MongoDB的3.2.9無法啓動爲在CentOS

服務，我想開始的mongod作爲在CentOS服務：MongoDB的3.2.9無法啓動爲在CentOS

mongod --version 
db version v3.2.9 
git version: 22ec9e93b40c85fc7cae7d56e7d6a02fd811088c 
OpenSSL version: OpenSSL 1.0.1e-fips 11 Feb 2013 
allocator: tcmalloc 
modules: none 
build environment: 
    distmod: rhel70 
    distarch: x86_64 
    target_arch: x86_64 

CentOS Linux release 7.2.1511 (Core)

的/ etc/SELinux的/配置：

# This file controls the state of SELinux on the system. 
# SELINUX= can take one of these three values: 
#  enforcing - SELinux security policy is enforced. 
#  permissive - SELinux prints warnings instead of enforcing. 
#  disabled - No SELinux policy is loaded. 
SELINUX=disabled 
# SELINUXTYPE= can take one of three two values: 
#  targeted - Targeted processes are protected, 
#  minimum - Modification of targeted policy. Only selected processes are protected. 
#  mls - Multi Level Security protection. 
SELINUXTYPE=targeted

的mongod。 CONF：

    destination: file 
    path: "/mnt/log/mongod.log" 
    logAppend: true

服務器開始使用：

sudo mongod -f /etc/mongod.conf

我知道有關於類似的問題，但修復可能會在3.2.7已經可用，除了它是涉及到的場景時SELINUX =強制執行措施開了一個錯誤...

請支持。

最近遇到類似的問題，但在FC26上;在這裏，問題可以追溯到SELINUX，特別是自定義dbPath目錄的權限。

嘗試很多事情之後，我發現下列順序幫助解決我的問題：

MONGODB_DATADIR=/mnt/data 

sudo chown -R mongodb:mongodb $MONGODB_DATADIR 
sudo chmod -R 700 $MONGODB_DATADIR

SELinux的設置：

sudo semanage port -a -t mongod_port_t -p tcp 27017 

sudo semanage fcontext -a -t mongod_var_lib_t ${MONGODB_DATADIR} 
sudo semanage fcontext -a -t mongod_var_lib_t ${MONGODB_DATADIR}/mongod.lock 
sudo restorecon -v ${MONGODB_DATADIR}

你可能還需要添加mongod_log_t到自定義日誌文件的位置，/mnt/log/mongod.log，我沒有在我的最後修改那個。
