如何锁定MYSQL内存在物理内存里?_ITPUB博客

|

MYSQL 8.0 这个参数是 OFF 这个参数是啥意思呢? 按英文单词理解是 锁定在内存意思.突然想起来是因为 周报巡检时主库有使用SWAP内存 而从库却使用更多 使用脚本查看SWAP 进程排序 for i in ` cd /proc;ls |grep "^[0-9]"|awk ' $0 >100'` ; do awk '/Swap:/{a=a+$2} END {if(a>0) { print ' " $i" ',a/1024,"Mb"}}' /proc/ $i/smaps; done |sort -k2nr 结果是MYSQLD 使用2.9GB SWAP 官网参数说明 先在MY.CNF配置文件搞搞 locked_in_memory=ON locked_in_memory=1 结果 MYSQL起不来, 查看报错日志说 不认得该参数. 丢! 真是的 上面官网最后一句英文意思是启动的选项. 其实做进配置文件也是一样的.
