Linux下安装mysql的方法详解

前提:安装cmake（mysql5.5以后是通过cmake来编译的)到网络去下载一下吧,安装方法如下:

[root@webserver soft]#tar -xzvf cmake-2.6.4.tar.gz 

[root@webserver cmake-2.6.4]#./configure --prefix=/usr/local/cmake 

[root@webserver cmake-2.6.4]#make

[root@webserver cmake-2.6.4]#make install

#创建用户和用户组与赋予数据存放目录权限

[root@webserver ~]#groupadd mysql
[root@webserver ~]#useradd -g mysql mysql

#解压
[root@webserver soft]# tar -zxvf mysql-5.5.29.tar.gz

#安装mysql
[root@webserver mysql]# cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/data/mysql/database -
DMYSQL_UNIX_ADDR=/usr/local/mysql/data/mysqld.sock -DWITH_INNOBASE_STORAGE_ENGINE=1 -DENABLED_LOCAL_INFILE=1 -
DMYSQL_TCP_PORT=3306 -DEXTRA_CHARSETS=all -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -

DMYSQL_UNIX_ADDR=/usr/local/mysql/data/mysql.sock -DMYSQL_USER=mysql -DWITH_DEBUG=0

(注意:)

   如果cmake时出现 command not found 的字样时,请在终端执行下面命令

 [root@webserver mysql]# export PATH=/usr/local/cmake/bin:$PATH

[root@webserver mysql]# make
[root@webserver mysql]# makeinstall

#设置权限
[root@webserver mysql]#chown -R mysql:mysql /usr/local/mysql/

#初始化mysqldb
[root@webserver mysql]# ./scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql/database

#设置数据库权限:
[root@webserver mysql]# chown mysql:mysql -R /data/mysql/database

#配置mysql

[root@webserver support-files]# cp my-large.cnf /etc/my.cnf
[root@webserver support-files]# cp mysql.server /etc/init.d/mysqld
[root@webserver support-files]# chmod +x /etc/init.d/mysqld

#启动mysql

[root@webserver ~]# /etc/init.d/mysqld start

#连接数据库

[root@webserver mysql]# /usr/local/mysql/bin/mysql -u root -p
