centos mysql 编译安装

centos mysql 编译安装

1.安装

创建MySQL用户

sudo  useradd mysql

下载MySQL的源码包，我们这里使用的时5.5.18

安装依赖

sudo yum -y install cmake gcc-c++ make bison-devel ncurses-devel mysql-devel

防止内置的my.cnf捣乱

sudo mv /etc/my.cnf /etc/my.cnf.bak

解压源码包，

cd /home/xiaohe/tools
tar -zxf mysql-5.5.18.tar.gz
cd mysql-5.5.18
cmake -DCMAKE_INSTALL_PREFIX=/home/xiaohe/mysql -DMYSQL_UNIX_ADDR=/home/xiaohe/mysql/mysql.sock -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_EXTRA_CHARSETS:STRING=utf8,gbk -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_READLINE=1 -DENABLED_LOCAL_INFILE=1 -DMYSQL_DATADIR=/home/xiaohe/mysql/data

make -j2 && make -j2 install

-j2 的2 指的是cpu核心数，有几个核心就是几

手动创建目录

cd /home/xiaohe/mysql && mkdir etc tmp var log

创建配置文件

vim etc/my.cnf

[client]
#password   = your_password
port        = 3306
socket      = /home/xiaohe/mysql/mysql.sock

初始化数据库

/home/xiaohe/mysql/scripts/mysql_install_db

完成后启动数据库

/home/xiaohe/mysql/bin/mysqld_safe &

检查一下数据库进程，并登陆一下看看，默认没有密码。

修改mysql密码

mysql
mysql> use mysql;
mysql> UPDATE user SET password=password("123456") WHERE user='root';
mysql> flush privileges;
mysql> exit;

关闭mysql 设置superctl登陆

vim  /home/xiaohe/supervisor/conf/supervisord.conf

[program:mysql-3306]
command= /home/xiaohe/mysql-3306/bin/mysqld --defaults-file=/home/xiaohe/mysql-3306/etc/my.cnf
directory=/home/xiaohe/mysql-3306
user=xiaohe

查看状态

/home/xiaohe/superctl status

加载进去

/home/xiaohe/superctl update

授权

mysql>        grant select,insert,update,delete on *.* to 'root'@'%' identified by '123456' with grant option;

赋予任何主机访问数据的权限 具体根据实际情况授权，以权限最小化为准

mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION
