centos7 部署mysql-5.7.20

一、系统环境

系统：CentOS Linux release 7.5

mysqlb进制包：mysql-5.7.20-linux-glibc2.12-x86_64.tar.gz

1）依赖包安装

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 libcurl-devel libcurl freetype-config freetype freetype-devel unixODBC libxslt
yum -y install libtool openssl-devel
yum -y install perl-devel perl-ExtUtils-Embed
yum -y install ncurses-devel.x86_64 openldap-devel.x86_64 lrzsz openssh-clients gcc-g77 bison
yum -y install libmcrypt libmcrypt-devel mhash mhash-devel bzip2 bzip2-devel
yum -y install ntpdate rsync svn patch iptables iptables-services
yum -y install libevent libevent-devel cyrus-sasl cyrus-sasl-devel
yum -y install gd-devel libmemcached-devel memcached git libssl-devel libyaml-devel auto
yum -y install gcc gcc-c++ make autoconf automake ncurses-devel ncurses cmake libaio libaio-devel boost

2）关闭selinux

sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config
setenforce  0

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
kernel.shmmax = 137438953472
kernel.shmall = 4294967296
kernel.shmmni = 4096
net.ipv4.ip_local_port_range = 9000 65500
net.ipv4.tcp_mem = 94500000 915000000 927000000
net.core.wmem_default = 8388608
net.core.rmem_default = 8388608
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216
net.ipv4.tcp_rmem = 4096 87380 16777216
net.ipv4.tcp_wmem = 4096 65536 16777216
net.core.netdev_max_backlog = 32768
net.ipv4.tcp_tw_recycle = 1
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_fin_timeout = 10
net.ipv4.tcp_keepalive_time = 300
net.ipv4.tcp_max_syn_backlog = 32768
net.ipv4.tcp_syncookies = 1
net.ipv4.tcp_timestamps = 0
net.ipv4.conf.default.accept_source_route = 0
vm.swappiness=1
EOF

# 使其生效
sysctl -p

二、创建mysql目录

mkdir -pv /home/usr/local

三、解压文件并且需要改目录名

tar xf mysql-5.7.20-linux-glibc2.12-x86_64.tar.gz

mv mysql-5.7.20-linux-glibc2.12-x86_64 mysql5.7

四、创建用户和用户组

groupadd mysql

useradd -r -g mysql mysql

五、创建mysql数据目录

mkdir -pv /home/usr/local/mysql5.7/{data,logs,tmp}

六、授权mysql目录权限

chown -R mysql:mysql mysql5.7

七、备份原始的my.cnf 配置文件

mv /etc/my.cnf /etc/my.cnf.bak

八、创建新的配置文件



cat >  /etc/my.cnf <<EOF
