安裝mysql5.7和mysql5.6詳

centos7和centos6.5環境rpm方式安裝mysql5.7和mysql5.6詳解

centos環境安裝mysql5.7

其實不建議安裝mysql5.7 語法和配置可能和以前的版本區別較大，多坑，慎入

1.yum方式安裝(不推薦)

a.安裝mysql5.7 yum源

centos6:

wget dev.mysql.com/get/mysql-community-release-el6-5.noarch.rpm
yum localinstall mysql-community-release-el6-5.noarch.rpm

centos7:

wget dev.mysql.com/get/mysql57-community-release-el7-7.noarch.rpm

yum localinstall mysql57-community-release-el7-7.noarch.rpm

yum方式安裝：
yum install mysql-community-server

2.rpm方式安裝(推薦)
因yum源是在國外下載速度非常慢，建議直接下載後通過本地安裝

centos6:
mysql-community-client-5.7.15-1.el6.x86_64.rpm
mysql-community-common-5.7.15-1.el6.x86_64.rpm
mysql-community-libs-5.7.15-1.el6.x86_64.rpm
mysql-community-server-5.7.15-1.el6.x86_64.rpm

centos7:
mysql-community-client-5.7.15-1.el7.x86_64.rpm
mysql-community-common-5.7.15-1.el7.x86_64.rpm
mysql-community-libs-5.7.15-1.el7.x86_64.rpm
mysql-community-server-5.7.15-1.el7.x86_64.rpm

yum localinstall -y mysql-community*.rpm

報錯：

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

解決辦法：
rpm -e --nodeps mysql-libs-5.1.71-1.el6.x86_64

1）默認 root 密碼為空，其實不為空，使用 mysql -u root -p 進行登錄失敗
2)mysql_secure_installation這個初始化也不行

直接編輯mysql配置文件
vim /etc/my.cnf
加入
skip-grant-tables
註意：要加在[mysqld]的位置

重啟數據庫

#進入 mysql控制臺

# mysql

可能的報錯：

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (111)

解決辦法：加上-h127.0.0.1
[root@node2 bin]# mysql -h127.0.0.1 -uroot -p

# 修改密碼

刪掉skip-grant-tables，再次重啟即可

添加用戶時，報錯，是因為密碼策略的問題，我們只是測試，密碼不需要那麽復雜

mysql> grant all privileges on test.* to jack@'%' identified by "test";

ERROR 1819 (HY000): Your password does not satisfy the current policy requirements

修改密碼策略即可
mysql> set global validate_password_policy=0;

centos6.5環境安裝mysql5.6

操作系統：centos6.5 x86_64

1.檢查下linux是不是已經安裝了mysql
rpm -qa | grep -i mysql


#如果安裝了先卸載舊的版本
rpm -e --nodeps mysql...

rpm -e --nodeps mysql-libs-5.1.73-5.el6_6.x86_64


2.下載需要的安裝包，下載地址：
http://dev.mysql.com/downloads/mysql/5.6.html#downloads

MySQL-client-5.6.34-1.el6.x86_64.rpm
MySQL-devel-5.6.34-1.el6.x86_64.rpm
MySQL-server-5.6.34-1.el6.x86_64.rpm

全部安裝

yum install numactl -y
rpm -ivh MySQL-*.rpm


3.修改配置文件位置並做相關設置

cp /usr/share/mysql/my-default.cnf /etc/my.cnf

默認的數據庫放在/var/lib/mysql目錄下，我們需要將數據庫放在/data/yunva/mysqldata 目錄下，主要是/var/lib是系統根目錄，數據庫文件較大的時候系統磁盤空間會不夠

vim /etc/my.cnf

innodb_file_per_table = 1
datadir = /data/yunva/mysql/mysqldata
log-bin=/data/yunva/mysql/binlogs/mysql-bin

修改目錄權限

chmod 755 /data/yunva/mysql/

mkdir -p /data/yunva/mysql/mysqldata

mkdir /data/yunva/mysql/binlogs/

# 註意必須給mysqldata和mysqlbin目錄賦權給mysql否則無法啟動
chown -R mysql.mysql /data/yunva/mysql


刪除匿名用戶
mysql> delete from user where user='' and host='localhost' or host='monitor01';

添加root密碼
mysql> update user set password=PASSWORD('pass');
Query OK, 3 rows affected (0.00 sec)
Rows matched: 3 Changed: 3 Warnings: 0

mysql> flush privileges;

如果之前的版本有安裝，需要重置root密碼，可以在my.cnf的mysqld步伐加入，重啟mysql，不輸入密碼即可進數據庫
skip-grant-tables

密碼默認位置：

# cat /root/.mysql_secret

4.初始化MySQL及設置密碼

/usr/bin/mysql_install_db
service mysql start

可能碰到的錯誤：
明明已經修改了mysql.user表中的root密碼，執行命令報錯：

mysql> show databases;
ERROR 1820 (HY000): You must SET PASSWORD before executing this statement
mysql> use mysql;
ERROR 1820 (HY000): You must SET PASSWORD before executing this statement

解決辦法：
mysql> SET PASSWORD = PASSWORD('123');
Query OK, 0 rows affected (0.00 sec)

報錯：

# rpm -ivh MySQL-server-5.6.34-1.el6.x86_64.rpm
warning: MySQL-server-5.6.34-1.el6.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY
error: Failed dependencies:
libnuma.so.1()(64bit) is needed by MySQL-server-5.6.34-1.el6.x86_64
libnuma.so.1(libnuma_1.1)(64bit) is needed by MySQL-server-5.6.34-1.el6.x86_64
libnuma.so.1(libnuma_1.2)(64bit) is needed by MySQL-server-5.6.34-1.el6.x86_64

解決辦法：
[root@monitor01 software]# yum install numactl -y

報錯：

# service mysql start
Starting MySQL. ERROR! The server quit without updating PID file (/data/yunva/mysqldata/10-10-50-133.pid).

是因為上級目錄/data/yunva對mysql沒有權限

解決辦法：chown -R mysql.mysq /data/yunva
