centos mysql 安装以及远程登录的开启

1.先到官网下载以下包，并解压编译安装

./configure

make 

make install

bison
cmake
make
bzr
2.开始搞mysql

解压mysql-5.5.25.tar.gz
tar zxvf mysql-5.5.25.tar.gz
cd mysql-5.5.25
cmake . \
-DCMAKE_INSTALL_PREFIX=/mysql/mysqldir \
-DMYSQL_DATADIR=/mysql/mysqldir/data \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DMYSQL_TCP_PORT=3306 \
-DMYSQL_UNIX_ADDR==/mysql/mysqldir/data/mysql.sock \
-DMYSQL_USER=mysql \
-DWITH_DEBUG=0

报错(如无报错直接make & make install 即可)：

缺少包：ncurses-devel

解决：rpm -ivh ncurses-devel*.rpm

    或者   yum install ncurses-devel*.rpm

rm -f CMakeCache.txt

cmake . \

-DMYSQL_USER=mysql \
-DWITH_DEBUG=0
make
make install

完成后进入MYSQL安装目录
cd /mysql/mysqldir
cp support-files/my-huge.cnf /etc/my.cnf
vi /etc/my.cnf
将数据目录和套接字文件修改为实际值.
修改权限

chown mysql:mysql /etc/my.cnf
chown -R mysql:mysql /mysql/mysqldir

切换用户进入安装目录

su - mysql
cd /mysql/mysqldir
cp scripts/mysql_install_db .
./mysql_install_db
启动MYSQL
bin/mysqld_safe &
