linux偶爾遇到gradle 編譯時(shí), 發(fā)生"Too many open files" 導(dǎo)致編譯失敗.
網(wǎng)上說(shuō)了一堆 ulimit的, 不頂用. 以下方法 實(shí)測(cè)有用.
參考:
https://superuser.com/questions/1200539/cannot-increase-open-file-limit-past-4096-ubuntu
// 操作步驟:
$ sudo gedit /etc/security/limits.conf
// 1> 文件末尾加上這個(gè)在末尾:
* - nofile 65535
// 2> 創(chuàng)建/etc/systemd/system.conf.d/limits.conf, 并增加內(nèi)容
sudo mkdir /etc/systemd/system.conf.d
sudo touch /etc/systemd/system.conf.d/limits.conf
sudo vim /etc/systemd/system.conf.d/limits.conf
這放到這個(gè)文件去:
[Manager]
DefaultLimitNOFILE=65535
// 3> 最后
systemctl daemon-reexec
然后重啟電腦.
最后 隨便弄一個(gè)進(jìn)程 cat /proc/[pid]/limits 可以看到到"Max open files"變?yōu)?65535
$ cat /proc/3212/limits
