使用Artful MySQL模块出错 总是报错: root@gitlab:/opt# newlispnewLISP v.10.6.0 64-bit on Linux IPv4/6 UTF-8 libffi, options: newlisp -h (load /opt/mysql.lsp)ERR: string expected in function import : libmysqlclient 结果发现是Ubuntu 12.04下安
使用Artful MySQL模块出错总是报错:
root@gitlab:/opt# newlisp newLISP v.10.6.0 64-bit on Linux IPv4/6 UTF-8 libffi, options: newlisp -h > (load "/opt/mysql.lsp") ERR: string expected in function import : libmysqlclient
结果发现是Ubuntu 12.04下安装的libmysqlclient.so的路径不正常,用 find / -name查找, 将真实路径添加到mysql.lsp文件中
;;; Find the libmysqlclient library on this system (setf is-64-bit nil) (let ((paths '("/usr/lib/libmysqlclient.so" "/usr/lib/x86_64-linux-gnu/libmysqlclient.so" ;;here "/usr/lib64/mysql/libmysqlclient.so" "/usr/local/mysql/lib/libmysqlclient.dylib" "/opt/local/lib/libmysqlclient.dylib" "/sw/lib/libmysqlclient.dylib")))
好了,加载模块成功:
> (load "/opt/mysql.lsp") MAIN
可是连接数据库报错,原来是没有跟上newllisp 10.6.0的步伐。 现在获取最新的未测试的代码:
git clone https://gist.github.com/10490156.git
> (load "/opt/10490156/mysql.lsp") MAIN > _MYSQL:is-64-bit true > (setf db (Mysql)) (Mysql 10710960) > (:connect db "localhost" "root" "770328" "mysql") true > (:query db "show tables") (MysqlResult 10812080) > (exit)
似乎可用了,具体还要等作者完成测试。

通过PHP网页界面添加MySQL用户可以使用MySQLi扩展。步骤如下:1.连接MySQL数据库,使用MySQLi扩展。2.创建用户,使用CREATEUSER语句,并使用PASSWORD()函数加密密码。3.防止SQL注入,使用mysqli_real_escape_string()函数处理用户输入。4.为新用户分配权限,使用GRANT语句。
