echo "PATH=$PATH:/data/opt/percona-server-mongodb-3.4.6-1.7">>/etc/profile
source /etc/profile

创建mongodb配置文件

cat /etc/mongod.conf

storage:

内核优化

echo never > /sys/kernel/mm/redhat_transparent_hugepage/defrag;
echo never > /sys/kernel/mm/redhat_transparent_hugepage/enabled;
echo never > /sys/kernel/mm/transparent_hugepage/enabled;
echo never > /sys/kernel/mm/transparent_hugepage/defrag;
建议写到 /etc/rc.local 中，重启后也可生效
vim /etc/rc.local
echo never > /sys/kernel/mm/redhat_transparent_hugepage/defrag
echo never > /sys/kernel/mm/redhat_transparent_hugepage/enabled
echo never > /sys/kernel/mm/transparent_hugepage/enabled
echo never > /sys/kernel/mm/transparent_hugepage/defrag

启动mongodb

mongod --config /etc/mongod.conf

初始化认证脚本

percona-server-mongodb-enable-auth.sh
