禁用开启启动项
systemctl disable firewalld.service
2.检查服务器cpu是否支持SSE4.2指令集(向量化执行需要)
grep -q sse4_2 /proc/cpuinfo && echo "SSE 4.2 supported" || echo "SSE 4.2 not supported"3.调整操作系统最大进程数和文件句柄
vim /etc/systemd/system.conf
DefaultLimitNOFILE=65535
#DefaultLimitAS=
DefaultLimitNPROC=65535
修改需要重启才能生效
最大打开文件数立即生效：
ulimit -n 655354.创建目录
