Linux下mysql主从部署——免安装版本（直接压缩包解压）

一、首先下载压缩包（主从两台服务器都下载）

二、部署mysql主

1、解压安装包+配置

tar xf Percona-Server-5.7.30-33-Linux.x86_64.ssl101.tar.gz ##解压安装包
useradd -s /sbin/nologin mysql  ##创建mysql用户
mkdir -p /data/mysql3306/{logs,data,tmp}  ##创建目录
mkdir -p /etc/mysql  #创建目录
ln -s /root/Percona-Server-5.7.30-33-Linux.x86_64.ssl101 /usr/local/mysql5.7  ##创建软连接
chown -R mysql.mysql /data/mysql3306 ##赋权

2、配置my.cnf

mem=$(free -h | awk '/Mem:/{print $2}')
echo $mem | grep --color "\."

if [ $? -eq 0 ]    ##指上一次执行的结果，成功是0，失败是1；此语句判断执行结果是否成功
then
frees=$(echo $mem | awk -F'.' '{print $1}')
else
frees=$(echo $mem | tr -cd '[0-9]')
fi

free=$(echo $frees*0.8 | bc | awk -F'.' '{print $1}')

3、启动mysql

/usr/local/mysql5.7/bin/mysqld --defaults-file=/etc/mysql/my.cnf --initialize --user=mysql
nohup /usr/local/mysql5.7/bin/mysqld_safe --defaults-file=/etc/mysql/my.cnf &> /data/mysql3306/logs/runlog.log &

4、修改mysql中root密码

defaltpass="$(awk '/temporary password is/{print $NF}' /data/mysql3306/logs/mysqld.log)"
HISTCONTROL=ignorespace
  /usr/local/mysql5.7/bin/mysql --connect-expired-password -u root -p"$defaltpass" -S /data/mysql3306/tmp/mysql.sock  -e"set password=password('Zhanghaha123');"
  /usr/local/mysql5.7/bin/mysql -u root -p'Zhanghaha123' -S /data/mysql3306/tmp/mysql.sock  -e"flush privileges;"

5、新建用户+授权

/usr/local/mysql5.7/bin/mysql -u root -p'Zhanghaha123' -S /data/mysql3306/tmp/mysql.sock  -e"create  user dev_eaf@'%' identified by 'test@2022';"

6、新建数据库+赋权

/usr/local/mysql5.7/bin/mysql -u root -p'Zhanghaha123' -S /data/mysql3306/tmp/mysql.sock  -e"create database test;"
    /usr/local/mysql5.7/bin/mysql -u root -p'Zhanghaha123' -S /data/mysql3306/tmp/mysql.sock  -e"grant select ,update,delete,insert  on  .*  to   dev_eaf@'%';"

7、主库中创建从节点用户+授权

下面IP为对应从节点IP

/usr/local/mysql5.7/bin/mysql -u root -p'Zhanghaha123' -S /data/mysql3306/tmp/mysql.sock  -e"create  user repl@'172.30.5.125' identified by 'Repl@2022';"      
  /usr/local/mysql5.7/bin/mysql -u root -p'Zhanghaha123' -S /data/mysql3306/tmp/mysql.sock  -e"grant REPLICATION CLIENT,REPLICATION  SLAVE ,SELECT ON *.*  to   repl@'172.30.5.125';"

8、配置开机自启动

chmod +x /etc/rc.d/rc.local
grep "mysqld_safe" /etc/rc.d/rc.local > /dev/null
echo "nohup /usr/local/mysql5.7/bin/mysqld_safe --defaults-file=/etc/mysql/my.cnf &> /data/mysql3306/logs/runlog.log &" >> /etc/rc.d/rc.local

三、部署从节点

1、解压安装包，配置 （与主节点类似）

tar xf Percona-Server-5.7.30-33-Linux.x86_64.ssl101.tar.gz
useradd -s /sbin/nologin mysql
mkdir -p /data/mysql3306/{logs,data,tmp}
mkdir -p /etc/mysql/
ln -s /root/Percona-Server-5.7.30-33-Linux.x86_64.ssl101 /usr/local/mysql5.7
chown -R mysql.mysql /data/mysql3306

2、配置my.cnf

mem=$(free -h | awk '/Mem:/{print $2}')
echo $mem | grep --color "\."

if [ $? -eq 0 ]
then
frees=$(echo $mem | awk -F'.' '{print $1}')
else
frees=$(echo $mem | tr -cd '[0-9]')
fi

free=$(echo $frees*0.8 | bc | awk -F'.' '{print $1}')

3、启动mysql

/usr/local/mysql5.7/bin/mysqld --defaults-file=/etc/mysql/my.cnf --initialize --user=mysql
nohup /usr/local/mysql5.7/bin/mysqld_safe --defaults-file=/etc/mysql/my.cnf &> /data/mysql3306/logs/runlog.log &

4、修改mysql中root用户密码

defaltpass="$(awk '/temporary password is/{print $NF}' /data/mysql3306/logs/mysqld.log)"
HISTCONTROL=ignorespace
  /usr/local/mysql5.7/bin/mysql --connect-expired-password -u root -p"$defaltpass" -S /data/mysql3306/tmp/mysql.sock  -e"set password=password('Zhanghaha123'); flush privileges;"

5、配置master+启动slave

IP为master对应IP

/usr/local/mysql5.7/bin/mysql -u root -p'Zhanghaha123' -S /data/mysql3306/tmp/mysql.sock  -e"CHANGE MASTER TO MASTER_HOST='173.20.5.155',master_user='repl',master_password='Repl@2022',master_auto_position=1;"
