CentOS7.X源码方法安装MySQL5.7.28多实例

前面有文章介绍使用mysql_multi的方式来部署MySQL5.7.28多实例
CentOS7.X使用mysql_multi部署MySQL5.7.28多实例

本文给大家介绍如何使用源码的方式来安装部署多实例，具体操作过程如下所描述：

1 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。

[[email protected]~ ]# echo "192.168.8.100 multidb" >> /etc/hosts

1.1.2. 关闭selinux

[[email protected]~ ]# sed -i 's/SELINUX=enforcing/SELINUX=permissive/g' /etc/selinux/config
[[email protected]~ ]# setenforce 0

1.1.3. 系统主机时间、时区、系统语言 修改时区

[[email protected]~ ]# ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

 修改系统语言环境

[[email protected]~ ]# echo 'LANG="en_US.UTF-8"' >> /etc/profile 
[[email protected]~ ]# source /etc/profile

 配置主机NTP时间同步

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

2 Mysql安装部署
2.1 环境清理

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

2.2 安装依赖包

[[email protected]~ ]# 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

[[email protected]~ ]# groupadd mysql
[[email protected]~ ]# useradd mysql -g mysql -s /sbin/nologin -M

2.4 配置系统内核参数

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

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
[[email protected]~ ]# modprobe br_netfilter
[[email protected]~ ]# sysctl -p

2.5 修改系统资源限制

[[email protected]~ ]# 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

[[email protected]~ ]# 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
[[email protected]~]# 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)
