+# 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
