1.两台服务器 192.168.1.217 192.168.1.218
配置mysql数据库
yum -y install cmake bison git ncurses-devel gcc gcc-c++
cmake -DCMAKE_INSTALL_PREFIX=/data/server/mysql -DMYSQL_DATADIR=/data/server/mysql/data -DSYSCONFDIR=/etc -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_MEMORY_STORAGE_ENGINE=1 -DWITH_READLINE=1 -DMYSQL_UNIX_ADDR=/data/server/mysql/mysql.sock -DMYSQL_TCP_PORT=3306 -DENABLED_LOCAL_INFILE=1 -DWITH_PARTITION_STORAGE_ENGINE=1 -DEXTRA_CHARSETS=all -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci
make
make install
2.配置mysql
groupadd mysql
useradd -M -g mysql -s /sbin/nologin mysql
chown -R mysql:mysql /data/sevser/mysql
3.cd /data/server/mysql/scripts
./mysql_install_db --basedir=/data/server/mysql --datadir=/data/server/mysql/data --user=mysql
4.AliSQL修改目录主权限
chown -R mysql:mysql /data/server/mysql
5.cd /data/server/mysql
cp support-files/my-medium.cnf ./etc/my.cnf
chown -R mysql:mysql /etc/my.cnf
6.主机配置文件vim my.cnf
在脚本末尾添加
user = mysql
tmpdir = /tmp
7.设置mysql为系统服务
vim /lib/systemd/system/mysql.service
[Unit]
Description=mysql
After=network.target
[Service]
Type=forking
ExecStart=/data/server/mysql/support-files/mysql.server start
ExecStop=/data/server/mysql/support-files/mysql.server stop
ExecRestart=/data/server/mysql/support-files/mysql.server restart
ExecReload=/data/server/mysql/support-files/mysql.server reload
PrivateTmp=true
[Install]
WantedBy=multi-user.target
8.13.切换到/bin目录
cd /data/server/mysql/bin
./mysql –u root –p
按回车后进入交互界面 密码不用敲 直接按enter回车就行
9.主机定位主库
cd /data/server/mysql/bin
./mysql -u root -p
create user zc@192.168.1.218 identified by ‘123’; 此处也是客户机的IP
grant replication slave on . to zc@192.168.1.218; 此处也是客户机的IP
grant replication slave on . to zc@192.168.1.218;
select user,host from mysql.user;

10.编辑配置文件
vim /etc/my.cnf
关闭binlog功能参数
重启数据库
./mysql -u root -p
