一.编译安装

1.下载epel源

[[email protected] ~]# wget -O /etc/yum.repos.d/epel.repo https://mirrors.aliyun.com/repo/epel-7.repo

2.安装依赖

[[email protected] ~]# yum install -y ncurses-devel libaio-devel autoconf cmake gcc gcc-c++ glibc

3.解压mysql源码包

[[email protected] ~]# tar xf mysql-5.6.40.tar.gz

4.进去源码包目录

[[email protected] ~]# cd mysql-5.6.40/

5.创建目录

[[email protected] ~]# mkdir /application

6.生成编译文件

[[email protected] mysql-5.6.40]# cmake . -DCMAKE_INSTALL_PREFIX=/application/mysql-5.6.40 #程序存放位置 
-DMYSQL_DATADIR=/application/mysql-5.6.40/data \ 
#数据存放位置
-DMYSQL_UNIX_ADDR=/application/mysql-5.6.40/tmp/mysql.sock #使用utf8字符集
-DDEFAULT_CHARSET=utf8 #校验规则
-DDEFAULT_COLLATION=utf8_general_ci #使用其他额外的字符集
-DWITH_EXTRA_CHARSETS=all \ #支持的存储引擎
-DWITH_INNOBASE_STORAGE_ENGINE=1 \ 
-DWITH_FEDERATED_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 #禁用的存储引擎
-DWITHOUT_EXAMPLE_STORAGE_ENGINE=1 -DWITH_ZLIB=bundled \ #启用zlib库支持（zib、gzib相关）
-DWITH_SSL=bundled \ #启用SSL库支持（安全套接层）
-DENABLED_LOCAL_INFILE=1 \ #启用本地数据导入支持
-DWITH_EMBEDDED_SERVER=1 \ #编译嵌入式服务器支持
-DENABLE_DOWNLOADS=1 \ 
# mysql5.6支持了google的c++mock框架了，允许下载，否则会安装报错。
-DWITH_DEBUG=0 #禁用debug（默认为禁用）

7.编译安装

[[email protected] mysql-5.6.40]# make && make install

8.创建MySQL用户

[[email protected] mysql-5.6.40]# useradd mysql -s /sbin/nologin -M

9.做软链接

[[email protected] mysql-5.6.40]# ln -s /application/mysql-5.6.40 /application/mysql

10.进去其他文件目录

[[email protected] mysql-5.6.40]#  cd /application/mysql/support-files

11.拷贝MySQL配置文件

[[email protected] support-files]# cp my-default.cnf /etc/my.cnf
cp: overwrite ‘/etc/my.cnf’? y

12.拷贝启动脚本

[[email protected] support-files]# cp mysql.server /etc/init.d/mysqld

13.进去初始化目录

[[email protected] support-files]# cd /application/mysql/scripts

14.初始化MySQL

[[email protected] scripts]# ./mysql_install_db --user=mysql --basedir=/application/mysql --datadir=/application/mysql/data

15.创建socket文件所在目录

[[email protected] scripts]# mkdir /application/mysql-5.6.40/tmp

16.授权MySQL服务目录

[[email protected] scripts]# chown -R mysql.mysql /application/mysql*

17.添加环境变量

[[email protected] scripts]# vim /etc/profile.d/mysql.sh
export PATH="/application/mysql/bin:$PATH"

18.加载环境变量

[[email protected] scripts]# source /etc/profile

19.启动MySQL

[[email protected] scripts]# /etc/init.d/mysqld start

20用systemctl管理

[[email protected] ~]# vim /usr/lib/systemd/system/mysqld.service
[Unit]
Description=MySQL Server
Documentation=man:mysqld(8)
Documentation=https://dev.mysql.com/doc/refman/en/using-systemd.html
After=network.target
After=syslog.target
[Install]
WantedBy=multi-user.target
[Service]
User=mysql
Group=mysql
ExecStart=/application/mysql/bin/mysqld --defaults-file=/etc/my.cnf
LimitNOFILE = 5000

[[email protected] ~]# /etc/init.d/mysqld stop
Shutting down MySQL.. SUCCESS!
[[email protected] ~]# systemctl start mysqld

 二.二进制安装

1.解压二进制包

[[email protected] ~]# tar xf mysql-5.6.40-linux-glibc2.12-x86_64.tar.gz 

2.创建MySQL安装目录

[[email protected] ~]# mkdir /application

 3.启动MySQL程序到安装目录下

[[email protected] ~]# mv mysql-5.6.40-linux-glibc2.12-x86_64 /application/mysql-5.6.40

 4.做软链接

[[email protected] ~]# ln -s /application/mysql-5.6.40 /application/mysql

5. 进入其他文件目录

[[email protected] ~]# cd /application/mysql/support-files

 6.拷贝配置文件

[[email protected] support-files]# cp my-default.cnf /etc/my.cnf
cp: overwrite ‘/etc/my.cnf’? y

 7. 拷贝启动脚本

[[email protected] support-files]# cp mysql.server /etc/init.d/mysqld

8.进入初始化目录

[[email protected] support-files]# cd ../scripts/

 9.创建MySQL用户

[[email protected] scripts]# useradd mysql -s /sbin/nologin -M

 10.安装初始化依赖

[[email protected] scripts]# yum install -y autoconf libaio-devel

 11.初始化

[[email protected] scripts]# ./mysql_install_db --user=mysql --basedir=/application/mysql --datadir=/application/mysql/data

 12.启动mysq

[[email protected] scripts]# /etc/init.d/mysqld start

 13.添加环境变量

[[email protected] scripts]# vim /etc/profile.d/mysql.sh
export PATH="/application/mysql/bin:$PATH"

14.修改

[[email protected] scripts]# sed -i ‘s#/usr/local#/application#g‘ /etc/init.d/mysqld /application/mysql/bin/mysqld_safe

 15.用systemctl管理.在/etc/my.cnf添加两行信息

[[email protected] mysql]# cat /etc/my.cnf
basedir = /application/mysql
datadir = /application/mysql/data

 16.启动加入开机自启动

[[email protected] mysql]# /etc/init.d/mysqld stop
[[email protected] mysql]# /etc/init.d/mysqld start
 [[email protected] mysql]# systemctl start mysqld
[[email protected] mysql]# systemctl enable mysqld
