源码安装mysql5.6.37

MYSQL 源码安装：

修改参数文件：
vi /etc/security/limits.conf
mysql soft nproc 2047
mysql hard nproc 16384
mysql soft nofile 1024
mysql hard nofile 65536
下载5.6.37源码
解压后用cmake安装：
cmake . -DCMAKE_INSTALL_PREEIX=/usr/local/mysql \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DENABLED_LOCAL_INFILE=ON \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWICH_FEDERATED_STORAGE_ENGINE=1 \
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
-DWITHOUT_EXAMPLE_STORAGE_ENGINE=1 \
-DWITH_PARTITION_STORAGE_ENGINE=1 \
-DWITH_PREFSCHEMA_STORAGE_ENGINE=1 \
-DCOMPILATION_COMMENT='JSS for mysqltest' \
-DWITH_READLINE=ON \
-DSYSCONFDIR=/data/mysqldata/3306 \
-DMYSQL_UNIX_ADDR=/data/mysqldata/3306/mysql.sock

编译称重后安装
make && make install

chown -R mysql:mysql /usr/local/mysql
export LANG=zh_CN.CB18030
export PATH=/usr/local/mysql/bin:$PATH

cd /data/
mkdir -p /data/mysqldata/{3306/{data,tmp,binlog},backup,scripts}
chown -R mysql:mysql mysqldata
su - mysql
cd /usr/local/mysql

编辑参数文件
/data/mysqldata/3306/my.cnf

[client]
port = 3306
socket = /data/mysqldata/3306/mysql.sock

#The MySQL server
[mysqld]

#Buffer

#Log

[mysql]

初始化db
/usr/local/mysql/scripts/mysql_install_db --datadir=/data/mysqldata/3306/data --basedir=/usr/local/mysql

此处因为参数文件手敲，出现了错误，需要重新初始化，步骤为：
1 删除/usr/local/mysql/my.cnf
2 删除/data/mysqldata/3306下除了my.cnf外的所有文件，并重新创建此目录下的binlog,data,tmp目录
3 重新运行初始化脚本

启动mysql
mysqld_safe --defaults-file=/data/mysqldata/3306/my.cnf &
netstat -lnt|grep 3306
ps -ef|grep bin/mysql|grep -v grep

设置管理员用户与密码：
mysql
select user,host from mysql.user ;

delete from mysql.user where (user,host) not in (select 'root','localhost');
update mysql.user set user='system',password=password('xxxxxxxxx');
truncate table mysql.db;
flush privileges;
这样就安全了。

以上是mysql使用源码安装和配置root用户的全过程
