MySql的编译安装

一 前期准备

1 cmake包，要求2.8以上版本

https://cmake.org/download/

2 boost库包

boost Boost库是一个可移植、提供源代码的C++库，作为标准库的后备，是C++标准化进程的开发引擎之一

https://www.boost.org/

3 mysql包

https://dev.mysql.com/downloads/mysql/5.7.html

二 mysql安装

1 安装依赖包

yum -y install ncurses-devel gcc-\* bzip2-\* bison

2 cmake install

tar xf cmake-3.6.0-rc1.tarcd cmake-3.6.0-rc1./configuremakemake install

3 boost

tar xf boost_1_59_0.tar.bz2mv boost_1_59_0 /usr/local/boost

4 mysql

useradd -s /sbin/nologin -r mysqlmkdir -pv /usr/local/mysql/datatar xf mysql...tar.xxcmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \-DMYSQL_DATADIR=/usr/local/mysql/data/ \-DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock  \-DWITH_INNOBASE_STORAGE_ENGINE=1 \-DWITH_MYISAM_STORAGE_ENGINE=1  \-DENABLED_LOCAL_INFILE=1 \-DEXTRA_CHARSETS=all -DDEFAULT\_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general\_ci \-DMYSQL_USER=mysql \-DWITH_DEBUG=0 \-DWITH_EMBEDDED_SERVER=1 \-DDOWNLOAD_BOOST=1  -DENABLE_DOWNLOADS=1 -DWITH_BOOST=/usr/local/boostmakemake install

##解释
cmake . \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql     指定安装路径
-DMYSQL_DATADIR=/usr/local/mysql/data/     指定数据目录
-DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock      指定sock文件路径
-DWITH_INNOBASE_STORAGE_ENGINE=1             安装Innodb存储引擎
-DWITH_MYISAM_STORAGE_ENGINE=1              安装myisam存储引擎
-DENABLED_LOCAL_INFILE=1                 允许使用Load data命令从本地导入数据
-DEXTRA_CHARSETS=all -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci   安装所有字符集、默认字符集utf-8 、校验字符
-DMYSQL_USER=mysql   mysql用户名
-DWITH_DEBUG=0       关闭debug
-DWITH_EMBEDDED_SERVER=1   生成一个libmysqld.a(.so)的库，这个库同时集成了mysql服务与客户端API
-DDOWNLOAD_BOOST=1  -DENABLE_DOWNLOADS=1 -DWITH_BOOST=/usr/local/boost   允许boost 允许下载boost库文件

5 安装后操作

cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql
chmod 755 /etc/init.d/mysql
chown mysql.mysql /usr/local/mysql/ -R
ln -sf /usr/local/mysql/bin/* /usr/bin/
ln -sf /usr/local/mysql/lib/* /usr/lib/
ln -sf /usr/local/mysql/libexec/*  /usr/local/libexec
ln -sf /usr/local/mysql/share/man/man1/*  /usr/share/man/man1
ln -sf /usr/local/mysql/share/man/man8/*  /usr/share/man/man8修改配置文件   确保路径正确
[root@web01 ~]# egrep -v "^#|^$" /etc/my.cnf
[mysqld]
datadir=/usr/local/mysql/data
socket=/usr/local/mysql/mysql.sock
symbolic-links=0
[mysqld_safe]
log-error=/var/log/mysql.log
pid-file=/var/run/mysql.pid
!includedir /etc/my.cnf.d

6 初始化数据库

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

7 启动mysql

[root@web01 ~]# /etc/init.d/mysql start

8 密码修改

[root@web01 ~]# mysql_secure_installation
