centos系统下安装MySQL5.7.18方法详解
1、首先安装依赖包
yum install -y gcc gcc-c++ ncurses-devel perl openssl-devel
最最重要的是,不要忘了安装openssl-devel

2、安装cmake
tar -xzvf cmake-3.8.1.tar.gz cd cmake-3.8.1 ./bootstrap make && make install
3、安装MySQL5.7.18
首先下载安装包,本人的安装版本是:mysql-boost-5.7.18.tar.gz
需要下载boost,本人配套的是boost_1_59_0版本
下载,并在/usr/local目录下解压,并重命名为boost
首先为添加 MySQL 对应的系统账户,用于保证其本地文件权限分配:
groupadd mysql useradd -r -g mysql mysql
创建数据库目录:
mkdir -p /var/mysql/data chown mysql:mysql /var/mysql/data
进入解压后的MySQL安装包:
cd mysql-boost-5.7.18 cmake . \ -DCMAKE_INSTALL_PREFIX=/usr/local/mysql/ \ -DINSTALL_DATADIR=/usr/local/mysql/data/master \ -DSYSCONFDIR=/usr/local/mysql/etc \ -DDEFAULT_CHARSET=utf8 \ -DDEFAULT_COLLATION=utf8_general_ci \ -DEXTRA_CHARSETS=all \ -DWITH_SSL=system \ -DWITH_EMBEDDED_SERVER=1 \ -DENABLED_LOCAL_INFILE=1 \ -DWITH_MYISAM_STORAGE_ENGINE=1 \ -DWITH_INNOBASE_STORAGE_ENGINE=1 \ -DWITH_ARCHIVE_STORAGE_ENGINE=1 \ -DWITH_BLACKHOLE_STORAGE_ENGINE=1 \ -DWITH_MEMORY_STORAGE_ENGINE=1 \ -DWITH_FEDERATED_STORAGE_ENGINE=1 \ -DWITH_PARTITION_STORAGE_ENGINE=1 \ -DWITH_PERFSCHEMA_STORAGE_ENGINE=1 \ -DMYSQL_USER=mysql \ -DMYSQL_UNIX_ADDR=/usr/local/mysql/data/mysql.sock \ -DDOWNLOAD_BOOST=1 \ -DWITH_BOOST=/usr/local/boost
如果发生错误,修改好后,需要删除当前目录下的CMakeCache.txt文件,再重新cmake
make && make install
进行完以上步骤,需要改变 mysql 安装目录的所有者,比如我们安装的目录是 /usr/local/mysql,使用命令
chown -R mysql:mysql /usr/local/mysql
修改目录所有者。此时,复制一份默认配置文件
cp /usr/local/mysql/support-files/my-default.cnf /etc/my.cnf
博主安装完成没有my-default.cnf 这个文件,需要自己创建,附上文件的内容:
#For advice on how to change settings please see # http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html # *** DO NOT EDIT THIS FILE. It's a template which will be copied to the # *** default location during install, and will be replaced if you # *** upgrade to a newer version of MySQL.

如果提示已存在文件是否覆盖时,覆盖即可。
然后执行数据库的初始化操作,
/usr/local/mysql/bin/mysqld --initialize --user=mysql,
这时候会初始化数据库并创建一个数据库 root 账号,但是要注意,这个账号是有默认密码的,初始化的时候屏幕上会输出初始化的密码,如果错过了,可以通过查看 /root/.mysql_secret 即可看到默认的密码。
执行 cp /usr/local/mysql/support-files/mysql.server /etc/init.d,将 mysql 的服务启动脚本复制过去,然后执行 service mysql.server start 启动 mysql。
最后 /usr/local/mysql/bin/mysql -rroot -p,输入密码回车,如果出现Access denied for user 'root'@'localhost' (using password: YES),一般情况下
service mysql.server restart 重新启动即可
通过之后,可以用以下命令重新设置root密码
set password=password('你的密码');
至此,基本的安装流程完毕
以下方法可以设置开机启动
命令echo "service mysqld start" >> /etc/rc.local
或者进入/etc/目录,直接vim rc.local编辑rc.local文件,在最后一行添加“service mysqld start”,保存退出。
