基础环境搭建

Centos7下环境搭建

CentOS更改yum源与更新系统

[1]首先备份/etc/yum.repos.d/CentOS-Base.repo

mv/etc/yum.repos.d/CentOS-Base.repo/etc/yum.repos.d/CentOS-Base.repo.backup

[2]进入yum源配置文件所在文件夹

[root@localhostyum.repos.d]# cd /etc/yum.repos.d/

[3]下载163的yum源配置文件，放入/etc/yum.repos.d/(操作前请做好相应备份)

[root@localhost

yum.repos.d]#wgethttp://mirrors.163.com/.help/CentOS6-Base-163.repo

[4]运行yum makecache生成缓存

[root@localhostyum.repos.d]# yum makecache

[5]更新系统

[root@localhostyum.repos.d]# yum -y update

[6]安装vim编辑器

[root@localhost

~]# yum -yinstallvim*

[6]安装ifconfig、telnet

yum install net-tools

yum install telnet

java jdk安装

1、新建文件夹

Make dir /usr/java

2、解压压缩包

3、配置环境变量

vi /etc/profile

JAVA_HOME=/usr/java/jdk1.8.0_25

PATH=$JAVA_HOME/bin:$PATH

CLASSPATH=$JAVA_HOME/jre/lib/ext:$JAVA_HOME/lib/tools.jar

export PATH JAVA_HOME CLASSPATH

source /etc/profile

Python3安装

1、安装python3可能使用的依赖

yuminstall openssl-devel bzip2-devel expat-devel gdbm-devel readline-develsqlite-devel

2、下载python包，解压后，移动到/usr/local下

3、进入Python目录

执行：

./configure--prefix=/usr/local/python3

make && make install

4、创建新的软链接到最新的python

# ln-s /usr/local/python3/bin/python3 /usr/bin/python3

# ln-s /usr/local/python3/bin/pip3.6  /usr/bin/pip3

postgresql安装

1.添加RPM

yum installhttps://download.postgresql.org/pub/repos/yum/9.5/redhat/rhel-7-x86_64/pgdg-centos95-9.5-2.noarch.rpm

2.安装PostgreSQL9.5

yum install postgresql95-server postgresql95-contrib

3.初始化数据库

/usr/pgsql-9.5/bin/postgresql95-setup initdb

4.设置开机自启动

systemctl enable postgresql-9.5.service

5.启动服务

systemctl start postgresql-9.5.service

6.修改用户密码

su - postgres

psql -U postgres

ALTER USER postgres WITH PASSWORD 'abc123';

7.开启远程访问

vi /var/lib/pgsql/9.5/data/postgresql.conf

修改#listen_addresses = 'localhost'为listen_addresses='*'

8.信任远程连接

vi /var/lib/pgsql/9.5/data/pg_hba.conf

修改如下内容，信任指定服务器连接

# IPv4 local connections:

host    all           all      127.0.0.1/32     trust

host    all            all0.0.0.0/32trust

9.打开防火墙

lsfirewall-cmd --add-service=postgresql --permanent开放服务

irewall-cmd --reload重载防火墙

10.重启PostgreSQL数据服务

systemctl restart

postgresql-9.5.service

redis安装

1、安装gcc和tcl

yum install gcc

yum install tcl

2、下载最新安装包

wget http://download.redis.io/redis-stable.tar.gz

tar zxvf

redis-stable.tar.gz

cd redis-stable

make &&

sudo make install

如果报错：

Make执行带参数：make MALLOC=libc

3.启动

redis-server redis.conf

nginx安装

1、安装依赖包

yum install gcc-c++

yum install -y pcrepcre-devel

yum install -y zlib

zlib-devel

yum install -yopenssl openssl-devel

2、下载nginx

Wgethttp://nginx.org/download/nginx-1.12.1.tar.gz

3、安装

tar xzvf nginx-1.12.1.tar.gz

cd nginx-1.10.1

./configure#使用默认配置

Make && make install

4、启动

cd/usr/local/nginx/sbin

./nginx#启动

./nginx -s stop

./nginx -s quit

./nginx -s reload

增加一行/usr/local/nginx/sbin/nginx

设置执行权限：

chmod755rc.local
