一.关闭防火墙和SElinux:
systemctl stop firewalld.service
setenforce 0
二.准备环境: 两台虚拟机安装mysql IP:192.168.43.176 IP2:192.168.43.213
三.下载解压mysql:
unzip AliSQL-AliSQL-5.6.32-9.zip
下载依赖包:
yum -y install cmake bison git ncurses-devel gcc gcc-c++
添加用户:
groupadd mysql
useradd -g mysql mysql
下载并解压perl:
wget http://repo.openfusion.net/centos7-x86_64//perl-Data-Dumper-2.154-1.of.el7.x86_64.rpm
rpm -ivh http://repo.openfusion.net/centos7-x86_64//perl-Data-Dumper-2.154-1.of.el7.x86_64.rpm
编译安装
cmake -DCMAKE_INSTALL_PREFIX=/data/server/mysql -DMYSQL_UNIX_ADDR=/data/server/mysql/mysql.sock -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_ARCHIVE_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DMYSQL_DATADIR=/data/server/mysql/data -DMYSQL_TCP_PORT=3306 -DMYSQL_USER=mysql -DENABLE_DOWNLOADS=1
make && make install
修改目录主权限:
chown -R mysql:mysql /data/server/mysql
复制文件给权限:
cd /data/server/mysql
cp support-files/my-default.cnf ./my.cnf
chown -R mysql:mysql my.cnf
配置文件:
vim my.cnf
basedir = /data/server/mysql
datadir = /data/server/mysql/data
socket = /data/server/mysql/mysql.sock
log-error = /dat/server/mysql/data/error.log
pid-file = /data/server/mysql/data/mysql.pid
user = mysql
tmpdir = /tmp
数据库初始化:
scripts/mysql_install_db --defaults-file=./my.cnf --user=mysql
进到support-files中启动数据库:
./mysql.server start
报错PID解决办法
rm -rf /etc/my.cnf
cd /data/server/mysql
rm -rf my.cof
cd data
rm -rf *
cd /data/server/mysql/
scripts/mysql_install_db --defaults-file=./my.cnf --user=mysql
cd support-files
./mysql.server start
进入mysql下的bin目录中,重新启动数据库
cd /data/server/mysql/bin
./mysql -uroot -p
MYSQL 启动完成。
NTP时间服务同步器 准备两台虚拟机 服务端IP:192.168.43.213 客户端IP:192.168.43.176 服务端配置 安装ntp服务
yum install ntp ntpdate -y
修改ntp.conf配置文件
vim /etc/ntp.conf
启动NTP服务
service ntpd start
为了使服务可以在系统引导的时候自动启动,执行
service ntpd startchkconfig ntpd on
检查时间服务器是否正确同步
ntpq -p
客户端配置 关闭防火墙:
systemctl stop firewalld
setenforce 0
客户端安装ntp服务
yum install ntp ntpdate -y
配置ntp.conf文件
vim /etc/ntp.conf
手动同步时间
ntpdate 192.168.124.133
NTP时间同步实现
主从复制 master主库配置
vim /mysql/my.cnf
[mysqld] server-id=1 log-bin=mysql-bin
重启MySQL:cd /data/server/mysql/support-files
./mysql.server restart
新建用于主从同步的用户hong,允许登录的从库是'192.168.43.176'
create user 'hong'@'192.168.43.176' identified by '123';
给从库账号授权,说明给hong从库复制的权限,在192.168.43.176机器上复制
grant replication slave on *.* to 'hong'@'192.168.43.176';
检查主库创建的复制账号
select user,host from mysql.user;
检查授权账号的权限
show grants for hong@'192.168.43.176';
检查主库的状态:
show master status;
slave从库配置 设置server-id值并关闭binlog功能参数 修改Slave的/etc/my.cnf,写入
vim /etc/my.cnf
[mysqld]
server-id=3
重启数据库
cd /data/server/mysql/support-files
./mysql.server restart
检查Slava从数据库的各项参数
show variables like 'log_bin';
show variables like 'server_id';
配置复制的参数,Slave从库连接Master主库的配置
change master to master_host='192.168.43.213',(主库的ip)
master_user='hong',(主库的用户名)
master_password=123',(主库用户的密码)
master_log_file='mysql-bin.000001',(主库的配置参数)
master_log_pos=265;(主库的状态值)
启动从库的同步开关,测试主从复制的情况
start slave;
查看复制状态
show slave status\G;
