普通二進(jìn)制文件安裝mysql5.7.16的步驟

這篇文章主要講解了“普通二進(jìn)制文件安裝5.7.16的步驟”，文中的講解內容簡(jiǎn)單清晰，易于學(xué)習與理解，下面請大家跟著(zhù)小編的思路慢慢深入，一起來(lái)研究和學(xué)習“普通二進(jìn)制文件安裝mysql5.7.16的步驟”吧！

1.安裝環(huán)境：

centos6.5 x64

2.安裝過(guò)程

2.1 準備過(guò)程：

安裝如下rpm：
yum list | grep libaio  #安裝所有包

2.2 實(shí)際安裝步驟：

groupadd mysql
useradd -r -g mysql -s /bin/false mysql
cd /usr/local
tar zxvf ~/mysql-5.7.16-linux-glibc2.5-x86_64.tar.gz
ln -s mysql-5.7.16-linux-glibc2.5-x86_64 mysql
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld # config auto start service,optional
cd /usr/local/mysql
mkdir /usr/local/mysql/mysql-files
chmod 750 mysql-files
chown -R mysql .
chgrp -R mysql .
echo 'export PATH=$PATH:/usr/local/mysql/bin' >> ~/.bash_profile
source ~/.bash_profile
bin/mysqld --initialize --user=mysql # MySQL 5.7.6 and up ,---未生成data目錄
bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data #--ylrK.ea!o3os
bin/mysql_ssl_rsa_setup # MySQL 5.7.6 and up
chown -R root .
chown -R mysql data mysql-files
bin/mysqld_safe --user=mysql & #啟動(dòng)數據庫

3. 報錯解決

#---報錯1如下：mysql自動(dòng)報錯

#---報錯2如下

# 重啟

#---報錯3如下：初始登陸報錯
#----------------------------------------------------
# mysql -uroot -p 
Enter password: 
ERROR 2002 (HY000): Cant connect to local MySQL server through socket '/tmp/mysql.sock' (2)
# 解決方式1
#將配置文件/etc/my.cnf 做如下變更：
socket=/var/lib/mysql/mysql.sock --> socket=/tmp/mysql.sock
#未解決問(wèn)題

# 解決方式2
在解決方式1的基礎上：
停止mysql： kill -9 <>
運行mysqld_safe --skip-grant-tables & 
如果此時(shí)不想被遠程連接：mysqld_safe --skip-grant-tables --skip-networking &
使用mysql連接server：mysql -uroot -p 
更改密碼： update mysql.user set authentication_string=password('123qwe') where user='root' and Host = 'localhost';
*特別提醒注意的一點(diǎn)是，新版的mysql數據庫下的user表中已經(jīng)沒(méi)有Password字段了

而是將加密后的用戶(hù)密碼存儲于authentication_string字段
mysql> flush privileges;
mysql> quit;
修改完畢。重啟
killall -TERM mysqld。 
mysqld_safe &
#解決問(wèn)題
