MySQL 5.7.15 编译安装

1.MySQL的编译安装，需要使用cmake和Boost C++库，因此在进行安装前，需要提前安装好cmake及编译器。

[root@oel6 ~]# yum -y install gcc gcc-c++ ncurses ncurses-devel cmake

2.下载MySQL源代码，选择下载Generic Linux (Architecture Independent), Compressed TAR Archive Includes Boost Headers版本，该版本包含boost库信息，不需要单独下载

[root@oel6 local]# wget http://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-boost-5.7.15.tar.gz

3.添加mysql用户

[root@oel6 local]# groupadd mysql
[root@oel6 local]# useradd -r -g mysql -s /bin/nologin mysql 

4.解压MySQL安装介质

[root@oel6 local]# tar -zxvf mysql-boost-5.7.15.tar.gz 
[root@oel6 local]# cd mysql-5.7.15/

5.编译安装MySQL

[root@oel6 local]# mkdir -p /mysql/data

[root@oel6 local]# cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_DATADIR=/mysql/data \
-DWITH_BOOST=/usr/local/mysql-5.7.15/boost/boost_1_59_0 \

[root@oel6 mysql-5.7.15]# make
[root@oel6 mysql-5.7.15]# make install

清除编译错误信息

[root@oel6 mysql-5.7.15]# make clean
[root@oel6 mysql-5.7.15]# rm CMakeCache.txt

6.初始化MySQL数据库

[root@oel6 ~]# cd /usr/local/mysql/
[root@oel6 mysql]# chown -R mysql:mysql ./
[root@oel6 mysql]# bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/mysql/data

MySQL 5.7.6 之前版本，使用下面命令进行初始化
bin/mysql_install_db --user=mysql

7.启动MySQL数据库 (编译安装的MySQL，会默认创建/etc/my.cnf文件)

[root@oel6 ~]# cd /mysql
[root@oel6 mysql]# mkdir log
[root@oel6 mysql]# mkdir run
[root@oel6 ~]# chown -R mysql:mysql /mysql

[root@oel6 mysql]# cat /etc/my.cnf 
[mysqld]       //非默认参数会影响通过服务方式启停数据库datadir=/mysql/data
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

[mysqld_safe][root@oel6 mysql]# bin/mysqld_safe --user=mysql &
[1] 27572
[root@oel6 mysql]# 2016-10-06T05:21:00.684235Z mysqld_safe Logging to '/mysql/log/mysqld.log'.
2016-10-06T05:21:00.709272Z mysqld_safe Starting mysqld daemon with databases from /mysql/data

8.登陆MySQL数据库

[root@oel6 ~]# vi /root/.bash_profile 
PATH=$PATH:$HOME/bin:/usr/local/mysql/bin //环境变量中增加mysql的路径[root@oel6 ~]# . /root/.bash_profile 

[root@oel6 mysql]# mysql -u root -h localhost -p
Enter password: ;uIY2:ZVrv)uWelcome to the MySQL monitor.  Commands end with ; or \g.

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'oracle';

9.配置MySQL服务自启动

[root@oel6 ~]# cd /usr/local/mysql
[root@oel6 mysql]# cp support-files/mysql.server /etc/init.d/mysqld
[root@oel6 mysql]# chkconfig --add mysqld
[root@oel6 mysql]# chkconfig --list mysqld
mysqld          0:off   1:off   2:on    3:on    4:on    5:on    6:off

10.关闭MySQL数据库

[root@oel6 bin]# mysqladmin -u root shutdown
mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user 'root'@'localhost' (using password: NO)'
[root@oel6 bin]# mysqladmin -u root -p shutdown
Enter password: 
2016-10-06T05:50:46.469848Z mysqld_safe mysqld from pid file /mysql/run/mysqld.pid ended
[1]+  Done                    mysqld_safe --user=mysql

11.通过服务进行MySQL启停

[root@oel6 bin]# service mysqld start
Starting MySQL.                                            [  OK  ]
[root@oel6 bin]# service mysqld stop
Shutting down MySQL.                                       [  OK  ]

12.登陆非默认端口MySQL

[root@oel6 bin]# mysql -u root -P8000 -h localhost -p
Enter password: 
Welcome to the MySQL monitor.  Commands end with ; or \g.
