1.MySQL 5.7内存优化:
performance_schema_max_table_instances=400
table_definition_cache=400
performance_schema=off
innodb_buffer_pool_chunk_size=64M
innodb_buffer_pool_size=64M
2.bbr:
echo "net.core.default_qdisc=fq" >> /etc/sysctl.conf
echo "net.ipv4.tcp_congestion_control=bbr" >> /etc/sysctl.conf
sysctl -p
lsmod | grep bbr
3.swap的调整:
临时调整vm.swappiness参数为5
sudo sysctl vm.swappiness=5
永久调整 vm.swappiness参数为1(优先使用物理内存,迫不得已使用swap)
curl -sS -O https://raw.githubusercontent.com/woniu336/open_shell/main/vm.sh && chmod +x vm.sh && ./vm.sh
禁用:
sudo swapoff -a
4.一键DD:
