mysql5.7.32
源码编译安装
MySQL 5.7主要特性：
原生支持Systemd
更好的性能：对于多核CPU、固态硬盘、锁有着更好的优化
更好的InnoDB存储引擎
更为健壮的复制功能：复制带来了数据完全不丢失的方案，传统金融客户也可以选择使用MySQL数据库。
注：mysql-5.6.3已经支持了多线程的主从复制新增sys库：以后这会是DBA访问最频繁的库
安装前提环境
[root@mysql ~]# wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
[root@mysql ~]# yum grouplist
[root@mysql ~]# yum groupinstall Development Tools -y
[root@mysql ~]# yum -y groupinstall base
[root@mysql ~]# yum -y install gcc-c++ gcc m4 openssl-devel
因为centos7.2默认安装了mariadb-libs，所以先要卸载掉
查看是否安装mariadb
[root@mysql ~]# rpm -qa | grep mariadb
mariadb-libs-5.5.60-1.el7_5.x86_64
卸载mariadb
[root@mysql ~]# rpm -e mariadb-libs
error: Failed dependencies:
libmysqlclient.so.18()(64bit) is needed by (installed) postfix-2:2.10.1-7.el7.x86_64
libmysqlclient.so.18(libmysqlclient_18)(64bit) is needed by (installed) postfix-2:2.10.1-7.el7.x86_64
[root@mysql ~]# rpm -e mariadb-libs --nodeps
安装依赖包
cmake：由于从MySQL5.5版本开始弃用了常规的configure编译方法，所以需要CMake编译器，用于设置mysql的编译参数。如：安装目录、数据存放目录、字符编码、排序规则等。Boost #从MySQL 5.7.5开始Boost库是必需的，mysql源码中用到了C++的Boost库，要求必须安装boost1.59.0或以上版本
GCC是Linux下的C语言编译工具，mysql源码编译完全由C和C++编写，要求必须安装GCC bison：Linux下C/C++语法分析器
ncurses：字符终端处理库
文件准备：
ncurses-6.2.tar.gz ftp://ftp.gnu.org/gnu/ncurses/
bison-3.6.3.tar.gz http://ftp.gnu.org/gnu/bison/
cmake-3.18.1.tar.gz http://www.cmake.org/download/
boost_1_59_0.tar.gz wget http://nchc.dl.sourceforge.net/project/boost/boost/1.59.0/boost_1_59_0.tar.gz
mysql-5.7.32.tar.gz wget http://cdn.mysql.com/Downloads/MySQL-5.7/mysql- 5.7.32.tar.gz
安装CMAKE及必要的软件：
[root@mysql ~]# tar zxf cmake-3.18.1.tar.gz
[root@mysql cmake-3.18.1]# cd cmake-3.18.1/
[root@mysql cmake-3.18.1]# ./bootstrap
[root@mysql cmake-3.18.1]# gmake && gmake install
[root@mysql ~]# tar zxf bison-3.6.3.tar.gz
[root@mysql ~]# cd bison-3.6.3/
[root@mysql bison-3.6.3]# ./configure && make && make install
[root@mysql ~]# tar zxf ncurses-6.2.tar.gz
[root@mysql ~]# cd ncurses-6.2/
[root@mysql ncurses-6.2]# ./configure && make && make insatll
[root@mysql ~]# tar zxf boost_1_59_0.tar.gz
[root@mysql ~]# mv boost_1_59_0 /usr/local/boost
创建mysql用户和用户组及目录
[root@mysql ~]# groupadd -r mysql && useradd -r -g mysql -s /bin/fslse -M mysql
[root@mysql ~]# mkdir /usr/local/mysql
[root@mysql ~]# mkdir /usr/local/mysql/data
编译安装mysq
**解压mysql源码包：**
[root@mysql ~]# tar zxf mysql-5.7.32.tar.gz
[root@mysql mysql-5.7.32]# cd mysql-5.7.32/
**执行cmake命令进行编译前的配置：**
[root@mysql mysql-5.7.32]# cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/usr/local/mysql/data -DSYSCONFDIR=/etc -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DEXTRA_CHARSETS=all -DMYSQL_UNIX_ADDR=/tmp/mysql.sock -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_ARCHIVE_STORAGE_ENGINE=1 -DWITH_PARTITION_STORAGE_ENGINE=1 -DWITH_SYSTEMD=1 -DWITH_BOOST=/usr/local/boost
**查看cpu**
[root@mysql mysql-5.7.32]# cat /proc/cpuinfo |grep processor
processor : 0
processor : 1
processor : 2
processor : 3
[root@mysql mysql-5.7.32]# cat /proc/cpuinfo |grep processor | wc -l
4
为了加快编译速度可以按下面的方式编译安装
**开始编译、编译安装：**
[root@mysql mysql-5.7.32]# make -j 4 && make install (等同于make && make install)
-j参数表示根据CPU核数指定编译时的线程数，可以加快编译速度。默认为1个线程编译。注3：若要重新运行cmake配置，需要删除CMakeCache.txt文件
#make clean
#rm -f CMakeCache.txt
配置解释：
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql [MySQL安装的根目录]
-DMYSQL_DATADIR=/usr/local/mysql /data [MySQL数据库文件存放目录]
-DSYSCONFDIR=/etc [MySQL配置文件所在目录]
-DWITH_MYISAM_STORAGE_ENGINE=1 [添加MYISAM引擎支持]
-DWITH_INNOBASE_STORAGE_ENGINE=1[添加InnoDB引擎支持]
-DWITH_ARCHIVE_STORAGE_ENGINE=1 [添加ARCHIVE引擎支持]
-DMYSQL_UNIX_ADDR=/usr/local/mysql /mysql.sock [指定mysql.sock位置]
-DWITH_PARTITION_STORAGE_ENGINE=1 [安装支持数据库分区]
-DEXTRA_CHARSETS=all [使MySQL支持所有的扩展字符]
-DDEFAULT_CHARSET=utf8[设置MySQL的默认字符集为utf8]
-DDEFAULT_COLLATION=utf8_general_ci [设置默认字符集校对规则]
-DWITH-SYSTEMD=1 [可以使用systemd控制mysql服务]
-DWITH_BOOST=/usr/local/boost [指向boost库所在目录]

总结：
SSL(Secure Sockets Layer 安全套接层),及其继任者传输层安全（Transport Layer Security，TLS）是为网络通信提供安全及数据完整性的一种安全协议。复制默认是明文进行传输的，通过SSL加密可以大大提高数据的安全性。
