MySQL5.7单实例二进制包安装方法
一、环境
OS: CentOS release 6.9 (Final)
MySQL: mysql-5.7.20-linux-glibc2.12-x86_64.tar.gz
说明：类似的操作系统也可以的。为了方便起见，涉及到的操作，均可以直接粘贴复制，比较直观快捷的实施，我没有将带有命令行的截图或者文字粘贴出来。
可能会与路径有关，本文档是基于实践而记录下的，可能与你的环境有所不同，请遇到问题，具体分析查找资料。
二、准备工作
2.1、修改主机名称
hostname myserver
sed -i 's/shell/myserver/' /etc/sysconfig/network
2.2、关闭selinux
sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config
setenforce 0
2.3、修改系统内核参数
cat >> /etc/sysctl.conf <<EOF
fs.file-max=655360
fs.aio-max-nr = 1048576
kernel.sem = 5050 646400 5050 128

net.ipv4.tcp_timestamps = 0
net.ipv4.conf.default.accept_source_route = 0
vm.swappiness=1
EOF
# 使其生效
sysctl -p
2.4、安装依赖包
# 需要配置yum
yum clean all
yum -y update
yum -y install gd libxml2-devel libjpeg-devel libpng-devel net-snmp-devel wget telnet vim zip unzip
yum -y install curl-devel libxslt-devel pcre-devel libjpeg libpng libcurl4-openssl-dev

yum -y install perl-DBI perl-DBD-MySQL perl-Time-HiRes perl-IO-Socket-SSL perl perl-devel
yum -y groupinstall "Server Platform Development" "Development tools"
yum -y groupinstall "Development tools"
2.5、基本初始化
mkdir -p /opt/mysql
cd /opt/mysql/
wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.20-linux-glibc2.12-x86_64.tar.gz
tar -zxf mysql-5.7.20-linux-glibc2.12-x86_64.tar.gz
cd /usr/local/
ln -s /opt/mysql/mysql-5.7.20-linux-glibc2.12-x86_64 mysql
2.6、创建所需要的目录
mkdir -p /gomeo2o/data/mysql/mysql_3306/{data,logs,tmp}
mkdir -p /data/backup/
# 更改权限
groupadd mysql
useradd -g mysql mysql -d /home/mysql -s /sbin/nologin
2.7、创建配置文件
# 排除干扰因素
if [ -f /etc/my.cnf ]; then
mv /etc/my.cnf /etc/my.cnf.bak
fi

2.8、初始化数据库
chown -R mysql.mysql /gomeo2o/data
chown -R mysql.mysql /data/backup/
chmod -R 775 /data/backup/
/usr/local/mysql/bin/mysqld --defaults-file=/gomeo2o/data/mysql/mysql_3306/my_3306.cnf --initialize-insecure &
# 查看日志
# tail -f /gomeo2o/data/mysql/mysql_3306/logs/error.log
2.9、启动数据库推荐做法
/usr/local/mysql/bin/mysqld_safe --defaults-file=/gomeo2o/data/mysql/mysql_3306/my_3306.cnf &
2.10、进入mysql,修改账号
/usr/local/mysql/bin/mysql -uroot -p -P3306 -S /gomeo2o/data/mysql/mysql_3306/tmp/mysql_3306.sock
set sql_log_bin = 0;
create user 'rpl_user'@'%';
grant replication slave on *.* to 'rpl_user'@'10.%' identified by 'BR8KLwXCKHgN';
update mysql.user set authentication_string=password('rootpwd2017') where user='root';
flush privileges;
set sql_log_bin = 1;
reset master ; reset slave all;
exit;
######## 配置主从复制方法开始 ########
# CHANGE MASTER TO MASTER_HOST='172.16.1.10',MASTER_USER='rpl_user',
