常见系统安装

nginx

参考文件：
nginx中文文档，https://www.nginx.cn/install

环境准备

1. 安装make
   yum -y install gcc automake autoconf libtool make

2. 安装g++
   yum install gcc gcc-c++

3. 安装pcre(为了重写依赖)
   cd /usr/local/src
   wget https://ftp.pcre.org/pub/pcre/pcre-8.44.tar.gz
   tar -zxvf pcre-8.44.tar.gz
   cd pcre-8.44
   ./configure
   make
   make install

4. 安装zlib（为了解压缩）
   wget http://zlib.net/zlib-1.2.11.tar.gz
   tar -zxvf zlib-1.2.11.tar.gz
   cd zlib-1.2.11
   ./configure
   make
   make install

5. 安装openssl(不是必要)
   cd /usr/local/src
   wget https://www.openssl.org/source/openssl-1.1.1g.tar.gz
   tar -zxvf openssl-1.1.1g.tar.gz

6. 安装nginx
   cd /usr/local/src
   wget http://nginx.org/download/nginx-1.18.0.tar.gz
   tar -zxvf nginx-1.18.0.tar.gz
   cd nginx-1.18.0

./configure --sbin-path=/usr/local/nginx/nginx
--conf-path=/usr/local/nginx/nginx.conf
--pid-path=/usr/local/nginx/nginx.pid
--with-http_gzip_static_module
--with-http_stub_status_module
--with-file-aio
--with-http_realip_module
--with-http_ssl_module
--with-pcre=/usr/local/src/pcre-8.44
--with-zlib=/usr/local/src/zlib-1.2.11
--with-openssl=/usr/local/src/openssl-1.1.1g

make -j2
make install

6、创建软连接
ln -s /usr/local/nginx/nginx /usr/local/bin/

7、其他
nginx默认占用80端口，外面可能需要开放端口号

redis

下载文件

先安装5.x版本，6.0版本安装有些问题
wget http://download.redis.io/releases/redis-5.0.5.tar.gz
tar zxvf redis-5.0.5.tar.gz
cd redis-5.0.5

编译

make MALLOC=libc2

安装

make install PREFIX=/usr/local/redis
cp redis.conf /usr/local/redis/redis.conf

python3

基础环境检查

1. gcc安装
   yum -y install gcc
2. 其他依赖
   yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel libffi-devel

安装

1. 下载源码
   wget https://www.python.org/ftp/python/3.8.2/Python-3.8.2.tgz
   解压：tar -zxvf Python-3.8.2.tgz
   cd Python-3.8.2

2. 安装
   创建文件夹：mkdir /usr/local/python3
   ./configure --prefix=/usr/local/python3
   make && make install

3. 建立软连接
   ln -s /usr/local/python3/bin/python3.8 /usr/bin/python3
   ln -s /usr/local/python3/bin/pip3.8 /usr/bin/pip3

4. 测试
   python3

mysql8

基础

安装MySQL RPM包

1. 下载RPM文件
   wget https://dev.mysql.com/get/mysql80-community-release-el7-1.noarch.rpm
2. 安装RPM源
   yum localinstall mysql80-community-release-el7-1.noarch.rpm
3. 查看本地源是否安装成功
   yum repolist enabled | grep "mysql.-community."

安装MySQL

1. 安装MySQL Server
   yum install mysql-community-server
2. 启动mysql服务
   service mysqld start
3. 设为开机启动
   systemctl enable mysqld
   systemctl daemon-reload
4. 查看是否启动
   service mysqld status

MySQL数据修改

1. 查看临时密码
   grep 'temporary password' /var/log/mysqld.log
2. 修改密码
   mysql -uroot -p
   use mysql
   alter user 'root'@'%' identified with mysql_native_password by 'Shx_11111';
3. 允许远程用户登陆
   grant all on . to 'root'@'%';
   flush privileges;
