![]() ![]() If everything went ok, you can enable the opt mysql server during startup.ĭisable the old script from running at init. During debuging a server that doesn’t start you can manually issue # /opt/mysql/server-5.6/bin/mysqld_safe -defaults-file=/etc/mysql/my-opt.cnf You did make the data backup, didn’t you ? # /etc/init.d/mysql-opt startĬheck the logs for errors. ![]() NOTE: This will update you current mysql internal tables. Make init script executable # chmod a+x /etc/init.d/mysql-opt Keep a data backup just in case you will need to revert the old data # cp -rp /var/lib/mysql /var/lib/mysql.old Which now is deprecated, it should be replaced by the following two lines: slow-query-log = TRUE Lc-messages-dir = /opt/mysql/server-5.6/shareĪlso if you have this enabled, like I did log_slow_queries = Under the section, modify the following lines: basedir = /opt/mysql/server-5.6 Under the section, add the following line: mysqld = mysqld -defaults-file=/etc/mysql/my-opt.cnf Then, copy /etc/mysql/my.cnf to /etc/mysql/my-opt.cnf and edit: Make it executable # chmod a+x /etc/mysql/debian-start-opt Then, copy /etc/mysql/debian-start to /etc/mysql/debian-start-opt and edit as appropriate: Replace the call to /etc/mysql/debian-start with /etc/mysql/debian-start-opt.usr/bin/mysqld_safe to /opt/mysql/server-5.6/bin/mysqld_safe) Replace calls to mysql binaries with the opt ones (e.g.Replace /etc/mysql/my.cnf with /etc/mysql/my-opt.cnf.Oracle does not provide a repository.ĮDIT: In brief, you can copy the original /etc/init.d/mysql to /etc/init.d/mysql-opt and modify it as appropriate: Yes this is manual, but this is the price you pay to be on the bleeding edge. ![]() Here is another approach compared to empi89 's answer, using a modified mysql init script. Any further information should be available in the very detailed official guide. Now, you should have a mysql installation. When the compile has finished (it will take about an hour), run either sudo make install or sudo checkinstall Now you are ready to run the compile with make and any options that you may add: make Then when the cmake configure has finished and is satisfied (take note of any missing dependencies it mentions if there are any missing ones download them and then delete everything in the bld directory and run the above cmake command again) For that, as noted here, please run (while in the bld folder): cmake -DBUILD_CONFIG=mysql_release. Important documentation is available here on the build process, but what you probably want to do is just use the standard options that the official build uses. At the present time you want mysql-5.6. go down the page, select development releases and then select source code in the box.Ĭd to the folder and create a folder called bld: cd mysql-5.6.7-rcĪt this point it is important to fetch the dependencies with sudo apt-get install build-essential cmake libaio-dev However, as you say you are interested in compiling the latest development version of mysql 5.6, the following instructions should help you:ĭownload the latest development source code from the mysql site and verify the download. There are also no ppas available at the present time (other than the one you have tried), so the following way of compiling mysql-5.6 is actually the easiest and only way at the minute of getting what you want. If you want to use the latest development code you have to download it from the official site, which is better than trying to enable some unstable repository or another. sudo apt-get source mysql-5.5Īs there isn't any other source available by default. Note: Doing it the 'Debian way' (as you mention) will only get you mysql-5.5 and not 5.6: i.e. Step 4 is needed if you would like to automatically enable swap file after each reboot.You can of course install everything required for Mysql-5.5 from the repositories in both 12.04 and 12.10, but the following should help you get Mysql-5.6 installed.įirstly, I should try installing the deb file from the official site in Software Centre or Gdebi, as those programs resolve dependencies, dpkg doesn't. Run dd if=/dev/zero of=/swapfile bs=1M count=1024Īdd this line /swapfile swap swap defaults 0 0 to /etc/fstab I assume you have AWS Account with a Micro instance running. Steps below show how to make a swap space for your Micro instance. ![]() Actually performance wise is better to enable swap. So if you want to avoid the crash you may need to setup a swap space for your micro instance. After a long search about MySQL, Micro Instance and Memory Managment I found out there is no default SWAP space for Micro instance. Since Micro instances have only 613MB of memory, MySQL crashed every now and then. I have a Amazon EC2 Linux Micro instance. I copied the contents if the page does not loadsĪmazon EC2 Micro Instance Swap Space - Linux InnoDB: Cannot allocate memory for the buffer poolĪdding a swap page might solve the problem. I met the same problem on my micro instance. ![]()
