11.1 LAMP架构介绍
11.2 MySQL、MariaDB介绍
11.3/11.4/11.5 MySQL安装
MySQL的几个常用安装包：rpm、源码、二进制免编译
cd /usr/local/src
wget http://mirrors.sohu.com/mysql/MySQL-5.6/mysql-5.6.35-linux-glibc2.5-x86_64.tar.gz
tar zxvf mysql-5.6.35-linux-glibc2.5-x86_64.tar.gz
mv mysql-5.6.36-linux-glibc2.5-x86_64 /usr/local/mysql
cd /usr/local/mysql
ls
useradd mysql
mkdir /data/
./scripts/mysql_install_db --user=mysql --datadir=/data/mysql
cp support-files/my-default.cnf /etc/my.cnf
datadir=/data/mysql
socket=/tmp/mysql.sock
cp support-files/mysql.server /etc/init.d/mysqld
vi /etc/init.d/mysqld
定义basedir和datadir
basedir=/usr/local/mysql
datadir=/data/mysql
/etc/init.d/mysqld start
ps aux |grep mysql
[root@c-72 mysql]# chkconfig --add mysqld
[root@c-72 mysql]# chkconfig mysqld on
[root@c-72 mysql]# service mysqld stop
Shutting down MySQL.. SUCCESS!
[root@c-72 mysql]# service mysqld start
Starting MySQL. SUCCESS!
[root@c-72 mysql]#
尽量把所有源码包都安装在一个路径。安装大概需要耐心等待一下。
[root@c-72 mysql]# ./scripts/mysql_install_db --user=mysql --datadir=/data/mysql
Installing MySQL system tables..../bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory
[root@c-72 mysql]# yum install libaio* -y //原因：缺少libaio库文件两种方式验证下载是否正确
1.看是否有两个OK
- echo $? 看输出结果是否为0 检验的是 上条命令
cp support-files/mysql.server /etc/init.d/mysqld
basedir=/usr/local/mysql
datadir=/data/mysql
ls -l /etc/init.d/mysqld
chkconfig --add mysqld
service mysqld start
ps aux |grep mysql
netstat -lntp
假如没有办法把启动的脚本放在/ect/init 或者说没有这样的启动脚本模板去拷贝，
killall 先停止读写操作 尽量用killall 慢慢等待
