基础优化
# --所有机器

net.ipv4.tcp_tw_reuse=1
net.ipv4.tcp_tw_recycle = 1
net.ipv4.tcp_timestamps = 1
net.ipv4.tcp_fin_timeout = 30
最后生效以上设置：
sysctl -p
# --cache_agent机器额外两条优化
#追加以下参数到/etc/sysctl.conf
net.core.somaxconn = 511
vm.swappiness = 1
最后生效以上设置：
sysctl -p
#--cache/Proxy机器配置以下设置：
echo never > /sys/kernel/mm/transparent_hugepage/enabled
#如果需要重启生效，需要追加命令到/etc/rc.local
echo 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' >> /etc/rc.local
#--所有Cache/Proxy机器
ulimit -SHn 65535
#配置重启生效

#挂载磁盘
#每台服务器新增一块磁盘

中控机操作[第一台服务器]
#中控机服务器安装mariadb
yum install -y mariadb-server
systemctl start mariadb
systemctl enable mariadb
#mariadb初始化[可以不用初始化]：
[root@server1 ~]# mysql_secure_installation
Enter current password for root (enter for none): <–初次运行直接回车
Set root password? [Y/n] <– 是否设置root用户密码，输入y并回车或直接回车
New password: <– 设置root用户的密码
Re-enter new password: <– 再输入一次你设置的密码
Password updated successfully!
… Success!
Remove anonymous users? [Y/n] <– 是否删除匿名用户,生产环境建议删除，所以直接回车
… Success!
Disallow root login remotely? [Y/n] n <–是否禁止root远程登录,根据自己的需求选择Y/n并回车,建议禁止，这里不用禁止
… Success!
Remove test database and access to it? [Y/n] y <– 是否删除test数据库,直接回车
Reload privilege tables now? [Y/n] <– 是否重新加载权限表，直接回车
… Success!
连接数据库：
mysql -uroot -p123456
#创建用户并授权
GRANT ALL PRIVILEGES ON *.* to 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;
FLUSH privileges;
GRANT ALL PRIVILEGES ON *.* TO 'mysql'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;
flush privileges;
#删除空账号密码的条目
use mysql;
delete from user where user='';
delete from user where password='';
select user,host,password from mysql.user;
#测试连接：
其他服务器安装一个mariadb，这里我直接用 node2 服务器测试连接node1的mysql
测试连接
yum install -y mariadb
#测试：
[root@node2 ~]# mysql -umysql -p123456 -h 192.168.3.81

安装 cache服务和proxy
看环境规划中有两台是作为cache服务的
分别是
192.168.3.84
192.168.3.85
需要把安装包传到这两台服务器进行安装：
[可以全部安装 然后界面选择就好，我这里全部安装了，演示只装了2台]
# 192.168.3.84安装cache_agent服务：

上架机器
#proxy 2台 [规划 192.168.3.82，192.168.3.83]
连接到数据库i：
mysql -h192.168.3.81 -umysql -p123456
#首先把所有cacahe都上架完成
cache 4台 [规划 192.168.3.82，192.168.3.83,192.168.3.84,192.168.3.85]
