phpMyAdmin uses Twig by default from the version 4.8.0.

   I updated phpMyAdmin from 4.7.9 to 4.8.0 the day before yesterday. Although they wrote that ‘it is possible to install phpMyAdmin from our own Composer repository.’ on the official download page, I still uses the manually installation in my own way. After updating, I was surprised with a folder named tmp in my phpMyAdmin root directory. But it’s not a malicious but a proper one by phpMyAdmin.


How to connect to MariaDB secure server from phpMyAdmin and WordPress.


   After “MariaDB with Secure Connections.”, my SQL server has Secure Connections. Now I have to add some options to phpMyAdmin and WordPress settings.
   Their versions are MariaDB 10.2.9 win 32-bit, phpMyAdmin 4.7.4 and WordPress 4.8.2 on Windows 7 32-bit HE SP1.

everyday life

I’ve updated to phpMyAdmin4.6.6.


   I’ve updated to phpMyAdmin4.6.6. After that, the new version gave me “OpenSSL error: error:0607A082:digital envelope routines:EVP_CIPHER_CTX_set_key_length:invalid key length” at HOME when I logged in.
   This is maybe because of this 👉 $cfg[‘Servers’][$i][‘ssl_verify’].

   The page says “Disabling the certificate verification defeats purpose of using SSL. This will make the connection vulnerable to man in the middle attacks.”, but my SQL server and phpMyAdmin don’t accept accesses from outside of NAT router and the user is only me. So, as my temporal workaround, I added the next line to my

$cfg['Servers'][$i]['ssl_verify'] = false;

WordPress4.6 has come.


   Actually, I failed once. My Web Browser status bar told ‘done’, but the progressing page showed only two lines. Besides, the update marker didn’t have gone. So I tried again and had ‘Another update is currently in progress’.

   I accessed via FTP but couldn’t find .maintenance file. I looked for a solution on the internet and reached ‘Get rid of Another update is currently in progress’.


Memorandum #18.


   Recently I updated some server apps.

    Update information      Edit(Jul.21)
  1. From ActivePerl- to ActivePerl-
    Last time I installed ActivePerl- But now they doesn’t provide an msi file. Then I tried to install ActivePerl-, but it gave me an error like the below.

    Error 1723. There is a problem with this Windows Installer package. A DLL required for this install to complete could not be run. Contact your support personnel or package vendor.  Action CheckInstallDir, entry: CheckInstallDirNoBox, library: C:UsersUserIDAppDataLocalTempMSIXXXX.tmp

Memorandum #15.


   As PHP7.0.3 was released, I updated to it the day before yesterday. Here is ChangeLog. My server OS is Windows7 HE SP1 x86, so I downloaded
   The new php.ini-production doesn’t have difference from 7.0.2’s except some comments. If you need more information about php.ini configuration, see ‘Migrating from PHP 5.5.16 to PHP 5.6.0 on Windows’.


Memorandum #13.


   Being too busy with writing HTTP/2, I’ll also write about it, which is I moved to MariaDB 10.1.8. Not to update it. Besides, I found PHP5.6.15, phpMyAdmin4.5.1 and ActivePerl- yesterday, so I took care of them all.


phpMyAdmin 4.5.0 is released.


   They released phpMyAdmin on September 23, on September 24 and on September 25. What new releases in sequence! Ha-ha!! Here is the ChangeLogs. The has a tons of improvements by RFE(Request for enhancement) or so. The and are bugfix versions.


phpMyAdmin 4.3.0 is released.


   They released phpMyAdmin 4.3.0 on December 5 and 4.3.1 on December 8. So I updated to 4.3.1 from yesterday. Here is the ChangeLogs. The 4.3.0 has a tons of improvements by RFE(Request for enhancement). The 4.3.1 is a bugfix version.

   I downloaded a, extracted it, copied my old to the phpmyadmin folder made from extracting, and uploaded all of them to the server (See “To create a Wamp-like Web Server in Windows7-#3.“).

   By the way, when I compared the new with my old one(=Ver.4.2.x), I found a line was lost and a line was added.

At /* Storage database and tables */ area
   The lost line.
     // $cfg[‘Servers’][$i][‘designer_coords’] = ‘pma__designer_coords’;

   The added line.
     // $cfg[‘Servers’][$i][‘central_columns’] = ‘pma__central_columns’;

4.3.1 alerts
4.3.1 alerts
   So, when I logged on the new phphmyadmin as root at the first time, I got “The phpMyAdmin configuration storage is not completely configured, some extended features have been deactivated. Find out why. Or alternately go to ‘Operations’ tab of any database to set up it there”.

   By clicking ‘Find out why’, I got the alerts like the right image.

   I had instructions, too.

     Quick steps to setup advanced features:

     Create the needed tables with the ./examples/create_tables.sql.
     Create a pma user and give access to these tables.
     Enable advanced features in configuration file (, for example by starting
     Re-login to phpMyAdmin to load the updated configuration file.

   I did the followings.

  1. Log on the new version with the old as root.
  2. Add the ALTER privilege to the controluser(Default : pma) on the database phpmyadmin.
  3. Import the new create_tables.sql. If you change the database name(Default : phpmyadmin) and the controluser name(Default : pma), you need to customize the sql file before import. See “Configuration storage“.
  4. Log out.
  5. Edit the old
    • Delete the line.
           $cfg[‘Servers’][$i][‘designer_coords’] = ‘pma__designer_coords’;
    • Add the line.
           $cfg[‘Servers’][$i][‘central_columns’] = ‘pma__central_columns’;
  6. Log on as root, again.
  7. Drop the table pma__designer_coords.

