CentOS7.5源碼安裝MySQL5.7.28多實例

原創 love8度幸福 2019-12-31 13:48

由於環境的需要，一個實例所有表要區分大小表，另一個實例不區分。部署過來也參數了很多資料，也遇到些坑，這裏將我的部署記錄下來，以便大家參考，操作過程如有不當之處，還請指點，謝謝！！
具體部署過程記錄如下：

  1. 安裝環境準備
    1.1 主機環境準備
    1.1.1. HOST
    配置每臺主機的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. 關閉selinux

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

1.1.3. 系統主機時間、時區、系統語言
 修改時區

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

 修改系統語言環境

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

 配置主機NTP時間同步

[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
  1. Mysql安裝部署
    2.1 環境清理 
    [root@~]# rpm -e --nodeps mariadb-libs-*
[root@~]# rpm -e mysql*
[root@~]# yum list installed | grep mariadb     ---確認已經清理乾淨
[root@~]# yum list installed | grep mysql       ---確認已經清理乾淨
[root@~]# mv /etc/my.cnf /etc/my.cnf.`date +%Y%m%d%H%M%S`.bak

    2.2 安裝依賴包

[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 創建用戶

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

2.4 配置系統內核參數

[root@~]# vi /etc/sysctl.conf
net.core.somaxconn = 65535
net.core.netdev_max_backlog = 65535
net.ipv4.tcp_max_syn_backlog = 65535
net.ipv4.tcp_fin_timeout = 10
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_tw_recycle = 1
net.ipv4.tcp_keepalive_time = 120
net.ipv4.tcp_keepalive_intvl = 30
net.ipv4.tcp_keepalive_probes = 3
vm.swappiness = 0
net.ipv4.ip_forward=1
net.bridge.bridge-nf-call-iptables=1
net.ipv4.neigh.default.gc_thresh1=4096
net.ipv4.neigh.default.gc_thresh2=6144
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 修改系統資源限制

[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 修改環境變量

[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 安裝mysql多實例
2.7.1. 創建軟件安裝目錄(部署路徑請根據實際修改)

[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源碼包下載

[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
[root@opt~]# mv boost_1_59_0 /usr/local/boost

2.7.3. 下載並編譯安裝MySQL5.7.28
[root@opt~]# cd /opt```

[root@opt~]# wget -c https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-boost-5.7.28.tar.gz
[root@opt~]# tar zxvf mysql-boost-5.7.28.tar.gz

2.7.4.  配置MySQL環境變量

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

2.7.5.  MySQL參數配置
（1）server_id=3306與server_id=3307數值請根據實際配置，注意配置的id值與局域網內其他各實例所配置的數值不可以衝突；
