# Mysql 5.7.20 源码安装笔记
标签： Linux Mysql
**1、环境说明：**
OS: CentOS 6.9 x86-64
Mysql: mysql-5.7.20.tar.gz
cmake: cmake-3.7.2.tar.gz
**2、OS环境准备**
yum 配置
使用网易源
cd /etc/yum.repo.d/
mkdir backup
mv *.repo ./backup #备份系统默认yum源
wget http://mirrors.163.com/.help/CentOS6-Base-163.repo
运行以下命令生成缓存
yum clean all
yum makecache
软件包安装
yum groupinstall Development tools
yum install –y ncurses ncurses-devel
selinux配置
vi /etc/selinux/config
#SELINUX=enforcing #注释掉
#SELINUXTYPE=targeted #注释掉
SELINUX=disabled #增加
:wq! #保存退出
setenforce 0 #使配置立即生效
getenforce ＃检查配置是否正确
**3、软件准备：**
a、安装约定
软件包存放位置： /usr/local/src
软件安装位置： /usr/local/
b、软件安装包下载
wget https://cdn.mysql.com/archives/mysql-5.7/mysql-5.7.20.tar.gz -P /usr/local/src/
wget https://cmake.org/files/v3.9/cmake-3.9.6.tar.gz -P /usr/local/src
wget https://ufpr.dl.sourceforge.net/project/boost/boost/1.59.0/boost_1_59_0.tar.gz -P /usr/local/src
**4、安装**
a、cmake安装
cd /usr/local/src
tar xf cmake-3.9.6.tar.gz
cd cmake-3.9.6
./configure
make
make install
b、mysql安装
1）、创建mysql用户：
groupadd mysql
useradd -g mysql mysql -s /bin/false #创建用户mysql并加入到mysql组，不允许mysql用户直接登录系统
2）、创建mysql的数据目录
mkdir /mydata/mysql
chown -R mysql:mysql /mydata
3）、安装
cd /usr/local/src
tar zxvf mysql-5.7.20.tar.gz
mkdir /usr/local/boost
cp /usr/local/src/boost_1_59_0.tar.gz /usr/local/boost/ #只需要把boost包放进去就可以，不需要解压
cd /usr/local/src/mysql-5.7.20
cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/mydata/mysql -DSYSCONFDIR=/etc -DMYSQL_USER=mysql -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DENABLED_LOCAL_INFILE=ON -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_FEDERATED_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITHOUT_EXAMPLE_STORAGE_ENGINE=1 -DWITH_EMBEDDED_SERVER=OFF -DWITH_BOOST=/usr/local/boost/
如遇报错，根据错误信息，安装对应包。
yum install xxxxx
rm CMakeCache.txt # 需要删除编译缓存文件
重新编译。
-- Configuring done
-- Generating done
CMake Warning:
Manually-specified variables were not used by the project:
MYSQL_USER
-- Build files have been written to: /usr/local/src/mysql-5.7.20
编译成功。
make
make install
4)、编译选项说明
指定安装文件的安装路径时常用的选项
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql ----指定残可安装路径（默认的就是/usr/local/mysql）
-DMYSQL_DATADIR=/data/mysql ----mysql的数据文件路径
-DSYSCONFDIR=/etc ----配置文件路径
编译过程中启用其他存储引擎时指令介绍
-DWITH_INNOBASE_STORAGE_ENGINE=1 ----使用INNOBASE存储引擎
-DWITH_ARCHIVE_STORAGE_ENGINE=1 ----常应用于日志记录和聚合分析，不支持索引
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 ----黑洞存储引擎
编译过程中取消一些存储引擎指令介绍
-DWITHOUT__STORAGE_ENGINE=1
示例如下：
-DWITHOUT_EXAMPLE_STORAGE_ENGINE=1
-DWITHOUT_FEDERATED_STORAGE_ENGINE=1
-DWITHOUT_PARTITION_STORAGE_ENGINE=1
编译进过程中功能启用的指令介绍
-DWITH_READLINE=1 ----支持批量导入mysql数据
-DWITH_SSL=system ----mysql支持ssl会话，实现基于ssl的数据复
-DWITH_ZLIB=system ----压缩库
-DWITH_LIBWRAP=0 ----是否可以基于WRAP实现访问控制
其他功能指令
-DMYSQL_TCP_PORT=3306 ----默认端口
-DMYSQL_UNIX_ADDR=/tmp/mysql.sock ----默认套接字文件路径
-DENABLED_LOCAL_INFILE=1 ----是否启用LOCAL_INFILE功能
-DEXTRA_CHARSETS=all ----是否支持额外的字符集
-DDEFAULT_CHARSET=utf8 ----默认编码机制
-DDEFAULT_COLLATION=utf8_general_ci ----设定默认语言的排序规则
-DWITH_DEBUG=0 ----DEBUG功能设置
-DENABLE_PROFILING=1 ----性能分析功能是否启用
5）、mysql服务脚本
进入安装目录：
[root@name mysql-5.7.20]# cd /usr/local/src/mysql-5.7.20
[root@name mysql-5.7.20]# cp support-files/mysql.server /etc/init.d/mysqld #从源码包中复制脚本
[root@name mysql-5.7.20]# chmod +x /etc/init.d/mysqld
[root@name mysql-5.7.20]# chkconfig --add mysqld
[root@name mysql-5.7.20]# chkconfig mysqld on
vim /etc/rc.d/init.d/mysqld
basedir=/usr/local/mysql #检查MySQL程序安装路径
datadir=/mydata/mysql #检查MySQl数据库存放目录
:wq! #保存退出
6）、初始化mysql
进入MySQL安装目录
[root@name bin]# cd /usr/local/mysql/bin/
./mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/mydata/mysql/
#生成mysql系统数据库

#server-id错误，在mysql配置文件中【mysqld】增加server-id参数：
vim /etc/my.cnf
[mysqld]
# GENERAL #
server-id = 1
进入数据文件目录，查看文件，若有文件生成，说明初始化成功。
[root@mysql57 mysql]# cd /mydata/mysql
[root@mysql57 mysql]# ls
auto.cnf ib_buffer_pool ibdata1 ib_logfile0 ib_logfile1 mysql performance_schema sys
7)、编辑配置文件：
[root@name db_data]# rm -rf /etc/my.cnf #删除系统默认的配置文件（如果默认没有就不用删除）
[root@mysql mysql]# vim my.cnf #来源mysql安装文档
推荐一个mysql配置文件生成工具，供如我这般小白使用：
https://tools.percona.com/wizard
基于上述配置的my.cnf

8)、环境变量配置
vim /etc/profile #把mysql服务加入系统环境变量：在最后添加下面这一行
export PATH=$PATH:/usr/local/mysql/bin
:wq! #保存退出
source /etc/profile #使配置立刻生效
9）、输出mysql的man手册到man命令的查找路径
vim /etc/man.config
#新增一行
MANPATH /usr/local/mysql/man
10）、输出mysql的库文件
vim /etc/ld.so.conf.d/mysql.conf
/usr/local/mysql/lib/
ldconfig -v
11）、输出mysql的头文件到系统头文件
ln -sv /usr/local/mysql/include/ /usr/include/mysql
"/usr/include/mysql" -> "/usr/local/mysql/include/"
cd /usr/include/mysql/
ls

12）、启动mysql
[root@mysql57 mysql]# service mysqld start
Starting MySQL... SUCCESS!
13)、测试
查看端口
[root@mysql mysql]# netstat -ntulp | grep :3306
tcp 0 0 :::3306 :::* LISTEN 41347/mysqld
登录mysql
[root@mysql57 ~]# mysql
