Install MongoDB on RedHat 8

安裝mongo

下載mongoDB RPM

https://repo.mongodb.org/yum/redhat/

https://repo.mongodb.org/yum/redhat/8/mongodb-org/4.2/x86_64/RPMS/

需先安裝python

sudo dnf install python

安裝mongodb rpm

sudo rpm -ivh mongodb-org-server-4.2.8-1.el8.x86_64.rpm mongodb-org-mongos-4.2.8-1.el8.x86_64.rpm mongodb-org-shell-4.2.8-1.el8.x86_64.rpm mongodb-org-tools-4.2.8-1.el8.x86_64.rpm mongodb-org-4.2.8-1.el8.x86_64.rpm

SELinux is preventing /usr/bin/mongod from read access on the file memory.limit_in_bytes 解決方式

  1. 參考https://docs.mongodb.com/manual/tutorial/install-mongodb-on-red-hat/
  2. sudo yum install checkpolicy
  3. Create a custom policy file mongodb_cgroup_memory.te:
cat > mongodb_cgroup_memory.te <<EOF
module mongodb_cgroup_memory 1.0;

require {
    type cgroup_t;
    type mongod_t;
    class dir search;
    class file { getattr open read };
}

#============= mongod_t ==============
allow mongod_t cgroup_t:dir search;
allow mongod_t cgroup_t:file { getattr open read };
EOF
  1. Once created, compile and load the custom policy module by running these three commands:
checkmodule -M -m -o mongodb_cgroup_memory.mod mongodb_cgroup_memory.te
semodule_package -o mongodb_cgroup_memory.pp -m mongodb_cgroup_memory.mod
sudo semodule -i mongodb_cgroup_memory.pp
  1. sudo systemctl retart mongod

 Failed to unlink socket file /tmp/mongodb-27017.sock errno:1 Operation not permitted解決方式

rm /tmp/mongodb-27017.sock
sudo systemctl retart mongod
