MYSQL_OPT_READ_TIMEOUT (argument type: unsigned int *)The timeout in seconds for each attempt to read from the server. There are retries if necessary, so the total effective timeout value is three times the option value. You can set the value so that a lost connection can be detected ...
昨天有人在群里问, MySQL是否可以设置读写超时(非连接超时), 如果可以就可以避免一条SQL执行过慢, 导致PHP超时错误. 这个, 其实可以有. 只不过稍微要麻烦点. Filed in MySQL/PostgreSQL, PHP应用, PHP源码分析 with 14 Comments Sidebar Laruence PHP开发组核心成员, Zend顾问, PHP7及PHP8 JIT核心作者. Yaf...
The MYSQL_OPT_READ_TIMEOUT and MYSQL_OPT_WRITE_TIMEOUT options to mysql_options() work for all TCP/IP connections since 4.1.22/5.0.25/5.1.12. From the manual page athttp://dev.mysql.com/doc/refman/5.1/en/mysql-options.html:
首先, 在libmysql中, 是提供了MYSQL_OPT_READ_TIMEOUT设置项的, 并且libmysql中提供了设置相关设置项的API, mysql_options: int STDCALL mysql_options(MYSQL*mysql,enummysql_optionoption,constvoid*arg) { DBUG_ENTER("mysql_option"); DBUG_PRINT("enter",("option: %d",(int) option)); ...

MYSQL_OPT_READ_TIMEOUT 是 MySQL c api 客户端中用来设置读取超时时间的参数。在 MySQL 的官方文档中，该参数的描述是这样的：MYSQL_OPT_READ_TIMEOUT (argument type: unsigned int *)The timeout in seconds for each attempt to read from the server. There are retries if necessary, so ...
define('MYSQL_OPT_WRITE_TIMEOUT', 12); } //设置超时 $mysqli = mysqli_init(); $mysqli->options(MYSQL_OPT_READ_TIMEOUT, 3); $mysqli->options(MYSQL_OPT_WRITE_TIMEOUT, 1); //连接数据库 $mysqli->real_connect("localhost", "root", "root", "test"); ...
net_read_timeout 和net_write_timeout是数据库会话创建好之后mysql server端使用的读写超时。如果读取或者写入操作在等待了达到超时后服务器认为客户端连接断开,执行错误处理。 而slave_net_timeout是slave的io线程使用客户端C API连接master时候,调用mysql_options()来设置MYSQL_OPT_CONNECT_TIMEOUT,MYSQL_OPT_READ...
-You got a timeout from the TCP/IP connection on the client side. This may happen if you have been using the commands: mysql_options(…, MYSQL_OPT_READ_TIMEOUT,…) or mysql_options(…, MYSQL_OPT_WRITE_TIMEOUT,…). In this case increasing the timeout may help solve the problem. ...
