1,创建用户及密码：
CREATE USER 'user'@'%' IDENTIFIED BY 'password';
2，创建数据库：
create database PDB_chengang default character set utf8 collate utf8_general_ci;
3，分配权限：
GRANT ALL ON PDB_chengang.* TO 'user'@'%';
4，使配置即时生效:
flush privileges;
5，按条件检索：
select * from deploy_deploypool where id=388;
6，更新一条数据库条目：
update deploy_deploypool set name='2452345 ' where id=388;
7，用另外表里的相等条目来更新本表里的条目：
update deploy_deploypool a set jenkins_number = (select jenkins_number from version_deployversion b where b.nginx_url=a.nginx_url);
8，导出数据库数据：
mysqldump -uuser -p PDB > PDB.20160303.sql
9，导入数据库数据：
source /root/dir/PDB.20160303.sql;
10，批量删除数据表：
#!/bin/bash # 删除mysql中所有表 # 示例： # Usage: ./script user password dbnane # Usage: ./script user password dbnane server-ip # Usage: ./script user password dbnane mysql.nixcraft.in # --------------------------------------------------- MUSER="$1" MPASS="$2" MDB="$3" MHOST="localhost" [ "$4" != "" ] && MHOST="$4" # 设置命令路径 MYSQL=$(which mysql) AWK=$(which awk) GREP=$(which grep) # help if [ ! $# -ge 3 ] then echo "Usage: $0 {MySQL-User-Name} {MySQL-User-Password} {MySQL-Database-Name} [host-name]" echo "Drops all tables from a MySQL" exit 1 fi # 连接mysql数据库 $MYSQL -u $MUSER -p$MPASS -h $MHOST -e "use $MDB" &>/dev/null if [ $? -ne 0 ] then echo "Error - 用户名或密码无效，无法连接mysql数据库" exit 2 fi TABLES=$($MYSQL -u $MUSER -p$MPASS -h $MHOST $MDB -e 'show tables' | $AWK '{ print $1}' | $GREP -v '^Tables' ) # make sure tables exits if [ "$TABLES" == "" ] then echo "Error - 在数据库中 $MDB 未发现相关表" exit 3 fi # let us do it for t in $TABLES do echo "Deleting $t table from $MDB database..." $MYSQL -u $MUSER -p$MPASS -h $MHOST $MDB -e "drop table $t" done
慢慢积累，慢慢感觉。。。
