This post documents the steps of installing MySQL from source code, and the resolutions to serveral issues in installing. The steps here are specific to 64-bit Ubuntu 14.04.1 LTS, and MySQL source code is 5.7.5-m15. But I think most of them can also work on your system.
Download MySQL source code
wget http://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.5-m15.tar.gz
Install GCC/G++/Make/CMake
If your system has not installed gcc/g++/make/cmake yet, please install them first. The following commands should be able to get your system installed correct and proper versions.
apt-get install update apt-get install gcc apt-get install g++ apt-get install make apt-get install cmake cmake-gui
Other dependencies
If the system prompts "Curses library not found. Please install appropriate package, remove CMakeCache.txt and rerun cmake.On Debian/Ubuntu, package name is libncurses5-dev, on Redhat and derivates it is ncurses-devel." when you execute "cmake .", please run apt-get to install the library.
apt-get install libncurses5-dev
If the error "Bison executable not found in PATH.", please run the command below.
apt-get install bison
Install MySQL
# groupadd mysql useradd -r -g mysql mysql # tar zxvf mysql-VERSION.tar.gz cd mysql-VERSION # cmake . -DDOWNLOAD_BOOST=1 -DWITH_BOOST=/root/boost -DENABLE_DOWNLOADS=1 make make install # cd /usr/local/mysql chown -R mysql . chgrp -R mysql . # from 5.7.5, the --datadir option is mandatory. bin/mysql_install_db --datadir=/usr/local/mysql/data # chown -R root . chown -R mysql data # Open the MySQL config file vi /etc/mysql/my.cnf
Change the default values of basedir, datadir, and lc-message-dir to the following values.
basedir = /usr/local/mysql datadir = /usr/local/mysql/data lc-messages-dir = /usr/local/mysql/share # this setting will avoid the error "[ERROR] Can‘t find error-message file ‘/usr/share/mysql/errmsg.sys‘".
If your MySQL log is under /var/log/mysql, please execute the following commands. The commands will prevent the error "touch: cannot touch /var/log/mysql/error.log: No such file or directory" from happening when you run "bin/mysqld_safe --user=mysql &".
mkdir /var/log/mysql chown -R mysql:mysql /var/log/mysql
Run mysqld_safe to try to start mysql. Don‘t omit the ‘&‘. :-)
bin/mysqld_safe --user=mysql &
If you see the following errors in /var/log/mysql/error.log, open /etc/mysql/my.cnf and edit the variables like below.
[ERROR] unknown variable ‘key_buffer=16M‘
vi /etc/mysql/my.cnf, change ‘key_buffer=16M‘ to ‘key_buffer_size=16M‘.
[ERROR] unknown variable ‘myisam-recover=BACKUP‘
Comments out this line ‘myisam-recover=BACKUP‘ in /etc/mysql/my.cnf with a ‘#‘.
Reset password for root
First, you need login mysql server with the random password generated by mysql_install_db. You can find the password in the file /root/.mysql_secret.
/usr/local/mysql/bin/mysql -u root -p
Then, use Set Password statement to set new password.
mysql> set password = password(‘your password‘);
Add MySQL Server executables to system PATH
Create a file mysql.sh under /etc/profile.d/ directory,
touch /etc/profile.d/mysql.sh vi /etc/profile.d/mysql.sh
and add the following lines to the file.
#!/bin/bash
if ! echo ${PATH} | /bin/grep -q /usr/local/mysql/bin ; then
PATH=/usr/local/mysql/bin:${PATH}
fi
Use the following command to add the path to the current shell.
source /etc/profile.d/mysql.sh
Use echo $PATH to check if the script works. "/usr/local/mysql/bin" should be in the output.
echo $PATH
Add MySQL Server libraries to the shared library cache
touch /etc/ld.so.conf.d/mysql.conf echo "/usr/local/mysql/lib" > /etc/ld.so.conf.d/mysql.conf ldconfig
Set MySQL Server service
cp support-files/mysql.server /etc/init.d/mysql service mysql start
