centos7 打開8080端口

Use this command to find your active zone(s):

firewall-cmd --get-active-zones
It will say either public, dmz, or something else. You should only apply to the zones required.

In the case of dmz try:

firewall-cmd --zone=dmz --add-port=2888/tcp --permanent
Otherwise, substitute dmz for your zone, for example, if your zone is public:

firewall-cmd --zone=public --add-port=2888/tcp --permanent
Then remember to reload the firewall for changes to take effect.

firewall-cmd --reload

centOs防火墻放行Samba
systemctl start firewalld.service
firewall-cmd --permanent --add-service=samba

ftp登錄之后查看不了文件
https://www.0xaa55.com/thread-1149-1-1.html

解決辦法：運(yùn)行 getsebool -a | grep ftpd 判斷查看權(quán)限景殷。
[Bash shell] 純文本查看 復(fù)制代碼
?
1
getsebool -a | grep ftpd
通常會(huì)顯示如下內(nèi)容：
allow_ftpd_anon_write --> off
allow_ftpd_full_access --> off
allow_ftpd_use_cifs --> off
allow_ftpd_use_nfs --> off
ftpd_connect_db --> off
ftpd_use_passive_mode --> off
ftp_home_dir --> off
其中经宏，ftp_home_dir和allow_ftpd_full_access必須為on才行既棺。
運(yùn)行以下命令：

setsebool -P ftp_home_dir 1
setsebool -P allow_ftpd_full_access 1
注意這兩條命令一般需要花上十幾秒鐘才能運(yùn)行完（也許是我的VPS不太好吧）
運(yùn)行完了以后，我們?cè)僦匦禄謴?fù)SELinux進(jìn)入Enforcing模式。

如果不出意外的話俯树，vsFTPd就可以正常上傳下載文件了。

但是如果就此問題還沒解決的話贰盗，可能是FTP訪問的目錄屬性不夠许饿。建議用 chmod -R 777 路徑 將路徑讀寫屬性設(shè)置為777，再嘗試舵盈，通常也能解決問題陋率。

命令行安裝build-tools

./tools/android list sdk --all
./tools/android update sdk -u -a -t 7（上面all列出來的所有選項(xiàng)，需要安裝的編號(hào)）

Jenkins報(bào)ModuleVersionNotFoundException秽晚，但是本地AndroidStudio可以編譯通過瓦糟。

解決：把本地引用aar的包名字改成小寫字母

=============================
Could not find support-compat.aar

解決方法 調(diào)換maven { url 'https://maven.google.com' }和jcenter()
allprojects {
repositories {
maven { url 'https://maven.google.com' }
jcenter()
}
}
