源码安装MySQL比较麻烦，需要安装依赖包，然后进行编译，时间较长，建议安装二进制的MySQL，时间比较快；

榆次ssl适用于网站、小程序/APP、API接口等需要进行数据传输应用场景，ssl证书未来市场广阔！成为创新互联公司的ssl证书销售渠道，可以享受市场价格4-6折优惠！如果有意向欢迎电话联系或者加微信：18982081108（备注：SSL证书合作）期待与您的合作！

用到的软件包：

mysql-5.7.18.tar.gz

boost_1_59_0.tar.gz

1、安装依赖包

yum -y install gcc* gcc-c++ ncurses* ncurses-devel* cmake* bison* libgcrypt* perl*

2、创建MySQL用户：

[root@localhost ~]# mkdir -p /mysql/data

[root@localhost ~]# mkdir -p /mysql/mysql5718

[root@localhost ~]# chown -R mysql.mysql /mysql/

3、调整系统参数

[root@localhost ~]# vim /etc/security/limits.conf

   *   soft   nproc   65535

   *   hard   nproc   65535

   *   soft   nofile   65535

   *   hard   nofile   65535

[root@localhost ~]# vi /etc/security/limits.d/20-nproc.conf

   *   soft   nproc   65535

[root@localhost ~]#  vi /etc/profile

   ulimit -u 65535

   ulimit -n 65535

4、下载并解压软件

[root@localhost ~]# tar zxvf mysql-5.7.18.tar.gz -C /usr/src/

[root@localhost ~]# tar zxvf boost_1_59_0.tar.gz -C /mysql/

[root@localhost ~]# chown -R mysql.mysql /mysql/

[root@localhost ~]# chmod -R 755  /mysql/

[root@localhost ~]# chown -R mysql.mysql /usr/src/mysql-5.7.18/

5、开始编译安装MySQL5.7.18

[root@localhost ~]# su - mysql

[mysql@localhost ~]$ cd /usr/src/mysql-5.7.18/

[mysql@localhost mysql-5.7.18]$cmake . -DCMAKE_INSTALL_PREFIX=/mysql/mysql5718 \

-DMYSQL_DATADIR=/mysql/data \

-DDOWNLOAD_BOOST=1 \

-DWITH_BOOST=/mysql/boost_1_59_0

[mysql@localhost mysql-5.7.18]$ make -j 4   （并行4个进程同时进行编译）

[mysql@localhost mysql-5.7.18]$ make  install

6、初始化数据库：

[mysql@localhost ~]$ /mysql/mysql5718/bin/mysqld --initialize --user=mysql --basedir=/mysql/mysql5718/ --datadir=/mysql/data/

---注意，在初始化数据库会生成数据库的默认密码，这个密码要记住，一会登录数据库要用

7、编辑my.cnf配置文件，启动数据库

[mysql@localhost ~]$ vim my.cnf   （该配置文件仅供参考）

 [mysql@localhost ~]$  /mysql/mysql5718/bin/mysqld_safe --defaults-file=/mysql/data/my.cnf  --user=mysql &

8、进入数据库检查：

 [mysql@localhost ~]$  /mysql/mysql5718/bin/mysql -u root -p --socket=/mysql/data/mysql.sock

 Enter password:

然后重新登录数据库，进行检查：

[mysql@localhost ~]$  /mysql/mysql5718/bin/mysql -u root -p --socket=/mysql/data/mysql.sock

 Enter password:
