回车 n y y y yNOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDBSERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!In order to log into MariaDB to secure it, well need the current
password for the root user. If youve just installed MariaDB, and
you havent set the root password yet, the password will be blank,
so you should just press enter here.Enter current password for root (enter for none): # 输入当前root用户密码当前密码为空 ---- 回车即可
OK, successfully used password, moving on...Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.Set root password? [Y/n] n # 是否给root用户设置密码... skipping.By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.Remove anonymous users? [Y/n] y # 是否删除空用户... Success!Normally, root should only be allowed to connect from localhost. This
ensures that someone cannot guess at the root password from the network.Disallow root login remotely? [Y/n] y # 是否禁止root远程登陆... Success!By default, MariaDB comes with a database named test that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.Remove test database and access to it? [Y/n] y # 是否删除test测试库 - Dropping test database...... Success!- Removing privileges on test database...... Success!Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.Reload privilege tables now? [Y/n] y # 是否刷新数据库... Success!Cleaning up...All done! If youve completed all of the above steps, your MariaDB
installation should now be secure.

虚拟内存物理内存swap
1、进程需要的虚拟内存大小包括进程使用的库、代码、数据等
2、假如进程申请100m的内存但实际只使用了10m那么它会增长100m而不是实际的使用量
RES #常驻内存
1、进程当前使用的内存大小但不包括swap out
2、包含其他进程的共享
3、如果申请100m的内存实际使用10m它只增长10m与VIRT相反
4、关于库占用内存的情况它只统计加载的库文件所占内存大小
SHR #共享内存
1、除了自身进程的共享内存也包括其他进程的共享内存
2、虽然进程只使用了几个共享库的函数但它包含了整个共享库的大小
3、计算某个进程所占的物理内存大小公式RES – SHR
4、swap out后它将会降下来常见的Linux系统监控命令 - SSgeek - 博客园www.cnblogs.com
