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安装须要cmake，5.6版本号開始都须要cmake来编译，5.5以后的版本号应该也要装这个。

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


 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 ./


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".


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


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


继续编译mysql

[root@local ~]# cmake ./
[root@local ~]# make
[root@local ~]# make install


这样，mysql默认将安装成功到/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


启动mysql

[root@local ~]# /usr/local/mysql/bin/mysqld_safe --user=mysql


这里可能会错误发生，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.


解决方法：

[root@local ~]# /usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data


再启动mysql

[root@local ~]# /usr/local/mysql/bin/mysqld_safe --user=mysql



注冊mysql服务，开机自己主动启动

 1.设置mysql配置文件到/etc文件夹

[root@local ~]# cp /usr/local/mysql/support-files/my-medium.cnf/etc/my.cnf


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


3.启动mysql服务

[root@local ~]# service mysql start


 

測试mysql是否成功安装

[root@local ~]# /usr/local/mysql/bin/mysql -u root -p
Enter password:
