编译安装MySQL

1、安装MySQL需要的依赖包和编译软件

（1）安装MySQL需要的依赖包

#yum install ncurses-devel libaio-devel -y

（2）安装编译MySQL需要的软件

#ls -lh cmake-2.8.8.tar.gz

#tar xf cmake-2.8.8.tar.gz

#cd cmake-2.8.8

#./configure

#gmake && gmake install

或者直接yum安装

#yum install cmake -y

2、开始安装MySQL

（1）建立MySQL用户帐号

#useradd -s /sbin/nologin -M mysql

(2)获取MySQL软件包

http://mirrors.sohu.com/

（3）采用编译方式安装MySQL

#tar xf mysql-5.5.49.tar.gz

#cd mysql-5.5.49

cmake . -DCMAKE_INSTALL_PREFIX=/application/mysql-5.5.49\-DMYSQL_DATADIR=/application/mysql-5.5.49/data \-DMYSQL_UNIX_ADDR=/application/mysql-5.5.49/tmp/mysql.sock\-DDEFAULT_CHARSET=utf8 \-DDEFAULT_COLLATION=utf8_general_ci \-DEXTRA_CHARSETS=gbk,gb2312,utf8,ascii \-DENABLED_LOCAL_INFILE=ON \-DWITH_INNOBASE_STORAGE_ENGINE=1 \-DWITH_FEDERATED_STORAGE_ENGINE=1 \-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \-DWITHOUT_EXAMPLE_STORAGE_ENGINE=1 \-DWITHOUT_PARTITION_STORAGE_ENGINE=1 \-DWITH_FAST_MUTEXES=1 \-DWITH_ZLIB=bundled \-DENABLED_LOCAL_INFILE=1 \-DWITH_READLINE=1 \-DWITH_EMBEDDED_SERVER=1 \-DWITH_DEBUG=0

#make && make install

#ln -s /application/mysql-5.5.49/ /application/mysql

数据库配置文件

#mkdir -p /data/3306/data

数据库启动文件

#vim /data/3306/mysql

修改文件权限

#chown -R mysql.mysql /data

#find /data -name mysql|xargs chmod 700

配置全局路径

#echo 'export PATH=/application/mysql/bin:$PATH' >>/etc/profile

#source /etc/profile

初始化数据库

#cd /application/mysql/scripts

./mysql_install_db --basedir=/application/mysql --datadir=/data/3306/data --user=mysql

启动数据库

/data/3306/mysql start

登录数据库

#mysql -S /data/3306/mysql.sock

修改数据库登录密码

#mysqladmin -u root -S /data/3306/mysql.sock password '123456'

#mysql -uroot -p123456 -S /data/3306/mysql.sock

降权启动

#find /data -type f -name "mysql"|xargs chmod 700

#find /data -type f -name "mysql" -exec chown root.root {} \;

设置开机自启

#echo "#mysql multi instances">>/etc/rc.local

#echo "/data/3306/mysql start">>/etc/rc.local

删除不需要的数据库

>select user,host from mysql.user;

>drop user 'root'@'::1';

>drop user ''@'db01';

>drop user 'root'@'db01';

>drop user ''@'localhost';

>select user,host from mysql.user;

>flush privileges;
