Linux

将下面的行加入 /etc/security/limits.conf

*               soft    nofile             8192
*               hard    nofile             8192

将下面的行加入 /etc/sysctl.conf ,提高kernel性能,可以不添加。

net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_tw_recycle = 1
net.ipv4.ip_local_port_range = 1024 65000
fs.file-max = 65000

运行 sudo sysctl -p 将对 /etc/sysctl.conf 的修改生效。

Mac

查看max files:

$ sudo launchctl limit
    cpu         unlimited      unlimited
    filesize    unlimited      unlimited
    data        unlimited      unlimited
    stack       8388608        67104768
    core        0              unlimited
    rss         unlimited      unlimited
    memlock     unlimited      unlimited
    maxproc     709            1064
    maxfiles    256            unlimited

修改max file到8192:

$ sudo launchctl limit maxfiles 8192 unlimited
$ sudo launchctl limit
    cpu         unlimited      unlimited
    filesize    unlimited      unlimited
    data        unlimited      unlimited
    stack       8388608        67104768
    core        0              unlimited
    rss         unlimited      unlimited
    memlock     unlimited      unlimited
    maxproc     709            1064
    maxfiles    8192           10240

# 注:
$ sudo launchctl limit maxfiles unlimited  # 也可以直接设置为unlimited
