这几天在centos下装mysql，这里记录一下安装的过程，方便以后查阅
Mysql5.5.37安装需要cmake，5.6版本开始都需要cmake来编译，5.5以后的版本应该也要装这个。
安装cmake
[root@local ~]# wget http://www.cmake.org/files/v2.8/cmake-2.8.12.2.tar.gz
[root@local ~]# tar xvf cmake-2.8.12.2.tar.gz
[root@local ~]# cd cmake-2.8.12.2
[root@local cmake-2.8.12.2]#./bootstrap
[root@local cmake-2.8.12.2]# make
[root@local cmake-2.8.12.2]# make install
</div>
安装mysql
[root@local ~]# wget http://cdn.mysql.com/Downloads/MySQL-5.5/mysql-5.5.37.tar.gz
[root@local ~]# tar xvf mysql-5.5.37.tar.gz
[root@local ~]# cd mysql-5.5.37
[root@local mysql-5.5.37]# cmake ./
</div>
可能还会报这个错，没有就跳过
CMake Error at cmake/readline.cmake:83(MESSAGE):
Curses library not found. Pleaseinstall appropriate package,
remove CMakeCache.txt and rerun cmake.On Debian/Ubuntu, package name islibncurses5-dev, on Redhat and derivates it is ncurses-devel.
Call Stack (most recent call first):
cmake/readline.cmake:127 (FIND_CURSES)
cmake/readline.cmake:217 (MYSQL_USE_BUNDLED_LIBEDIT)
CMakeLists.txt:355 (MYSQL_CHECK_READLINE
-- Configuring incomplete, errors occurred!
See also "/root/my/mysql-5.5.37/CMakeFiles/CMakeOutput.log".
See also"/root/my/mysql-5.5.37/CMakeFiles/CMakeError.log".
</div>
说明centos系统没有ncurses-devel
[root@local ~]# wget http://invisible-island.net/datafiles/release/ncurses.tar.gz
[root@local ~]# cd ncurses-5.9
[root@local ncurses-5.9]#./configure
[root@local ncurses-5.9]# make
[root@local ncurses-5.9]# make install
</div>
再删除刚才编译生成的 CMakeCache.txt 文件，否则无法进行下一步
[root@local mysql-5.5.37]# rm -f CMakeCache.txt
</div>
继续编译mysql
[root@local ~]# cmake ./
[root@local ~]# make
[root@local ~]# make install
</div>
这样，mysql默认将成功安装到/usr/local/mysql
创建mysql用户组
[root@local ~]# groupadd mysql
[root@local ~]# useradd –r –g mysql mysql
[root@local ~]# chown –R mysql.mysql /usr/local/mysql
</div>
启动mysql
[root@local ~]# /usr/local/mysql/bin/mysqld_safe --user=mysql
</div>
这里可能会发生错误，没有就跳过：
FATAL ERROR: Could not find./bin/my_print_defaults
If you compiled from source, you need torun 'make install' to
copy the software into the correct locationready for operation.
If you are using a binary release, you musteither be at the top
level of the extracted archive, or pass the --basedir option
pointing to that location.
</div>
解决方法：
[root@local ~]# /usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
</div>
再启动mysql
[root@local ~]# /usr/local/mysql/bin/mysqld_safe --user=mysql
</div>
注册mysql服务，开机自动启动
1.设置mysql配置文件到/etc目录
[root@local ~]# cp /usr/local/mysql/support-files/my-medium.cnf/etc/my.cnf
</div>
2.设置mysql开机自启
[root@local ~]# cp/usr/local/mysql/support-files/mysql.server /etc/init.d/mysql
[root@local ~]# chmod +x /etc/init.d/mysql
[root@local ~]# /sbin/chkconfig --add mysql
</div>
3.启动mysql服务
[root@local ~]# service mysql start
</div>
测试mysql是否安装成功
[root@local ~]# /usr/local/mysql/bin/mysql -u root -p
