MySQL二进制安装

前提

version　　mysql-5.5

platform　　centos6.x

添加用户

useradd -M -s /sbin/nologin mysql

安装需要的包

yum -y install compat-libstdc++-33.x86_64 libaio.x86_64

安装

tar xzvf mysql-5.5.43-linux2.6-x86_64.tar.gz

mkdir -p /storage/server

mv -f mysql-5.5.43-linux2.6-x86_64 /storage/server/

ln -sf /storage/server/mysql-5.5.43-linux2.6-x86_64 /storage/server/mysql

chown -R mysql:mysql /storage/server/mysql/

# 新建mysql数据目录

mkdir -p /storage/data/mysql

chown -R mysql:mysql /storage/data/mysql

初始化

scripts/mysql_install_db --user=mysql --basedir=/storage/server/mysql --datadir=/storage/data/mysql

修改配置文件

vim /etc/my.cnf

[mysqld]
port            = 3306
socket          = /tmp/mysql.sock
basedir = /storage/server/mysql
datadir = /storage/data/mysql

启动(推荐用mysqld_safe)

/storage/server/mysql/bin/mysqld_safe &

# mysqld_safe默认mysqld的路径为 /usr/local/mysql/bin/mysqld，没有下面步骤用mysqld_safe启动会报错

mkdir -p /usr/local/mysql/bin

ln -sf /storage/server/mysql/bin/mysqld /usr/local/mysql/bin/mysqld

安全设置（根据脚本提示对数据库做一些安全设置）

/storage/server/mysql/bin/mysql_secure_installation
