Centos 7下编译安装Mysql

(1)官网下载地址：https://dev.mysql.com/downloads/mysql/

此处下载的是 mysql-boost-5.7..tar.gz

百度云下载地址：https://pan.baidu.com/s/1wDAJawz2hUEMbzOVte-bdQ

提取码：gfqo

(2)安装依赖包

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

(3)解压源码包并配置

cd /usr/local/src

tar -zxf mysql-boost-5.7..tar.gz

cd mysql-5.7./

cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_DATADIR=/usr/local/mysql/data \
-DSYSCONFDIR=/usr/local/mysql \
-DWITH_MYISAM_STORAGE_ENGINE= \
-DWITH_INNOBASE_STORAGE_ENGINE= \
-DWITH_MEMORY_STORAGE_ENGINE= \
-DWITH_READLINE= \
-DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock \
-DMYSQL_TCP_PORT= \
-DENABLED_LOCAL_INFILE= \
-DWITH_PARTITION_STORAGE_ENGINE= \
-DEXTRA_CHARSETS=all \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_BOOST=boost

以下为上述配置的说明

cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \     安装根目录
-DMYSQL_DATADIR=/data//data \                 数据存储目录
-DSYSCONFDIR=/data/ \                               配置文件(my.cnf)目录 (貌似没用，配置文件依然在/etc/my.cnf)
-DWITH_MYISAM_STORAGE_ENGINE= \               编译myisam存储引擎，默认的存储引擎，不加也可以
-DWITH_INNOBASE_STORAGE_ENGINE= \             支持InnoDB存储引擎，这个也是默认安装的
-DWITH_MEMORY_STORAGE_ENGINE= \               支持MEMORY引擎
-DWITH_READLINE= \                                            使用readline功能
-DMYSQL_UNIX_ADDR=/data//mysql.sock \     sock存放到/data/3306目录
-DMYSQL_TCP_PORT= \                        数据库端口
-DENABLED_LOCAL_INFILE= \                      可以使用load data infile命令从本地导入文件
-DWITH_PARTITION_STORAGE_ENGINE= \      安装数据库分区
-DEXTRA_CHARSETS=all \                              支持所有字符集
-DDEFAULT_CHARSET=utf8 \                    默认字符集
-DDEFAULT_COLLATION=utf8_general_ci \       设置默认效验字符集排序规则，要和DDEFAULT_CHARSET一起用
-DWITH_BOOST=boost    从MySQL 5.7.5开始Boost库是必需的

(4)编译及安装

make && make install

（5）添加用户和组

groupadd mysql

useradd -g mysql mysql

chown -R mysql:mysql /usr/local/mysql

(6)初始化

cd /usr/local/mysql/bin

./mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data/

注意：初始化完了需要记住root密码

出现以下说明初始化成功

（7）写入环境变量

echo "export PATH=$PATH:/usr/local/mysql/bin" >> /etc/profile

source /etc/profile

(8)修改配置文件

vim /etc/my.cnf

配置如下：

[mysqld]
basedir = /usr/local/mysql
datadir = /usr/local/mysql/data
socket = /usr/local/mysql/mysql.sock
user = mysql
symbolic-links=

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

(9)创建日志文件并赋予权限

mkdir -p /usr/local/mysql/log-error/

touch /usr/local/mysql/log-error/mariadb.log

chown -R mysql:mysql /usr/local/mysql/log-error/mariadb.log

(10)启动Mysql

/usr/local/mysql/support-files/mysql.server start

(11)设置用户密码及权限

登录mysql:

mysql -u root -p

修改root用户密码：

SET PASSWORD = PASSWORD('');
ALTER USER 'root'@'localhost' PASSWORD EXPIRE NEVER;
FLUSH PRIVILEGES;

授权所有用户：

grant all privileges on *.* to 'root'@'%' identified by '' with grant option;  
flush privileges;

查询数据库的用户：

use mysql;
SELECT DISTINCT CONCAT('User: ''',user,'''@''',host,''';') AS query FROM mysql.user;
quit; #退出mysql命令行

(12)设置为开机自动启动Mysql

vim /etc/rc.d/rc.local

添加标准启动命令：

/usr/local/mysql/support-files/mysql.server start

给/etc/rc.d/rc.local添加可执行权限

chmod +x /etc/rc.d/rc.local
