CentOS6.8 x86_64bit源碼安裝MySQL-5.5.47

mysql-5.5.47安裝

1.提前下載源碼包或進入服務器中上傳源碼包并解壓出來
cd /home/rich/tools
rz -y "mysql-5.5.47-linux2.6-x86_64.tar.gz"
tar xf mysql-5.5.47-linux2.6-x86_64.tar.gz

2.創(chuàng)建mysql數(shù)據(jù)庫的管理用戶并檢查
useradd -s /sbin/nologin mysql -M
id mysql

3.將解壓出來的源碼包移動或復制到到便于自身管理的目錄下并創(chuàng)建軟件鏈接
mv mysql-5.5.57-linux-glibc2.12-i686 /application/mysql-5.5.57
ln -s /application/mysql-5.5.57/ /application/mysql

4.授權用戶mysql管理mysql的目錄
cd /application/mysql
chown -R mysql.mysql /application/mysql/

5.進入mysql目錄下開始初始化數(shù)據(jù)庫
./scripts/mysql_install_db --basedir=/application/mysql/ --datadir=/application/mysql/data/ --user=mysql

6.更忙啟動腳本文件的默認啟動目錄
cd /application/mysql/bin/
sed -i 's#/usr/local/#/application#g' mysqld_safe

7.復制mysql配置文件my.cnf到服務器的配置目錄下
cd /application/mysql
\cp support-files/my-small.cnf /etc/my.cnf

8.由于環(huán)境變量的原因直接在命令行輸入mysql是無法啟動mysql數(shù)據(jù)庫，所以要指定mysql的啟動目錄文件到服務器的環(huán)境變量中
vi /etc/profile //編輯開機自啟動的配置文件
PATH="/application/mysql/bin:$PATH" >> /etc/profile //添加mysql的啟動目錄文件到環(huán)境變量中
. /etc/profile //命令行執(zhí)行生效

9.修改啟動腳本中mysql自定的安裝目錄
cd /application/mysql
sed -i 's#/usr/local#/application/#g' support-files/mysql.server

10.復制啟動腳本到服務器的啟動腳本目錄下并改名為mysqld
cp support-files/mysql.server /etc/init.d/mysqld
chmod +x /etc/init.d/mysqld //增加mysqld的可執(zhí)行權限

11.啟動與停止mysql數(shù)據(jù)庫
/etc/init.d/mysqld start
/etc/init.d/mysqld stop

12.檢查mysql是否成功啟動
lsof -i :3306 //mysql的默認端口3306

13.添加mysqld到開機自啟動
chkconfig --add mysqld

14.給mysql數(shù)據(jù)創(chuàng)建登陸密碼并使用密碼登陸
mysqladmin password 123456
mysql -uroot -p'123456'
