标签：识别 specified docker comm centos7 现在 compose rar serve
刚刚用docker-compose部署elk的时候，没有起来，查看日志的时候，发现在数据卷挂载的时候，报错权限不足。
由于日志不在了，这里就直接贴出解决办法。
问题原因及解决办法
原因是CentOS7中的安全模块selinux把权限禁掉了，至少有以下三种方式解决挂载的目录没有权限的问题：
1.在运行容器的时候，给容器加特权，及加上 --privileged=true 参数：
docker run -i -t -v /soft:/soft --privileged=true 686672a1d0cc /bin/bash
注：这种适合docker run
2.临时关闭selinux：
setenforce 0
用这种解决了问题。
3.添加selinux规则，改变要挂载的目录的安全性文本
# 更改安全性文本的格式如下
chcon [-R] [-t type] [-u user] [-r role] 文件或者目录 选顷不参数： -R ：连同该目录下癿次目录也同时修改； -t ：后面接安全性本文的类型字段！例如 httpd_sys_content_t ； -u ：后面接身份识别，例如 system_u； -r ：后面街觇色，例如 system_r [root@localhost Desktop]# chcon --help Usage: chcon [OPTION]... CONTEXT FILE... or: chcon [OPTION]... [-u USER] [-r ROLE] [-l RANGE] [-t TYPE] FILE... or: chcon [OPTION]... --reference=RFILE FILE... Change the SELinux security context of each FILE to CONTEXT. With --reference, change the security context of each FILE to that of RFILE. Mandatory arguments to long options are mandatory for short options too. --dereference affect the referent of each symbolic link (this is the default), rather than the symbolic link itself -h, --no-dereference affect symbolic links instead of any referenced file -u, --user=USER set user USER in the target security context -r, --role=ROLE set role ROLE in the target security context -t, --type=TYPE set type TYPE in the target security context -l, --range=RANGE set range RANGE in the target security context --no-preserve-root do not treat ‘/‘ specially (the default) --preserve-root fail to operate recursively on ‘/‘ --reference=RFILE use RFILE‘s security context rather than specifying a CONTEXT value -R, --recursive operate on files and directories recursively -v, --verbose output a diagnostic for every file processed The following options modify how a hierarchy is traversed when the -R option is also specified. If more than one is specified, only the final one takes effect. -H if a command line argument is a symbolic link to a directory, traverse it -L traverse every symbolic link to a directory encountered -P do not traverse any symbolic links (default) --help display this help and exit --version output version information and exit GNU coreutils online help: <http://www.gnu.org/software/coreutils/> For complete documentation, run: info coreutils ‘chcon invocation‘
在主机中修改/soft目录的安全性文档
[root@localhost Desktop]# chcon -Rt svirt_sandbox_file_t /soft [root@ba471da26d07 soft]# ll total 384264 -rw-r--r--. 1 root root 212046774 Aug 8 10:01 hadoop-2.7.2.tar.gz -rw-r--r--. 1 root root 181435897 Aug 8 09:23 jdk-8u102-linux-x64.tar.gz 在docker中就可以正常访问该目录下的相关资源了。
