使用Shell脚本批量执行SQL脚本

#!/bin/bash

# 配置数据库和用户信息
DATABASES=("Database1" "Database2" "Database3" "Database4" "Database5")
USERS=("user1" "user2" "user3" "user4" "user5" "user6")
PASSWORD="your_password" # 假设所有用户使用同一个密码
SQL_SCRIPT="upgrade_script.sql" # SQL 脚本路径

# 数据库执行函数
execute_sql() {
    local db=$1
    local user=$2
    local sql=$3
    echo "Executing script on database: $db, user: $user..."
    mysql -h localhost -u "$user" -p"$PASSWORD" "$db" < "$sql"
    if [[ $? -ne 0 ]]; then
        echo "Error: Execution failed on $db for user $user" >&2
        return 1
    fi
    echo "Success: Executed script on $db for user $user"
}

# 主循环：对每个数据库和用户执行 SQL
for db in "${DATABASES[@]}"; do
    for user in "${USERS[@]}"; do
        execute_sql "$db" "$user" "$SQL_SCRIPT"
    done
done

echo "All scripts executed successfully!"

[client]
user=user1
password=your_password

mysql Database1 < upgrade_script.sql

for db in "${DATABASES[@]}"; do
    for user in "${USERS[@]}"; do
        execute_sql "$db" "$user" "$SQL_SCRIPT" &
    done
done
wait

USE target_db;

-- 示例：为用户 user1 授予 EXECUTE 权限
GRANT EXECUTE ON DATABASE target_db TO user1;

-- 示例：如果还需要 SELECT、INSERT 权限：
GRANT SELECT, INSERT, UPDATE, DELETE ON DATABASE target_db TO user1;

-- 在目标数据库下为每个用户循环授予权限
USE target_db;
