Posted 2021-01-24 lixinliang

安装mysql，安装前准备
如果mysql用户不存在，那么添加mysql用户

groupadd mysql
useradd -g mysql mysql

mysql编译安装
tar -zxvf mysql-5.1.73.tar.gz
cd mysql-5.1.73

yum install ncurses ncurses-devel
./configure  ‘--prefix=/usr/local/mysql‘ ‘--without-debug‘ ‘--with-charset=utf8‘ ‘--with-extra-charsets=all‘ ‘--enable-assembler‘ ‘--with-pthread‘ ‘--enable-thread-safe-client‘ ‘--with-mysqld-ldflags=-all-static‘ ‘--with-client-ldflags=-all-static‘ ‘--with-big-tables‘ ‘--with-readline‘ ‘--with-ssl‘ ‘--with-embedded-server‘ ‘--enable-local-infile‘ ‘--with-plugins=innobase‘

make
make install

到此mysql就安装到了/usr/local/mysql路径下，下面开始mysql的配置工作
安装mysql选项文件

cp support-files/my-medium.cnf /etc/my.cnf
cp -r support-files/mysql.server /etc/init.d/mysqld 
/sbin/chkconfig --del mysqld
/sbin/chkconfig --add mysqld

配置权限表
chown -R mysql:mysql /usr/local/mysql
/usr/local/mysql/bin/mysql_install_db --user=mysql


启动mysql
给/etc/init.d/mysql 执行权限，然后运行
chmod a+wrx /etc/init.d/mysql
/etc/init.d/mysqld start

mysql初始化配置：
包括密码设置等
export PATH=/usr/local/mysql/bin:$PATH
/usr/local/mysql/bin/mysql_secure_installation
　
在弹出的对话框中要求输入密码：
Enter current password for root (enter for none):
默认打回车，然后重新设置root密码:

Set root password? [Y/n] y

Disallow root login remotely? [Y/n] n

Remove test database and access to it? [Y/n] n

Reload privilege tables now? [Y/n] y


至此，Mysql运行成功
