安装mariadb

1、 cd /usr/local/src //切换到下载源码包的目录

[root@aminglinux ~]# cd /usr/local/src

2、官网下载：mariadb-galera-5.5.61-linux-x86_64.tar.gz上传到/usr/local/src目录

3、解压：tar zxvf mariadb-galera-5.5.61-linux-x86_64

4、解压的包移动到/usr/local/mariadb下

[root@aminglinux src]# mv mariadb-galera-5.5.61-linux-x86_64 /usr/local/mariadb
[root@aminglinux src]# cd /usr/local/mariadb

5、useradd mysql //创建一个mysql用户

[root@aminglinux mysql]# useradd mysql

6、mkdir /data/ //创建一个目录，是为了存放mysql的数据，把数据目录放到这个目录下

[root@aminglinux mysql]# mkdir /data/

7、编译安装./scripts/mysql_install_db --user=mysql --basedir=/usr/local/mariadb/ --datadir=/data/mariadb

[root@aminglinux mariadb]# ./scripts/mysql_install_db --user=mysql --basedir=/usr/local/mariadb/ --datadir=/data/mariadb
[root@aminglinux mariadb]# echo $?
0

8、cp support-files/my-small.cnf /usr/local/mariadb/my.cnf 拷贝配置文件

[root@aminglinux mariadb]# cp support-files/my-small.cnf /usr/local/mariadb/my.cnf
[root@aminglinux mariadb]# ls
bin      data               include         lib  my.cnf      README        scripts  sql-bench
COPYING  EXCEPTIONS-CLIENT  INSTALL-BINARY  man  mysql-test  README-wsrep  share    support-files

9、拷贝启动脚本到/etc/init.d/mariadb并编辑：

cp support-files/mysql.server /etc/init.d/mariadb
vim /etc/init.d/mariadb //定义basedir、datadir、conf以及启动参数

[root@aminglinux mariadb]# cp support-files/mysql.server /etc/init.d/mariadb
[root@aminglinux mariadb]# vim /etc/init.d/mariadb
# If you change base dir, you must also change datadir. These may get
# overwritten by settings in the MySQL configuration files.
 
basedir=/usr/local/mariadb 定义basedir
datadir=/data/mariadb   定义datadir
conf=$basedir/my.cnf    自定义参数（配置文件在/etc下不用定义这个参数）

配置启动命令：在一般模式下，搜索 /start 启动命令

在 $bindir/mysqld_safe --datadir="$datadir" --pid-file="$mysqld_pid_file_path" "$@" &中，增加--defaults-file="$conf"；
最后为 $bindir/mysqld_safe --defaults-file="$conf" --datadir="$datadir" --pid-file="$mysqld_pid_file_path" "$@" &

10、编辑指定的配置文件，在 /usr/local/mariadb/my.cnf 文件中的 [mysqld] 下加入datadir= /data/mariadb

[root@aminglinux mariadb]# vim /usr/local/mariadb/my.cnf
# The MySQL server
[mysqld]
datadir= /data/mariadb
port            = 3306
socket          = /tmp/mysql.sock
skip-external-locking
key_buffer_size = 16K
max_allowed_packet = 1M

11、启动/etc/init.d/mariadb start

[root@aminglinux mariadb]# /etc/init.d/mariadb start
Starting MariaDB.180804 00:46:16 mysqld_safe Logging to '/data/mariadb/aminglinux.err'.
180804 00:46:16 mysqld_safe Starting mysqld daemon with databases from /data/mariadb
... SUCCESS! 
[root@aminglinux mariadb]# ps aux |grep mysql

mysql     6775  0.2  8.2 665212 83148 pts/0    Sl   00:46   0:00 /usr/local/mariadb/bin/mysqld --defaults-file= --basedir=/usr/local/mariadb --datadir=/data/mariadb --plugin-dir=/usr/local/mariadb/lib/plugin --user=mysql --log-error=/data/mariadb/aminglinux.err --pid-file=/data/mariadb/aminglinux.pid --wsrep_start_position=00000000-0000-0000-0000-000000000000:-1
root      6845  0.0  0.0 112720   984 pts/0    S+   00:47   0:00 grep --color=auto mysql

PHP安装

1、进入目录：cd /usr/local/src/

2、下载PHP5.6.33包：wget http://cn2.php.net/distributions/php-5.6.33.tar.gz

3、解压：tar zxvf php-5.6.33.tar.gz

4、创建账号：useradd -s /sbin/nologin php-fpm

5、进入目录：cd php-5.6.33

6、编译PHP5.6:

[root@localhost src]# cd php-5.6.33 
[root@localhost php-5.6.33]# ./configure --prefix=/usr/local/php-fpm --with-config-file-path=/usr/local/php-fpm/etc --enable-fpm --with-fpm-user=php-fpm --with-fpm-group=php-fpm --with-mysql=/usr/local/mariadb --with-mysqli=/usr/local/mariadb/bin/mysql_config --with-pdo-mysql=/usr/local/mariadb --with-mysql-sock=/tmp/mysql.sock --with-libxml-dir --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir --with-iconv-dir --with-zlib-dir --with-mcrypt --enable-soap --enable-gd-native-ttf --enable-ftp --enable-mbstring --enable-exif --with-pear --with-curl  --with-openssl

