1.vm.max_map_count

1.1 修改 /etc/sysctl.conf

只添加最后vm值即可，sysctl -p /etc/sysctl.conf

net.ipv4.conf.all.accept_redirects=0
net.ipv4.tcp_tw_reuse=1
net.ipv4.tcp_tw_recycle=1
net.ipv4.tcp_fin_timeout=5
net.ipv4.tcp_keepalive_time=60
net.ipv4.ip_local_port_range=21000 61000
fs.file-max=6553500
kernel.sem=250 32000 100 128
vm.max_map_count = 262144

# sudo sysctl -p /etc/sysctl.conf
net.ipv4.conf.all.accept_redirects = 0
net.ipv4.tcp_tw_reuse = 1
sysctl: cannot stat /proc/sys/net/ipv4/tcp_tw_recycle: No such file or directory
net.ipv4.tcp_fin_timeout = 5
net.ipv4.tcp_keepalive_time = 60
net.ipv4.ip_local_port_range = 21000 61000
fs.file-max = 6553500
kernel.sem = 250 32000 100 128
vm.max_map_count = 262144