   That’s it.

   About pma__central_columns, see central_columns.


First VPS #3 : How to configure LAMP on CentOS7.


   Yesterday, they announced Hayabusa 2 Launch rescheduled again. The new schedule for it is at 13:22:04 on December 3(JST). I hope good weather which makes third time lucky aha.

   I’ll create a LAMP server on CentOS7 with SELinux enforcing in VPS.
   But before this, I did the three four things.

  1. $ sudo vi /etc/pam.d/su
    Then, uncomment the next line.
    #auth required use_uid –>> auth required use_uid
    Now the OS permits for only the users in Wheel Group can become root by ‘su’ command.
  2. $ sudo vi /etc/aliases
    Then, uncomment the last line of the file and change the user name.
    #root: marc –>> root: centos
    $ sudo newaliases
    By this, the user centos can get root’s mail.
  3. Check up on the time zone.
    $ sudo timedatectl status
    Everything is OK.
    $ sudo systemctl status chronyd.service
    I had “System clock wrong by 1.088336 seconds, adjustment started” in the result, so I edited /etc/chrony.conf.
    $ sudo vi /etc/chrony.conf
    In the file I found “# Use public servers from the project.”, and I went to I added the lines with ‘+’ at their head and deleted ‘-’s by the instructions.
    +server iburst
    +server iburst
    +server iburst
    +server iburst
    server iburst
    server iburst
    server iburst
    server iburst
    Then, restart the service and check again.
    $ sudo systemctl restart chronyd.service
    $ sudo systemctl status chronyd.service
    Now everything is OK.
  4. For automatic updates.
    $ sudo yum install yum-cron
    $ sudo vi /etc/yum/yum-cron.conf
     line# 20: apply_updates = no –>> apply_updates = yes
    $ sudo systemctl start yum-cron.service
    $ sudo systemctl enable yum-cron.service

1 Install Apache Httpd   2 Install MariaDB   3 Install PHP
4 Install phpMyAdmin   5 Install vsftpd

||Install Apache Httpd||

  1. $ sudo yum install httpd
    The installed version is httpd.x86_64 2.4.6-18.el7.centos.
  2. Edit /etc/httpd/conf/httpd.conf.
    $ sudo vi /etc/httpd/conf/httpd.conf
    Show line numbers by ‘:set nu’.

    • line# 42: Listen 80 –>> Listen Server_global_IP:80
    • line# 86: ServerAdmin root@localhost –>> ServerAdmin My_email_address
    • line# 95: #ServerName –>> ServerName VPS_DomainName:80
    • line# 119: DocumentRoot "/var/www/html" –>> DocumentRoot "/home/centos/www/html"
    • line# 124: <Directory "/var/www"> –>> <Directory "/home/centos/www">
    • line# 131: <Directory "/var/www/html"> –>> <Directory "/home/centos/www/html">
    • line# 144: Options Indexes FollowSymLinks –>> Options FollowSymLinks
    • line# 151: AllowOverride None –>> AllowOverride FileInfo Indexes Limit
      In my case, this change is for WordPress use.
    • line# 164: DirectoryIndex index.html –>> DirectoryIndex index.php index.html
  3. Note) The location of exstra.conf files: /etc/httpd/conf.d
    The extra conf files by default: autoindex.conf, userdir.conf, welcome.conf
  4. Note2) The location of module.conf files: /etc/httpd/conf.modules.d/
  5. Note3) I do not rotate log files but the Apache Httpd seems to be able to make it automatically (See /var/log/httpd/ after more than one-day server running). From when can it do this?? Or is this CentOS7’s own feature?
  6. Usually ~userid has the permission 700, but it needs 701 for httpd accessibility. This information on the userdir.conf.
    $ chmod 701 centos
  7. I set the DocumentRoot to an user’s home directory, so I need to tell it to SELinux and to allow httpd to access User Home Directory. This information is on httpd_selinux(8). However, when I tried to read it, CentOS7 said it’s empty, oops!!
    See online httpd_selinux(8).
    $ sudo setsebool -P httpd_enable_homedirs on
    $ sudo systemctl start httpd.service
    I had the error message “Job for httpd.service failed. See ‘systemctl status httpd.service’ and ‘journalctl -xn’ for details.” when I first started httpd.service. Because I forgot to create ‘www’ and ‘html’ directories. So I made them as the user centos.
    [centos@localhost ~]$ mkdir www
    [centos@localhost ~]$ cd www
    [centos@localhost www]$ mkdir html
    Check the directories context.
    $ ls -Z
    drwxrwxr-x. test test unconfined_u:object_r:httpd_user_content_t:s0 www
    $ ls -Z
    drwxrwxr-x. test test unconfined_u:object_r:httpd_user_content_t:s0 html
  8. $ sudo systemctl start httpd.service again.
  9. $ sudo firewall-cmd --permanent --zone=public --add-service=http
    Httpd Testing page
    Httpd Testing page
    $ sudo firewall-cmd --reload
    $ sudo systemctl enable httpd.service
    Note4) Each Well-Known-Port seems to be set by default. So you don’t need firewall-cmd command for port 80.
  10. Access http://VPS_DomainName/. You can see a page like the right image.
