-# 一、Mysql
-
-#### 1、编译安装mysql5.7
-
-1、清理安装环境：
-
-```shell
-# yum erase mariadb mariadb-server mariadb-libs mariadb-devel -y
-# userdel -r mysql
-# rm -rf /etc/my*
-# rm -rf /var/lib/mysql
-```
-
-2、创建mysql用户
-
-```shell
-[root@mysql-server ~]# useradd -r mysql -M -s /sbin/nologin
--M 不创建用户的家目录
-```
-
-3、从官网下载tar包
-
-wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-boost-5.7.27.tar.gz
-
-4、安装编译工具
-
-```shell
-# yum -y install ncurses ncurses-devel openssl-devel bison gcc gcc-c++ make
-cmake:
-# yum -y install cmake
-```
-
-5、创建mysql目录
-
-```shell
-[root@mysql-server ~]# mkdir -p /usr/local/{data,mysql,log}
-```
-
-6、解压
-
-```shell
-[root@mysql-server ~]# tar xzvf mysql-boost-5.7.27.tar.gz -C /usr/local/
-```
-
-7、编译安装
-
-```shell
-cd 解压的mysql目录
-[root@mysql-server ~]# cd /usr/local/mysql-5.7.27/
-[root@mysql-server mysql-5.7.27]# cmake . \
--DWITH_BOOST=boost/boost_1_59_0/ \
--DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
--DSYSCONFDIR=/etc \
--DMYSQL_DATADIR=/usr/local/mysql/data \
--DINSTALL_MANDIR=/usr/share/man \
--DMYSQL_TCP_PORT=3306 \
--DMYSQL_UNIX_ADDR=/tmp/mysql.sock \
--DDEFAULT_CHARSET=utf8 \
--DEXTRA_CHARSETS=all \
--DDEFAULT_COLLATION=utf8_general_ci \
--DWITH_READLINE=1 \
--DWITH_SSL=system \
--DWITH_EMBEDDED_SERVER=1 \
--DENABLED_LOCAL_INFILE=1 \
--DWITH_INNOBASE_STORAGE_ENGINE=1
-
-参数详解:
--DCMAKE_INSTALL_PREFIX=/usr/local/mysql \   安装目录
--DSYSCONFDIR=/etc \   配置文件存放 （默认可以不安装配置文件）
--DMYSQL_DATADIR=/usr/local/mysql/data \   数据目录   错误日志文件也会在这个目录
--DINSTALL_MANDIR=/usr/share/man \     帮助文档 
--DMYSQL_TCP_PORT=3306 \     默认端口
--DMYSQL_UNIX_ADDR=/tmp/mysql.sock \  sock文件位置，用来做网络通信的，客户端连接服务器的时候用
--DDEFAULT_CHARSET=utf8 \    默认字符集。字符集的支持，可以调
--DEXTRA_CHARSETS=all \   扩展的字符集支持所有的
--DDEFAULT_COLLATION=utf8_general_ci \  支持的
--DWITH_READLINE=1 \    上下翻历史命令
--DWITH_SSL=system \    使用私钥和证书登陆（公钥）  可以加密。 适用与长连接。坏处：速度慢
--DWITH_EMBEDDED_SERVER=1 \   嵌入式数据库
--DENABLED_LOCAL_INFILE=1 \    从本地倒入数据，不是备份和恢复。
--DWITH_INNOBASE_STORAGE_ENGINE=1  默认的存储引擎，支持外键
