篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了CentOS7.5源码安装MySQL5.7.28多实例相关的知识，希望对你有一定的参考价值。

由于环境的需要，一个实例所有表要区分大小表，另一个实例不区分。部署过来也参数了很多资料，也遇到些坑，这里将我的部署记录下来，以便大家参考，操作过程如有不当之处，还请指点，谢谢！！
具体部署过程记录如下：

安装环境准备
1.1 主机环境准备
1.1.1. HOST
配置每台主机的hosts(/etc/hosts),添加host_ip $hostname到/etc/hosts文件中。

[root@~]# echo " 192.168.8.100 multidb" >> /etc/hosts

1.1.2. 关闭selinux

[root@~]# sed -i ‘s/SELINUX=enforcing/SELINUX=permissive/g‘ /etc/selinux/config
[root@~]# setenforce 0

1.1.3. 系统主机时间、时区、系统语言
? 修改时区

[root@~]# ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

? 修改系统语言环境

[root@~]# echo ‘LANG="en_US.UTF-8"‘ >> /etc/profile 
[root@~]# source /etc/profile

? 配置主机NTP时间同步

[root@~]# yum -y install ntp
[root@~]# systemctl enable ntpd
[root@~]# systemctl start ntpd
[root@~]# echo ‘server ntp1.aliyun.com‘ >> /etc/ntp.conf
[root@~]# echo ‘server ntp2.aliyun.com‘ >> /etc/ntp.conf

mysql安装部署
2.1 环境清理

[root@~]# rpm -e --nodeps mariadb-libs-*
[root@~]# rpm -e mysql*
[root@~]# yum list installed | grep mariadb     ---确认已经清理干净
[root@~]# yum list installed | grep mysql       ---确认已经清理干净
[root@~]# mv /etc/my.cnf /etc/my.cnf.`date +%Y%m%d%H%M%S`.bak

2.2 安装依赖包

[root@~]# yum -y install bzr zlib-devel gcc-c++ ncurses ncurses-devel libev make cmake gcc autoconf automake zlib libxml libgcrypt libtool bison perl perl-devel libaio libaio-devel perl-Time-HiRes perl-DBD-MySQL perl-Digest-MD5 rsync perl-Data-Dumper net-tools wget vim openssl openssl-devel

2.3 创建用户

[root@~]# groupadd mysql
[root@~]# useradd mysql -g mysql -s /sbin/nologin -M

2.4 配置系统内核参数

[root@~]# vi /etc/sysctl.conf
net.core.somaxconn = 65535
net.core.netdev_max_backlog = 65535
net.ipv4.tcp_max_syn_backlog = 65535

net.ipv4.neigh.default.gc_thresh3=8192
kernel.shmmax = 25769803774
kernel.shmmni = 4096
kernel.shmall = 16777216
kernel.sem = 1010 129280 1010 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 4194304
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
fs.aio-max-nr = 1048576
fs.file-max = 6815744
[root@~]# modprobe br_netfilter
[root@~]# sysctl -p

2.5 修改系统资源限制

[root@~]# vi /etc/security/limits.conf
mysql  soft    nproc   65535
mysql  hard    nproc   65535
mysql  soft    nofile  65535
mysql  hard    nofile  65535
mysql  soft    stack   10240

2.6 修改环境变量

[root@~]# vi /etc/profile
if [ $USER = "mysql" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
[root@~]# source /etc/profile

2.7 安装mysql多实例
2.7.1. 创建软件安装目录(部署路径请根据实际修改)

[root@~]# mkdir -pv /data/mysql/{3306,3307}
[root@~]# mkdir -v /data/mysql/3306/{logs,data,binlog}
[root@~]# mkdir -v /data/mysql/3307/{logs,data,binlog}

2.7.2. boost源码包下载

[root@opt~]# cd /opt
[root@opt~]# wget -c  http://www.sourceforge.net/projects/boost/files/boost/1.59.0/boost_1_59_0.tar.gz
[root@opt~]# tar zxvf boost_1_59_0.tar.gz

2.7.4.  配置MySQL环境变量

[root@~]# echo ‘export PATH=/usr/local/mysql/bin:$PATH‘ >> /etc/profile
[root@~]# tail -1 /etc/profile
[root@~]# source /etc/profile

2.7.5.  MySQL参数配置
