Zabbix错误提示MySQL server has gone away解决
相信细心的同学在使用Zabbix的过程中,会遇到[Z3005] query failed: [2006] MySQL server has gone away 这个错误提示,虽然出现错误提示,但实际并不会影响Zabbix Server的正常使用。那么,这个问题能不能解决呢?本文将带你彻底解决此问题的出现。 1错误现象 22773:20160108:172513.801 [Z3005] query failed: [2006] MySQL server has gone away [select hostid,key_,state,filter,error,lifetime from items where itemid=34993] 22968:20160108:172517.815 [Z3005] query failed: [2006] MySQL server has gone away [select hostid,key_,state,filter,error,lifetime from items where itemid=32057] 2分析 如果你之前没有遇到这个问题,第一想到的应该是去网上搜索,MySQL出现 [2006] MySQL server has gone away,根据网络搜索的结果,会得出以下解决办法: #vim /etc/my.cnf max_allowed_packet=300M wait_timeout=200000 interactive_timeout = 200000 然后重启MySQL,经过测试,该方法无果而终,问题依旧。 3解决办法 继续寻找解决办法,在Zabbix的JIRA里面看到此问题为Zabbix Server的BUG,已在2.5中解决,但对于2.5以下版本,该bug没有修复。 解决办法如下
#vim src/libs/zbxdb/db.c
int zbx_db_connect(char *host, char *user, char *password, char *dbname,char *dbschema, char *dbsocket, int port) {
int ret = ZBX_DB_OK, last_txn_error, last_txn_level;
#if defined(HAVE_IBM_DB2)
char *connect = NULL;
#elif defined(HAVE_MYSQL)
my_bool mysql_reconnect = 1;
#elif defined(HAVE_ORACLE)
char *connect = NULL;
sword err = OCI_SUCCESS;
#elif defined(HAVE_MYSQL)
conn = mysql_init(NULL);
if (NULL == mysql_real_connect(conn, host, user, password, dbname, port, dbsocket, CLIENT_MULTI_STATEMENTS))
{
zabbix_errlog(ERR_Z3001, dbname, mysql_errno(conn), mysql_error(conn));
ret = ZBX_DB_FAIL;
}
if (0 != mysql_options(conn, MYSQL_OPT_RECONNECT, &mysql_reconnect))
zabbix_log(LOG_LEVEL_WARNING, "Cannot set MySQL reconnect option.");
if (ZBX_DB_OK == ret && 0 != mysql_select_db(conn, dbname))
{
zabbix_errlog(ERR_Z3001, dbname, mysql_errno(conn), mysql_error(conn));
ret = ZBX_DB_FAIL; } 注意红色字体的代码 ./configure --host=x86_64-redhat-linux-gnu --build=x86_64-redhat-linux-gnu --program-prefix= --prefix=/usr --exec-prefix=/usr --bindir=/usr/bin --sbindir=/usr/sbin --sysconfdir=/etc --datadir=/usr/sha re --includedir=/usr/include --libdir=/usr/lib64 --libexecdir=/usr/libexec --localstatedir=/var --sharedstatedir=/var/lib --mandir=/usr/share/man --infodir=/usr/share/info --enable-dependency-tracking --enable-server --enable-proxy --enable-java --enable-agent --enable-ipv6 --with-net-snmp --with-libcurl --with-openipmi --with-unixodbc --with-ldap --with-ssh2 --with-libcurl --with-libxml2 --sysconfdir=/etc/zabbix --datadir=/var/lib --enable-server --with-mysql
重新编译完成后,整个世界清静了,问题完美解决! 原创:itnihao
