4、linux 上安装mysql

1.基本信息

版本	5.5.39
安装机器	172.24.5.173
账号	root
源路径	/opt/software/mysql_5.5.39_product6.5_new.tar.gz
目标路径	/usr/local/mysql
依赖关系	无

2.安装过程

1).登陆172.24.5.173，切换用户名root，并进入软件包所在目录：

[root@bgs-5p173-wangwenting opt]# exit

[root@bgs-5p173-wangwenting opt]# cd /opt/software

2).配置mysql用户(密码也设置为mysql)：

[root@bgs-5p173-wangwenting software]# groupadd mysql

[root@bgs-5p173-wangwenting software]# useradd -r -g mysql mysql

3).将mysql-5.5.39.tar.gz通过tar -xf命令解压缩至目的安装目录,,并设置软连接，配置目录归属为mysql账户、mysql群。如

[root@bgs-5p173-wangwenting software]# tar -zxvf mysql-${version}.tar.gz  -C  /usr/local

[root@bgs-5p173-wangwenting software]# chown -R mysql:mysql /usr/local/mysql-${version}

[root@bgs-5p173-wangwenting software]# ln -s /usr/local/mysql-${version}/   /usr/local/mysql

[root@bgs-5p173-wangwenting software]# cd /usr/local

[root@bgs-5p173-wangwenting software]# chown -R mysql:mysql mysql*

[root@bgs-5p173-wangwenting software]# ln -s /usr/local/mysql/lib/libmysqlclient.so.18.0.0 /usr/lib64/libmysqlclient.so.18(防止出现找不到libmysqlclient.so.18的错误)

4).初始化mysql：

[root@bgs-5p173-wangwenting software]# cd  /usr/local/mysql

[root@bgs-5p173-wangwenting software]# scripts/mysql_install_db --user=mysql

[root@bgs-5p173-wangwenting software]# cp support-files/my-medium.cnf /etc/my.cnf

[root@bgs-5p173-wangwenting software]# cp support-files/mysql.server  /etc/init.d/mysql.server

5).启动mysql服务:

[root@bgs-5p173-wangwenting software]# /usr/local/mysql/support-files/mysql.server start

若出现Starting MySQL.. SUCCESS!结果代表启动成功。

6).在172.24.5.173上启动Mysql,进入mysql,修改密码以及权限：

# mysql -u root -p

mysql> set password = password("1234");

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '1234';

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@baseline01 IDENTIFIED BY '1234';

mysql>flush privileges;

进入mysql，且密码修改成功，则表示mysql安装和启动成功。

[root@bgs-5p173-wangwenting software]# mysql -u root -p

mysql> set password = password("1234");

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '1234';

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@bgs-5p173-wangwenting IDENTIFIED BY '1234';

mysql>flush privileges;

进入mysql，且密码修改成功，则表示mysql安装和启动成功。
