编译
make
make install
建立用户
useradd -d /home/mysql -s /bin/nologin mysql
建立目录
mkdir -p /data/mysqldata
mkdir -p /data/mysqldata/data
mkdir -p /data/mysqldata/innodb/data
mkdir -p /data/mysqldata/innodb/log
mkdir -p /data/mysqllog/binlog/

chown -R mysql.mysql /data1/mysql*
权限
chown -R mysql.mysql /data/mysql*
初始化DB
chmod +x mysql_install_db.sh
如果失败，需要修改脚本中basedir
scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/data/mysqldata/data --user=mysql
#mysql
/usr/bin/mysqld_safe --user=mysql &
#backup file
0 4 * * * cd /data/databackup;/bin/sh db_bk.sh
#del file
0 4 * * * cd /data/databackup;/bin/sh del_sql_file.sh
#多实例
#scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/data/mysql_3307/data --user=mysql --defaults-file=/etc/my_3307.cnf
#./mysqld_safe --defaults-file=/etc/my_3307.cnf --user=mysql &
#关闭MySQL
#./mysqladmin -uroot -p -S /data/mysql_3307/mysql.sock shutdown
