[Maria-discuss] why stdout? -> [Note] /usr/libexec/mysqld (mysqld 10.0.20-MariaDB) starting as process 115096
by Reindl Harald 05 Jul '20

Aug 6 12:24:24 testserver mysqld: 150806 12:24:24 [Note] /usr/libexec/mysqld (mysqld 10.0.20-MariaDB) starting as process 115096 ... why is this now stdout instead mysql logs? on systemd based distributions that spits now to the global syslog and finally on machines restarting 2 instances every hour for backup reasons it annoys until 10.0.19 or 10.0.20 that was not this way

No, MariaDB doesn't have a passwordless root user that mysqladmin needs to issue the flush-logs command. I suspect that there was originally a root user with socket authentication this system. Even after fixing this the mysqld may not be able to create new logs in /var/log/. I'd normally expect /var/log/mysql to be owned by the mysql user and its configuration to log the error to a file in this directory. > I've > added some extra information gathering, so we'll see how it runs tonight. > > > On 27 March 2017 at 22:34, Daniel Black <daniel.black(a)au1.ibm.com > <mailto:daniel.black@au1.ibm.com>> wrote: > > I think you'll find that the mysql user don't have permissions to create > a new file in /var/log/.

On this error I'm not sure. Looks to be some sort of inheritance hierarchy that is different in musl from glibc et al. I'd chase them up to see who is violating the C++ spec. Have you tried using buildroot? It has a stable 10.1 version that is kept up to date and it has the one outstanding uclibc patch (that is waiting in jira https://jira.mariadb.org/browse/MDEV-10841) On 26/03/17 02:52, Lucian Cristian wrote: > Hi > > I'm trying to cross compile (any 10.* versions) using musl and uClibc++ > for a LEDE/Openwrt system and I have problems with these errors: > > > staging_dir/target-x86_64_musl/usr/include/uClibc++/associative_base:444:8: > error: 'void std::__base_associative<Key, ValueType, Compare, > Allocator>::swap(std::__base_associative<Key, ValueType, Compare, > Allocator>&) [with Key = dict_foreign_t*;

[Maria-discuss] MariaDB memory usage

Hi, Hi, I have MariaDB 10.1.19 with 1 GB of RAM on (AWS RDS) and another one with 4 GB of RAM (production instance). Memory usage keeps on increasing on both. Free memory goes below 50MB.

I am giving the InnoDB engine status for your reference below, I would be happy to get any pointers on this issue. ===================================== 2017-03-31 10:53:08 2b25f6ec2700 INNODB MONITOR

[Maria-discuss] mysqladmin - flush failed: Unknown error
by Matthew Pash 27 Mar '17

27 Mar '17

Hi, We've got some database servers running MariaDB 10.1.22, and are having issues with logrotate. Specifically, after it runs, it leaves a 0 byte file and continues writing log data to mysqld.log.1 Manually running logrotate in verbose mode shows this error from mysqladmin when it tries to run -flush_logs: /usr/bin/mysqladmin: flush failed; error: 'Unknown error' error: error running non-shared postrotate script for /var/log/mysqld.log of '/var/log/mysqld.log ' set default create context Has anyone seen this before? It doesn't look like a permissions error - the logs are created fine if you run systemctl restart mariadb. Thanks, ~Matt -- *Matthew* Senior Systems Administrator, IT Services University of Bristol

[Maria-discuss] Can not build MariaDB 10.0.30 and 10.1.22 with Visual Studio 2013
by Ayano Kosaka 22 Mar '17

22 Mar '17

Hi, I can not build MariaDB 10.0.30 and 10.1.22 with Visual Studio 2013 on Windows 7 Pro 64 bit. `identifier "int64_t" is undefined` occurs at `storage/xtradb/btr/btr0cur.cc`. It is probably caused by the following merge commit: [Merge branch 'merge-xtradb-5.6' into 10.0] https://github.com/MariaDB/server/commit/83da1a1e572d67588b66724b34fdb7f079… Before this commit, `ib_int64_t` (the typedef, which wraps compiler differences, in `../include/univ.i`) is used instead of `int64_t`. This error does not occur on VS2015, because it has `int64_t`. But VS2013 does not have `int64_t`. Were the supported compilers changed? Or, a bug or my environmental problem? Regards, Ayano Kosaka
