Centos5.5安装Mysql5.5过程_MySQL

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

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 ~]# wgethttp://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

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

这里可能会发生错误，没有就跳过：

FATAL ERROR: Could not find./bin/my_print_defaultsIf you compiled from source, you need torun 'make install' tocopy the software into the correct locationready for operation.If you are using a binary release, you musteither be at the toplevel of the extracted archive, or pass the --basedir optionpointing 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

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

测试mysql是否安装成功

[root@local ~]# /usr/local/mysql/bin/mysql -u root -pEnter password: Welcome to the MySQL monitor.Commands end with ; or /g.Your MySQL connection id is 1Server version: 5.5.37 Source distribution Copyright (c) 2000, 2014, Oracle and/or itsaffiliates.
