mysql 5.7如何進(jìn)行二進(jìn)制普通安裝

這期內(nèi)容當(dāng)中小編將會(huì)給大家?guī)碛嘘P(guān)mysql 5.7如何進(jìn)行二進(jìn)制普通安裝，文章內(nèi)容豐富且以專業(yè)的角度為大家分析和敘述，閱讀完這篇文章希望大家可以有所收獲。

1 官網(wǎng)下載mysql-5.7.29-linux-glibc2.12-x86_64.tar.gz
2 可以先檢查系統(tǒng)中的Mysql或mariadb，如果存在將其卸載
[root@bogon ~]# rpm -qa |grep mysql
php-mysql-5.4.16-46.1.el7_7.x86_64
[root@bogon ~]# rpm -qa |grep mariadb
mariadb-libs-5.5.64-1.el7.x86_64
mariadb-server-5.5.64-1.el7.x86_64
mariadb-5.5.64-1.el7.x86_64
[root@bogon ~]# yum -y remove php-mysql-5.4.16-46.1.el7_7.x86_64

Package          Arch          Version                   Repository       Size

3 useradd -M -s /sbin/nologin -r mysql　　//-M不創(chuàng)建主目錄，-s /sbin/nologin不允許登錄，-r創(chuàng)建的是系統(tǒng)用戶
4  tar zxf mysql-5.7.26-linux-glibc2.12-x86_64.tar.gz -C /usr/local/　　//解壓
5  cd /usr/local/
mv mysql-5.7.26-linux-glibc2.12-x86_64/ mysql
cd mysql
mkdir data　　//創(chuàng)建數(shù)據(jù)目錄
chown -R mysql.mysql /usr/local/mysql/
bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

    //顯示root@localhost第一次登錄的隨機(jī)密碼 注意這里的密碼
    這個(gè)密碼文件
    grep "temporary password" /var/log/mysqld.log

6 [root@bogon mysql]# vi /etc/my.cnf

[mysqld]
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
port=3306
socket=/usr/local/mysql/mysql.sock
character-set-server=utf8
log-error=/var/log/mysqld.log
pid-file=/tmp/mysqld.pid
[mysql]
socket=/usr/local/mysql/mysql.sock
[client]

[root@bogon mysql]# vi /etc/profile.d/mysql.sh
export PATH=/usr/local/mysql/bin:$PATH
[root@bogon mysql]# source /etc/profile.d/mysql.sh
8 cp support-files/mysql.server /etc/init.d/mysqld
vim /etc/init.d/mysqld
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
chmod +x /etc/init.d/mysqld
9 [root@bogon mysql]# /etc/init.d/mysqld stop
Shutting down MySQL.. SUCCESS!
[root@bogon mysql]#
mysql
mysql -uroot -p'e>;Yl?WVp7Na'
由于我剛走完上面這些步驟，此時(shí)計(jì)算機(jī)遠(yuǎn)程突然不能操作，終端丟失了，密碼自然也不見了，于是我就刪kong空var/log/mysqld.log了日志文件進(jìn)行了安全模式的進(jìn)入
cd /usr/local/mysql/bin  
./mysqld_safe --skip-grant-tables & 這個(gè)模式下，MySQL 登錄后
在此執(zhí)行第五步的初始化，找了密碼，
grep "temporary password" /var/log/mysqld.log
在重新啟動(dòng)MySQL，進(jìn)入正常的模式后進(jìn)行密碼的更改。

mysql> set password for root@localhost=password('123456');
mysql>  show variables like 'validate_password%';　查看密碼是否復(fù)雜策略
Empty set (0.00 sec)

mysql> set password=password('1234567');
Query OK, 0 rows affected, 1 warning (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

基于二進(jìn)制的主從復(fù)制
master : /etc/my.cnf 添加：
server-id=1
log-bin=mysql-bin

show variables like 'log_bin';
show master status;
CREATE USER 'repl'@'%.mydomain.com' IDENTIFIED BY 'slavepass';
GRANT REPLICATION SLAVE ON . TO 'repl'@'%.mydomain.com';

slave:
vim /etc/my.cnf 添加如下
server-id = 2

slop slave;

change master to
-> > master_host='192.168.137.2',
->  master_user='repl',
->  master_password='slavepass',
->  master_password='mysql-bin.0000002',
->  master_log_pos=319;
start slave;
show slave status;
看io/sql 線程是否YES, 如果狀態(tài)不對(duì)，就看錯(cuò)誤日志
