1、修改语言

  阿里云的ECS默认语言是:en_US.UTF-8,需要改成zh_CN.UTF-8

  修改方法:vim /etc/locale.conf,然后重启。

  查看方法:echo $LANG

2、安装ab(ApacheBench)

[root@iZ23n2t9gynZ ~]# yum install httpd-tools

完毕!

  启动mariadb

[root@iZ23n2t9gynZ ~]# systemctl start mariadb

  开机自动启动

[root@iZ23n2t9gynZ ~]# systemctl enable mariadb
ln -s '/usr/lib/systemd/system/mariadb.service' '/etc/systemd/system/multi-user.target.wants/mariadb.service'

  设置root密码

[root@iZ23n2t9gynZ ~]# mysql_secure_installation
/usr/bin/mysql_secure_installation:行379: find_mysql_client: 未找到命令

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current
password for the root user.  If you've just installed MariaDB, and
you haven't 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):
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] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
 ... Success!

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
 ... 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
 ... 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
 - 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
 ... Success!

Cleaning up...

All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!

4、安装redis

yum install -y tcl

wget http://download.redis.io/redis-stable.tar.gz

tar xvzf redis-stable.tar.gz

cd redis-stable

make

 cd src

 make test

  配置redis

cd /root/redis-stable

cp redis.conf /usr/local/bin

cd src

cp redis-server /usr/local/bin

cp redis-cli /usr/local/bin

  配置redis.conf(vim /usr/local/bin/redis.conf)

daemonize yes

port 26125

bind 127.0.0.1

# save 900 1

# save 300 10

# save 60 10000

maxclients 60000

maxmemory 500mb

  启动与客户端连接
