linux配置基本业务

1.安装一些必备软件

yum install openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel sqlite-devel gcc gcc-c++  openssl-devel zlib zlib-devel -y

2.源码包安装

cd /opt

1）python3.6源码包安装

./configure

make

make install

2)mysql源码包

cmake

make

make install

3)redis

make

修改环境变量

vim /etc/profile

添加以下一行

export PATH=/opt/redis-3.2.10/src:$PATH

生效配置

source /etc/profile

3让python连接redis

unzip redis-py-master.zip
cd redis-py-master
python3 setup.py install

对redis的单实例进行连接操作
python3
>>>import redis
>>>r = redis.StrictRedis(host='localhost', port=6379)
>>>r.set('name', 'oldguo')
True
>>>r.get('name')
'oldguo'

3. 二进制包(mysql5.7.20)

3.1 解压及制作软连接
tar xf mysql-5.7.20-linux-glibc2.12-x86_64.tar.gz
ln -s mysql-5.7.20-linux-glibc2.12-x86_64 mysql

3.2 编辑环境变量
vim /etc/profile
添加以下一行:
export PATH=/opt/mysql/bin:$PATH

生效配置:
source /etc/profile

3.3 卸载自带mariadb
yum remove mariadb-libs

3.4 生成配置文件(/etc/my.cnf)
vim /etc/my.cnf
[mysqld]
basedir=/opt/mysql
datadir=/opt/mysql/data
socket=/tmp/mysql.sock
user=mysql
log_error=/var/log/mysql.log
log_bin=/opt/mysql/data/mysql-bin
server_id=100
[mysql]
socket=/tmp/mysql.sock

3.5 创建用户和数据目录,并授权
useradd mysql
mkdir /opt/mysql/data
chown -R mysql.mysql /opt/mysql

3.6 初始化数据

[root@python3 ~]# mysqld --initialize-insecure --basedir=/opt/mysql --datadir=/opt/mysql/data --user=mysql

3.7 启动mysql
cd /opt/mysql/support-files
./mysql.server start

cp mysql.server /etc/init.d/mysqld

/etc/init.d/mysqld restart

扩展:使用systemctl 管理mysql
vim /etc/systemd/system/mysqld.service

[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=/etc/my.cnf
LimitNOFILE = 5000

systemctl restart mysqld

netstat -tulnp |grep 3306

3.8 测试python3链接mysql

创建mysql链接用户

grant all on *.* to root@'10.0.0.%' identified by '123';
create database bbs charset utf8;

python代码测试:

pip3 install --upgrade pip
pip3 install pymysql

vim testmysql.py
#!/usr/bin/python3
import pymysql
db = pymysql.connect("10.0.0.100","root","123","bbs" )
cursor.execute("SELECT VERSION()")
data = cursor.fetchone()
print ("Database version : %s " % data)
db.close()

python3 testmysql.py

4.经典互联网架构项目(LNMP)

LNMPT = Linux Nginx MySQL PHP
LNMPJ = Linux Nginx MySQL PHP

LNMP架构环境部署
1) 使用官方Nginx yum源

[root@nginx ~]# vim /etc/yum.repos.d/nginx.repo
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/7/$basearch/
gpgcheck=0
enabled=1

#安装Nginx
[root@nginx ~]# yum install nginx -y
2) 启动Nginx，并将Nginx加入开机自启

systemctl start nginx
systemctl enable nginx
3) 使用第三方扩展源安装php7.1

rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

[root@nginx ~]# yum remove php-mysql-5.4 php php-fpm php-common
[root@nginx ~]# vim /etc/yum.repos.d/php.repo
[php]
name = php Repository
baseurl = http://us-east.repo.webtatic.com/yum/el7/x86_64/
gpgcheck = 0

[root@nginx ~]# yum -y install php71w php71w-cli php71w-common php71w-devel php71w-embedded php71w-gd php71w-mcrypt php71w-mbstring php71w-pdo php71w-xml php71w-fpm php71w-mysqlnd php71w-opcache php71w-pecl-memcached php71w-pecl-redis php71w-pecl-mongodb
3) 配置php-fpm用户与Nginx的运行用户保持一致

[root@nginx ~]# sed -i '/^user/c user = www' /etc/php-fpm.d/www.conf
[root@nginx ~]# sed -i '/^group/c group = www' /etc/php-fpm.d/www.conf
4) 启动php-fpm，并将其加入开机自启

[root@nginx ~]# systemctl start php-fpm
[root@nginx ~]# systemctl enable php-fpm
5) 安装mysql数据库

[root@nginx ~]# mysqladmin password '123'
[root@nginx ~]# mysql -uroot -p123
2.LNMP架构环境配置

vim /etc/nginx/conf.d/php.conf
server {
server_name 10.0.0.12;
listen 80;
root /code/wordpress;
index index.php index.html;

location ~ \.php$ {
root /code/bbs;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}
