaDB manual, in the Upgrading section.

rpm -e --noscripts MariaDB-server-10.1.22-1.x86_64
