Linux環境下安裝MySQL(解壓方式)

1.將安裝包放在服務器上：
mysql-5.6.37-linux-glibc2.12-x86_64.tar.gz

2.將安裝包解壓：
tar -zxvf mysql-5.6.37-linux-glibc2.12-x86_64.tar.gz

3.將解壓的文件復制到指定的文件夾下：
mkdir /home/mysql/
mv ./mysql-5.6.33-linux-glibc2.12-x86_64/* /home/mysql/

4.添加用戶組
groupadd mysql
添加用戶mysql 到用戶組mysql
useradd -g mysql mysql

5.安裝
cd /usr/local/mysql/
mkdir ./data/mysql
chown -R mysql:mysql ./
./scripts/mysql_install_db --user=mysql --datadir=/usr/local/mysql/data/mysql
cp support-files/mysql.server /etc/init.d/mysqld
chmod 755 /etc/init.d/mysqld
cp support-files/my-default.cnf /etc/my.cnf

6.修改啟動腳本
vi /etc/init.d/mysqld
修改項：
basedir=/usr/local/mysql/
datadir=/usr/local/mysql/data/mysql

7.啟動服務
service mysqld start

8.測試連接
./mysql/bin/mysql -uroot

9.加入環境變量，編輯 /etc/profile，這樣可以在任何地方用mysql命令了
export PATH=$PATH:/usr/local/mysql//bin
source /etc/profile

10.其他問題
修改mysql的連接用戶名和密碼
更改 ‘mysql’數據庫‘user’表‘host’項，從‘localhost’改成‘%’。

-bash: ./scripts/mysql_install_db: /usr/bin/perl: bad interpreter: 沒有那個文件或目錄
解決： yum -y install perl perl-devel

Installing MySQL system tables..../bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory
解決：yum -y install libaio-deve

配置環境變量
vi + /etc/profile
export PATH=....:/usr/local/mysql/bin
