- 编译安装
./bootstrap
make && make install
安装boost
- 在/usr/local下创建boost文件夹
mkdir -p /usr/local/boost

1 CMake安装mysql时报错
CMake Error at cmake/readline.cmake:85 (MESSAGE):
Curses library not found. Please install appropriate package,
解决
yum -y install ncurses-devel
rm -rf CMakeCache.txt
mysql配置
- 创建mysql运行使用的用户mysql
/usr/sbin/groupadd mysql
/usr/sbin/useradd -g mysql mysql
- 创建binlog和库的存储路径并赋予mysql用户权限
mkdir -p /usr/local/webserver/mysql/binlog /www/data_mysql
chown mysql.mysql /usr/local/webserver/mysql/binlog/ /www/data_mysql/
- 将mysql文件夹的权限给mysql用户
chown -R mysql /usr/local/webserver/mysql
chgrp -R mysql /usr/local/webserver/mysql
- 创建my.cnf配置文件
vim /etc/my.cnf
- my.cnf文件里内容如下

- 初始化数据库
cd /usr/local/webserver/mysql/
执行
/usr/local/webserver/mysql/scripts/mysql_install_db --defaults-file=/etc/my.cnf --user=mysql
- 创建开机启动脚本
cd /usr/local/webserver/mysql/
cp support-files/mysql.server /etc/rc.d/init.d/mysqld
chkconfig --add mysqld
chkconfig --level 35 mysqld on
- 启动mysql
service mysqld start
- 连接mysql
/usr/local/webserver/mysql/bin/mysql -u root -p
如果看到如果下，，则成功
mysql>
看一下数据库
mysql> show databases;

ok~~~~~~
- 修改mysql密码
进入mysql命令行
格式：SET PASSWORD FOR '用户名'@'主机' = PASSWORD(‘密码');
SET PASSWORD FOR 'root'@'localhost' = PASSWORD('root');
创建用户并授权
grant all privileges on *.* to 用户名@'%' identified by '密码' with grant option;
grant all privileges on *.* to root@'%' identified by 'root' with grant option;
测试mysql用户名和密码修改是否生效
连接mysql
会要输入密码，输入刚才设置的密码（root），如果能连接mysql，说明设置成功
同一个局域网连接mysql
用navicat连接连接mysql
备注：
连接名：随便起
主机名或ip地址：虚拟机的ip地址
Linux命令行获取：ip addr
端口号：mysql的端口号 3306
用户名：root
密码：root
连接测试，
不出意外会失败,原因
1）Linux的防火墙没有关闭
关闭防火墙
systemctl stop firewalld，systemctl disable firewalld
2） 服务器上登录mysql，查看是否有地址限制，
语法：
use mysql;
select host,user from user;
grant all privileges on *.* to 'root'@'%' identified by '密码';
flush privileges;
操作如下：
mysql> select host,user from user ;
mysql> grant all privileges on *.* to 'root'@'%' identified by 'root';
mysql> flush privileges;
全部操作及显示：
mysql> use mysql ;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
mysql> select host,user from user ;
+-----------------------+------+
| host | user |
+-----------------------+------+
| % | root |
| 127.0.0.1 | root |
| ::1 | root |
| localhost | |
| localhost | root |
| localhost.localdomain | |
| localhost.localdomain | root |
+-----------------------+------+
7 rows in set (0.02 sec)

现在开始开心的使用mysql吧~~~~~~