需注意mariadb路径

7、然后：make && make install

PHP安装可能会遇到缺少的包：

yum install -y gcc //gcc
yum install -y libxml2-devel //XML2
yum install -y openssl-devel //缺少OpenSSL
yum install -y bzip2-devel //缺少BZip2
yum install -y libjpeg-devel //缺少libjpeg
yum install -y libpng-devel //缺少libpng-devel
yum install -y freetype-devel //缺少freetype-devel
yum install -y libcurl-devel //缺少libcurl-devel
yum install -y epel-release && yum install -y libmcrypt-devel //缺少libmcrypt-devel

8、检查php-fpm核心文件及安装目录结构

9、从源码包里拷贝配置文件php.ini到php-fpm/etc/目录下：cp php.ini-production /usr/local/php-fpm/etc/php.ini

编辑php-fpm.conf配置文件

配置文件参考：https://coding.net/u/aminglinux/p/aminglinux-book/git/blob/master/D15Z/php-fpm.conf?public=true

[root@aminglinux php-5.6.33]# vim /usr/local/php-fpm/etc/php-fpm.conf

[global]
#定义全局参数
pid = /usr/local/php-fpm/var/run/php-fpm.pid
error_log = /usr/local/php-fpm/var/log/php-fpm.log
[www]
listen = /tmp/php-fcgi.sock
#监听地址，也可以写：listen = 127.0.0.1：:9000，本地监听，也可以监听其他IP：port
#此处格式会影响配置Nginx和PHP结合时Nginx寻址PHP的路径
listen.mode = 666
#当监听的为socket文件时该部分才生效，用于指定.sock文件的权限
user = php-fpm
group = php-fpm
#定义php-fpm服务的用户
pm = dynamic
pm.max_children = 50
pm.start_servers = 20
pm.min_spare_servers = 5
pm.max_spare_servers = 35
pm.max_requests = 500
rlimit_files = 1024

10、配置启动脚本

添加启动脚本到系统配置：
[root@localhost php-5.6.33]# cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
更改文件权限：
[root@localhost php-5.6.33]# chmod 755 /etc/init.d/php-fpm
添加到系统服务：
[root@localhost php-5.6.33]# chkconfig --add php-fpm
设置开机启动：
[root@localhost php-5.6.33]# chkconfig php-fpm on
启动php-fpm服务：
[root@localhost php-5.6.33]# service php-fpm start
Starting php-fpm  done

Nginx安装

1、cd /usr/local/src/ //进入目录

2、wget http://nginx.org/download/nginx-1.14.0.tar.gz //下载Nginx包

3、tar zxvf nginx-1.14.0.tar.gz 解压包

[root@aminglinux ~]# cd /usr/local/src/
[root@aminglinux src]# wget http://nginx.org/download/nginx-1.14.0.tar.gz
--2018-08-04 10:19:58--  http://nginx.org/download/nginx-1.14.0.tar.gz

2018-08-04 10:20:03 (230 KB/s) - 已保存 “nginx-1.14.0.tar.gz” [1016272/1016272])

[root@aminglinux src]# ls

[root@aminglinux src]# tar zxvf nginx-1.14.0.tar.gz

4、配置编译安装：

cd nginx-1.14.0
./configure --prefix=/usr/local/nginx
make && make install

5、修改、检查配置文件；脚本参考：https://coding.net/u/aminglinux/p/aminglinux-book/git/blob/master/D15Z/etc_init.d_nginx

[root@aminglinux nginx]# vim /etc/init.d/nginx

6、编辑启动脚本,修改为755权限;加入开机启动列表，设置开机启动：启动nginx服务

[root@aminglinux nginx]# chmod 755 /etc/init.d/nginx
[root@aminglinux nginx]# ls -l /etc/init.d/nginx
-rwxr-xr-x. 1 root root 1141 8月   4 10:27 /etc/init.d/nginx
[root@aminglinux nginx]# chkconfig --add nginx
[root@aminglinux nginx]# chkconfig nginx on
注意：正在将请求转发到“systemctl enable nginx.service”。
Created symlink from /etc/systemd/system/multi-user.target.wants/nginx.service to /usr/lib/systemd/system/nginx.service.
[root@aminglinux nginx]# /etc/init.d/nginx start
Starting nginx (via systemctl):                            [  确定  ]
[root@aminglinux nginx]#

7、更改Nginx配置文件，配置文件脚本参考：https://coding.net/u/aminglinux/p/aminglinux-book/git/blob/master/D15Z/nginx.conf

[root@aminglinux conf]# vim nginx.conf
[root@aminglinux conf]# /usr/local/nginx/sbin/nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
[root@aminglinux conf]# /etc/init.d/nginx restart
Restarting nginx (via systemctl):                          [  确定  ]
[root@aminglinux conf]#

systemctl stop firewalld 关闭firewalld
setenforce 0 临时关闭selinux

安装discuz论坛

1、创建目录 mkdir -p /data/wwwroot/bbs/ 存放discuz程序的根目录

[root@aminglinux ~]# mkdir -p /data/wwwroot/bbs/

2、下载discuz包并解压；把upload目录下文件拷贝到/data/wwwroot/bbs/

[root@aminglinux ~]# cd /usr/local/src/
[root@aminglinux src]# wget http://download.comsenz.com/DiscuzX/3.3/Discuz_X3.3_SC_UTF8.zip

解压

[root@aminglinux src]# unzip Discuz_X3.3_SC_UTF8.zip

把upload目录下文件拷贝到/data/wwwroot/bbs/

[root@aminglinux src]# ls
5.5.html            Discuz_X3.3_SC_UTF8.zip  mariadb-galera-5.5.61-linux-x86_64.tar.gz  php-5.6.33         utility
