配置阿里源

# 进入目录
cd /etc/yum.repos.d
​
# 备份
mv CentOS-Base.repo CentOS-Base.repo.bak
​
# 下载阿里源
wget http://mirrors.aliyun.com/repo/Centos-7.repo
​
# 更改名字
sudo mv Centos-7.repo ./CentOS-Base.repo
​
​
# yum clean all
# yum makecache
# yum update

关闭防火墙

systemctl stop firewalld.service
systemctl disable firewalld.service

关闭selinux

# 临时关闭
setenforce 0
sed 's#SELINUX=enforcing#SELINUX=disabled#g' /etc/selinux/config

安装Nginx步骤

安装GCC编译器

yum install gcc gcc-c++ -y

下载Nginx-1.12.2并创建www用户

wget http://nginx.org/download/nginx-1.12.2.tar.gz 
useradd -M -s /sbin/nologin www

安装Nginx支持包并解压

yum install -y pcre-devel zlib-devel openssl-devel
tar zxf nginx

编译Nginx

cd nginx-1.12.2
./configure --prefix=/usr/local/nginx --with-http_dav_module --with-http_stub_status_module   --with-http_addition_module --with-http_sub_module  --with-http_flv_module --with-http_mp4_module --with-pcre --with-http_ssl_module --with-http_gzip_static_module  --user=www ;make && make install

设置Nginx软连接

ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin/
​
# 启动
nginx

# 检查服务
netstat -lntp |grep 80

升级到Nginx-1.18.0

wget  http://nginx.org/download/nginx-1.18.0.tar.gz
tar xvf nginx-1.18.0.tar.gz
# 升级前版本检查
nginx -V

编译安装更新

cd nginx-1.18.0
​
./configure --prefix=/usr/local/nginx --with-http_dav_module --with-http_stub_status_module   --with-http_addition_module --with-http_sub_module  --with-http_flv_module --with-http_mp4_module --with-pcre --with-http_ssl_module --with-http_gzip_static_module  --user=www ;make && make install
​
# 升级后版本检查
nginx -V

升级后检查服务是否正常

netstat -lntp |grep 80

安装Mysql

先删除系统自带的数据库

rpm -qa |grep mariadb
rpm -qa |grep mysql
# 删除
rpm -e mysql --nodeps
rmp -e mariadb --nodeps

下载二进制包

wget https://downloads.mysql.com/archives/get/p/23/file/mysql-5.7.18-linux-glibc2.5-x86_64.tar.gz
# 解压二进制包
tar zxf mysql-5.7.18-linux-glibc2.5-x86_64.tar.gz

安装前准备

创建工作目录

# 将解压的二进制包拷贝到/usr/local/mysql下
mv mysql-5.7.18-linux-glibc2.5-x86_64.tar.gz  mkdir /usr/local/mysql
# 创建data目录与log目录
mkdir /usr/local/mysql/data 
mkdir /usr/local/mysql/log
chmod 755 /usr/local/mysql/data/

设置环境变量与创建用户组

# 设置环境变量
echo "export PATH=$PATH:/usr/local/mysql/bin" >> /etc/profile && source /etc/profile
# 创建用户组与用户
groupadd mysql && useradd -r -g mysql -s /bin/false mysql

创建Mysql主配置文件

# 备份原始主配置文件
cp /etc/my.cnf  /etc/my.cnf.bak
​
vim /etc/my.cnf
[client]  
socket=/usr/local/mysql/mysql.sock  
[mysqld]  
basedir=/usr/local/mysql  
datadir=/usr/local/mysql/data  
pid-file=/usr/local/mysql/data/mysqld.pid  
socket=/usr/local/mysql/mysql.sock  
log_error=/usr/local/mysql/log/mysql.err

设置权限并初始化Mysql

cd /usr/local/mysql
chmod 750 data/ && chown -R mysql . && chgrp -R mysql . && bin/mysqld --initialize --user=mysql

创建Mysql启动脚本

cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld service mysqld start
# 检查启动
netstat -lntp |grep 3306
