MySQL如何进行安装部署

本篇文章给大家介绍一下MysqL进行安装部署的方法。有一定的参考价值，有需要的朋友可以参考一下，希望对大家有所帮助。

MysqL安装部署

1.二进制安装

1.清除残留软件

rpm -qa|grep mariadb
yum remove mariadb-libs -y
rm -rf /etc/my.cnf

2.下载软件包安装依赖

wget https://downloads.MysqL.com/archives/get/p/23/file/MysqL-5.7.28-linux-glibc2.12-x86_64.tar.gz
yum install -y libaio-devel

3.解压到指定目录

tar zxf MysqL-5.7.28-linux-glibc2.12-x86_64.tar.gz -C /opt/
mv /opt/MysqL-5.7.28-linux-glibc2.12-x86_64 /opt/MysqL-5.7.28

4.创建软链接

ln -s /opt/MysqL-5.7.28 /opt/MysqL

5.配置环境变量

echo 'export PATH=$PATH:/opt/MysqL/bin' >>/etc/profile
source /etc/profile
MysqL -V

6.编写配置文件

ccat> /etc/my.cnf <<EOF
[MysqLd]
port=3306
user=MysqL
basedir=/opt/MysqL
datadir=/data/MysqL_3306
socket=/tmp/MysqL_3306.sock

[MysqL]
socket=/tmp/MysqL_3306.sock
EOF

7.创建数据目录

mkdir -p /data/MysqL_3306

8.创建MysqL用户

useradd -s /sbin/nologin -M MysqL

9.授权软件目录和数据目录为MysqL

chown -R MysqL:MysqL /data/
chown -R MysqL:MysqL /opt/MysqL*

10.初始化数据库目录

MysqLd --initialize-insecure --user=MysqL --basedir=/opt/MysqL --datadir=/data/MysqL_3306/

11.复制启动文件并配置systemctl

cp /opt/MysqL/support-files/MysqL.server /etc/init.d/MysqLd
chkconfig --add MysqLd
systemctl start MysqLd

12.检查

netstat -lntup|grep 3306
MysqL

2.多实例安装配置

1.创建多实例的数据目录

mkdir -p /data/MysqL_330{7,8}
chown -R MysqL:MysqL /data/MysqL_330*

2.初始化数据库目录

MysqLd --initialize-insecure --user=MysqL --basedir=/opt/MysqL --datadir=/data/MysqL_3307/
MysqLd --initialize-insecure --user=MysqL --basedir=/opt/MysqL --datadir=/data/MysqL_3308/

3.创建多实例配置文件

cat >/data/MysqL_3307/my.cnf <<EOF
[MysqLd]
port=3307
user=MysqL
basedir=/opt/MysqL
datadir=/data/MysqL_3307
socket=/tmp/MysqL_3307.sock

[MysqL]
socket=/tmp/MysqL_3307.sock
EOF

cat >/data/MysqL_3308/my.cnf <<EOF
[MysqLd]
port=3308
user=MysqL
basedir=/opt/MysqL
datadir=/data/MysqL_3308
socket=/tmp/MysqL_3308.sock

[MysqL]
socket=/tmp/MysqL_3308.sock
EOF

4.配置启动文件

cat >/etc/systemd/system/MysqLd_3307.service <<EOF
[Unit]
Description=MysqL Server
Documentation=man:MysqLd(8)
Documentation=http://dev.MysqL.com/doc/refman/en/using-systemd.html
After=network.target
After=syslog.target
[Install]
WantedBy=multi-user.target
[Service]
User=MysqL
Group=MysqL
ExecStart=/opt/MysqL/bin/MysqLd --defaults-file=/data/MysqL_3307/my.cnf
LimitNOFILE = 5000
EOF

cat >/etc/systemd/system/MysqLd_3308.service <<EOF
[Unit]
Description=MysqL Server
Documentation=man:MysqLd(8)
Documentation=http://dev.MysqL.com/doc/refman/en/using-systemd.html
After=network.target
After=syslog.target
[Install]
WantedBy=multi-user.target
[Service]
User=MysqL
Group=MysqL
ExecStart=/opt/MysqL/bin/MysqLd --defaults-file=/data/MysqL_3308/my.cnf
LimitNOFILE = 5000
EOF

5.重载并重启

systemctl daemon-reload
systemctl start MysqLd_3307.service MysqLd_3308.service

6.检查多实例是否启动成功查看端口

netstat -lntup|grep 330*

7.配置密码

MysqLadmin password -S /tmp/MysqL_3307.sock
MysqLadmin password -S /tmp/MysqL_3308.sock

8.登陆多实例

MysqL -S /tmp/MysqL_3307.sock -p
MysqL -S /tmp/MysqL_3308.sock -p
