OpenVzからLXCに移行

参考

• Linux Container - Proxmox VE

Migrate container from OpenVZ to Linux container
copy the backup file in /var/lib/vz/template/cache/

注意点

• ZFS上でコンテナの作成、復元はできません。
• Permission error w/ sockets inside CT since migration to PVE 4.1 | Page 2 | Proxmox Support Forum
  • socketのパーミッションが755になる問題あり

755

$ ls -l /var/lib/mysql/mysql.sock
srwxr-xr-x 1 mysql mysql 0 Feb  3 16:43 /var/lib/mysql/mysql.sock

• 力技で回避したい場合は以下

/etc/rc.d/init.d/mysql

 case "$mode" in
   'start')
     # Start daemon
 
     # Safeguard (relative paths, core dumps..)
     cd $basedir
 
     echo $echo_n "Starting MySQL"
     if test -x $bindir/mysqld_safe
     then
       # Give extra arguments to mysqld with the my.cnf file. This script
       # may be overwritten at next upgrade.
       $bindir/mysqld_safe --datadir="$datadir" --pid-file="$mysqld_pid_file_path" $other_args >/dev/null 2>&1 &
       wait_for_pid created "$!" "$mysqld_pid_file_path"; return_value=$?
 
       # Make lock for RedHat / SuSE
       if test -w "$lockdir"
       then
         touch "$lock_file_path"
       fi
 
+      chmod 777 /var/lib/mysql/mysql.sock
       exit $return_value
     else
       log_failure_msg "Couldn't find MySQL server ($bindir/mysqld_safe)"
     fi
     ;;

sshログインが成功しない場合

• [SOLVED] - Problems migrating OpenVZ containers Proxmox 2->4 (ssh PTY allocation request failed) | Proxmox Support Forum

ssh PTY allocation request failed

対応

/etc/rc.local

  #!/bin/sh
  #
  # This script will be executed *after* all the other init scripts.
  # You can put your own initialization stuff in here if you don't
  # want to do the full Sys V style init stuff.

+ rm -f /dev/ptmx && ln -s /dev/pts/ptmx /dev/ptmx
  touch /var/lock/subsys/local

• OS再起動しsshログインができることを確認
