1.尝试安装平台软件rpc远程调用模块，解决lib库不全和配置文件地址不对的问题，测试rpc程序运行是否正常。
2.尝试安装平台软件monitor模块，解决lib库不全和配置文件地址不对的问题，测试monitor模块运行是否正常。
change master to
master_host='192.168.3.111',
master_log_pos=3266,
master_log_file='master-bin.000001',
master_password='SlaveAdmin',
master_user='data_cp';
主从复制实例：
ubuntu1804 mysql主配置文件的目录：/etc/mysql/mysql.conf.d/
主配置文件：/etc/mysql/mysql.conf.d/mysqld.cnf
一：主mysql服务器的操作如下：
vim /etc/mysql/mysql.conf.d/mysqld.cnf
#[mysqld]
#pid-file = /var/run/mysqld/mysqld.pid
#socket = /var/run/mysqld/mysqld.sock
#datadir = /var/lib/mysql
#log-error = /var/log/mysql/error.log
#bind-address = 0.0.0.0
log-bin=master-bin #如果版本是5.7，则添加此四行
server-id=201
validate_password_length=6
validate_password_policy=0
#############
如果是8.0版本，添加的是一下四行：
log-bin=master-bin #添加此四行
server-id=201
validate_password.length=6
validate_password.policy=0
[root@gitlab ~]# mysql -V
mysql Ver 8.0.33 for Linux on x86_64 (MySQL Community Server - GPL)
service mysql restart
主添加登陆账号及主从复制的权限
create user sync@'%' identified by '123456';
grant replication slave on *.* to sync@'%' ;
show master status

二： 从mysql服务器的配置如下：
vim /etc/mysql/mysql.conf.d/mysqld.cnf
server-id=111
service mysql restart
