Mysql运维篇（六）部署MHA--一主二从部署

MAH架构图

一、上传MySQL软件

1、同步MySQL软件

$root@mysql01 \~$ # ls -lrt

total 626112

-rw-r--r--. 1 root root 641127384 Jan 30 15:13 mysql-5.7.20-linux-glibc2.12-x86_64.tar.gz

-rw-------. 1 root root 1697 Feb 3 12:09 anaconda-ks.cfg

-rw-r--r--. 1 root root 1907 Feb 3 12:12 initial-setup-ks.cfg

$root@mysql01 \~$ #

$root@mysql01 \~$ # rsync -avl mysql-5.7.20-linux-glibc2.12-x86_64.tar.gz root@mysql02

sending incremental file list

mysql-5.7.20-linux-glibc2.12-x86_64.tar.gz

sent 641,284,023 bytes received 35 bytes 116,597,101.45 bytes/sec

total size is 641,127,384 speedup is 1.00

$root@mysql01 \~$ #

$root@mysql01 \~$ # rsync -avl mysql-5.7.20-linux-glibc2.12-x86_64.tar.gz root@mysql03

sending incremental file list

mysql-5.7.20-linux-glibc2.12-x86_64.tar.gz

sent 641,284,023 bytes received 35 bytes 142,507,568.44 bytes/sec

total size is 641,127,384 speedup is 1.00

$root@mysql01 \~$ #

2、解压mysql-5.7.20-linux-glibc2.12-x86_64.tar.gz

$root@mysql03 \~$ # tar -xvzf mysql-5.7.20-linux-glibc2.12-x86_64.tar.gz

$root@mysql03 \~$ # mv mysql-5.7.20-linux-glibc2.12-x86_64 mysql

$root@mysql03 \~$ # mv mysql /usr/local/mysql/

二、一主二从数据库搭建

1、准备MySQL配置化文件，最对应主机执行

复制代码

主库db01：
cat > /etc/my.cnf <<EOF
[mysqld]
basedir=/usr/local/mysql/
datadir=/data/mysql/data
socket=/tmp/mysql.sock
server_id=1
port=3306
secure-file-priv=/tmp
autocommit=0
log_bin=/data/binlog/mysql-bin
binlog_format=row
gtid-mode=on
enforce-gtid-consistency=true
log-slave-updates=1
[mysql]
prompt=db01 [\\d]>
EOF

slave1(db02)：
cat > /etc/my.cnf <<EOF
[mysqld]
basedir=/usr/local/mysql/
datadir=/data/mysql/data
socket=/tmp/mysql.sock
server_id=2
port=3306
secure-file-priv=/tmp
autocommit=0
log_bin=/data/binlog/mysql-bin
binlog_format=row
gtid-mode=on
enforce-gtid-consistency=true
log-slave-updates=1
[mysql]
prompt=db02 [\\d]>
EOF

slave2(db03)：
cat > /etc/my.cnf <<EOF
[mysqld]
basedir=/usr/local/mysql/
datadir=/data/mysql/data
socket=/tmp/mysql.sock
server_id=3
port=3306
secure-file-priv=/tmp
autocommit=0
log_bin=/data/binlog/mysql-bin
binlog_format=row
gtid-mode=on
enforce-gtid-consistency=true
log-slave-updates=1
[mysql]
prompt=db03 [\\d]>
EOF

2、初始化数据库--ALL

cd /usr/local/mysql/bin

$root@mysql03 \~$ # mysqld --initialize-insecure --user=mysql --basedir=/data/mysql --datadir=/data/mysql/data
