LNMP源碼編譯安裝之Mysql

此處後補一張集羣架構圖

Mysql 數據庫
是一種關係型數據庫管理軟件，關係型數據庫特點是將數據庫保存在不同的二維表（Excel）中，並且將這些表放入不同的數據庫中，而不是把所有數據統一放在一個大倉庫裏，這樣的設計增加了Mysql的讀取速度，靈活性和可管理性也得到了很大提高。訪問及管理Mysql數據庫的最常用標準化語言爲SQL結構化查詢語言。

Mysql安裝

[root@web01 ~]# useradd -s /sbin/noligin mysql -M
[root@web01 tools]# mv mysql-5.5.49-linux2.6-x86_64 /application/mysql-5.5.49
[root@web01 tools]# cd /application/mysql-5.5.49/
[root@web01 tools]# ln -s /application/mysql-5.5.49/ /application/mysql
[root@web01 mysql]# chown -R mysql.mysql /application/mysql/
[root@web01 mysql]# ./scripts/mysql_install_db --basedir=/application/mysql/ --datadir=/application/mysql/data/ --user=mysql   初始化

修改配置文件

cd /application/mysql/bin
sed -i 's#/usr/local/#/application/#g' mysqld_safe 
sed -i 's#/usr/local/#/application/#g' support-files/mysql.server  
cp support-files/mysql.server /etc/init.d/mysqld  拷貝到啓動腳本
chmod +x /etc/init.d/mysqld 賦予權限
[root@web01 bin]# less mysqld_safe

指定配置文件

[root@web01 mysql]# cp support-files/my-small.cnf /etc/my.cnf 
cp：是否覆蓋"/etc/my.cnf"？ y
