知识点017-编译安装mysql

1、下载源码包

wget http://mirrors.sohu.com/mysql/MySQL-5.6/mysql-5.6.35-linux-glibc2.5-x86_64.tar.gz

2、解压源码包

[root@aliyun software]# tar -xzvf mysql-5.6.35-linux-glibc2.5-x86_64.tar.gz

3、复制解压后的mysql目录

[root@aliyun software]# mv mysql-5.6.35-linux-glibc2.5-x86_64 /usr/local/mysql

4、添加用户组和用户

groupadd mysql

useradd -g mysql mysql

5、安装

切换目录：[root@aliyun software]# cd /usr/local/mysql/

更改权限：chown -R mysql:mysql ./

./scripts/mysql_install_db --user=mysql --datadir=/usr/local/mysql/data/mysql

[root@aliyun mysql]# ./scripts/mysql_install_db --user=mysql --datadir=/usr/local/mysql/data

[root@aliyun mysql]# cp support-files/mysql.server /etc/init.d/mysqld

[root@aliyun mysql]# chmod 755 /etc/init.d/mysqld

[root@aliyun mysql]# cp support-files/my-default.cnf /etc/my.cnf

6、修改启动脚本

[root@aliyun mysql]# vim /etc/init.d/mysqld

 

7、测试链接

[root@aliyun local]# pwd
/usr/local
[root@aliyun local]# ./mysql/bin/mysql -uroot

 

8、加入环境变量

编辑 /etc/profile，这样能够在任何地方用mysql命令了

 [root@aliyun local]# vim /etc/profile

在最后添加

[root@aliyun local]# source /etc/profile

9、启动、关闭、状态

启动mysql

service mysqld start

关闭mysql

service mysqld stop

查看运行状态

service mysqld status

10、报错问题处理

[ERROR] Fatal error: Can't open and lock privilege tables: Table 'mysql.user' doesn't exist。

[root@aliyun local]# more /etc/my.cnf |grep -v ^#

正常状况下为空值

[client]
socket=/usr/local/mysql/data/mysql/mysql.sock
[mysqld]
datadir=/usr/local/mysql/data/mysql
socket=/usr/local/mysql/data/mysql/mysql.sock
user=mysql
old_passwords=1

[mysqld_safe]
log-error=/usr/local/mysql/data/mysql/mysqld.log
pid-file=/usr/local/mysql/data/mysql/mysqld.pid
 

#因为编译安装时指定的路径为/opt/data以及mysql_install_db时指定的datadir也为/opt/data,而my.cnf为缺省的路径
#所以修改datadir至正确路径后，问题解决

操做命令记录

tar -xf mysql-5.6.33-linux-glibc2.5-x86_64.tar.gz 
ls
mv mysql-5.6.33-linux-glibc2.5-x86_64 /usr/local/mysql
id mysql
groupadd mysql
useradd -g mysql mysql
id mysql
df -h
cd
cd /app
ls
mkdir data
chown -R mysql.mysql data
ll
cd /usr/local/mysql/
ls
cd scripts/
ls
./mysql_install_db --basedir=/usr/local/mysql/ --datadir=/app/data/
ll /app/data/
cd ../
ls
cd support-files/
ls
cp mysql.server /etc/init.d/mysqld
cd
chmod 755 /etc/init.d/mysqld 
vi /etc/my.cnf 
[client]
socket=/app/data/mysql.sock
[mysqld]
server_id=1
datadir=/app/data
basedir=/usr/local/mysql
socket=/app/data/mysql.sock
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

[mysqld_safe]
log-error=/app/data/mysqld.log
pid-file=/app/data/mysqld.pid
/etc/init.d/mysqld start
mysql
/usr/local/mysql/bin/mysql
